Executive Summary
Wave Dynamics were engaged by Fine Living Timber Frames Limited to undertake a noise impact assessment
for a planning retention application for an existing yard and change of use from retail to manufacturing facility
located at Lakeview Business Park, Castleblayney, Co. Monaghan A75A386. A request for further information
has been issued by the planning authority on the submitted application, the RFI states the following with regard to
noise:
a) Section 15.12.1 ‘Industrial and Commercial Developments within Tier 1 -4 settlements’ of the Monaghan
County Development Plan 2025-2031, states that the impact of commercial/industrial proposals on
residential amenity must be carefully assessed. Notwithstanding the findings and proposed mitigation
measures contained in the submitted noise assessment, the Planning Authority has concerns that the
proposed development would adversely affect the amenity of neighbouring residents due to the nature
of operations proposed, the sites proximity to nearest noise sensitive locations, the proposed 24 -hour
operating hours and the proposed hours of delivery. The Planning Authority is of the opinion that
operations and deliveries should be restricted to the hours of 07:00 hours to 20:00 hours, in the interests
of safeguarding local residential amenity. Having regard to same, the applicant is requested to submit
amended proposals, including an updated noise assessment, to reflect same.
b) It is noted that there is a discrepancy within the submitted noise assessment in terms of the proposed
hours of delivery i.e. page 3, 11, and 14 refer to hours of delivery of between 07:00hrs and 21:00hrs,
whereas page 16 states that there will be ‘No external works or deliveries during the night-time period of
23:00hrs-07:00hrs.’ The applicant is requested to provide clarification with regard to same.
c) The Planning Authority notes that no details have been provided with regard to proposed dust
mitigation/suppression methods associated with the proposed use and internal operations. The
applicant is therefore requested to provide the following;
i. Details of any proposed dust mitigation/suppression methods.
ii. Where this includes extractor fans or other similar noise emitting plant, these should be
assessed as part of a revised noise report, and details/specifications provided.
The development consists of:
“Retention permission for an existing external yard storage building with full permission sought for a change of
use from an existing retail outlet (RB Coogan) to a timber frame manufacturing facility with ancillary office and
staff facilities; elevational changes, new signage, an extension to the existing external yard storage building, new
plant room / ancillary store, alterations to the existing car parking areas, revised boundary treatments and all
associated site development works.”
Attended and unattended noise surveys were undertaken to measure the existing noise levels in the area and
quantify the existing noise environment. This report outlines the project criteria, survey results, assessment, and
general guidance recommendations for:
• Operational noise from the proposed facility and associated activity.
Appendix A outlines a glossary of the acoustic terminology used in this report.
Noise Impact Assessment
An attended baseline survey was conducted to establish the existing noise environment and project criteria.
Based on the assumed operating hours of the facility (07:00hrs – 20:00hrs) the proposed development has the
potential to cause negative noise impact during the daytime period.
A preliminary assessment of the proposed facilities noise emissions was conducted. It was deemed to exceed
project criteria significantly and therefore mitigation measures have been recommended in this report to reduce RECEIVED: 16/03/2026
www.wdacoustics.com WDA251188RP_C_01 Noise Impact Assessment
the predicted noise emissions from the proposed facility to suitable levels and into compliance with project
criteria. Section 5.2 outlines the mitigation strategy in full. Mitigation measures are to be implemented in full to
satisfy compliance with project criteria.
Predicted resulting daytime operational noise levels from the proposed facility and operations have been
assessed using a BS4142 assessment which predicted that there will be a low impact at all noise sensitive
receptors during the daytime period with the mitigation measures outlined in this report implemented in full. The
predicted noise levels from the development have been compared with EPA NG4 which was predicted to comply
at all noise sensitive locations.
The RFI issued by the planning authority in relation to noise emissions from proposed dust extraction for the
proposed development has been addressed in Section 5. The location and noise levels of the proposed dust
suppression system have been factored into the assessment and deemed to not cause any additional noise
impact at the surrounding noise sensitive receptors. The extraction/suppression system does not feature any
external fans based on the information provided by the client and design team.
Based on the assessment and recommendations outlined in this report it is predicted that noise levels at
the proposed facility will comply with the project criteria, mitigation measures are to be incorporated in
full. RECEIVED: 16/03/2026

3 Project Criteria
The acoustic criteria for the project are set out in this section, the purpose of the criteria is to ensure reasonable:
• Noise levels from the operation of the proposed facility and associated activities.
To provide adequate conditions Wave Dynamics have developed the project criteria for:
• Operational noise.
Acoustic Standards
The acoustic standards for assessing noise impact for the project have been developed from the following:
✓ BS4142 2014 A1+ 2019 Methods for rating and assessing industrial and commercial sound.
✓ Environmental Protection Agency NG4: Guidance note for Noise: Licence Applications, Surveys and
Assessments in Relation to Scheduled Activities.
✓ Monaghan Noise Action Plan 2024 – 2028.
✓ BS 8233:2014 Guidance on sound insulation and noise reduction for buildings.
✓ ISO 1996-1:2016 Acoustics — Description, measurement and assessment of environmental noise —
Part 1: Basic quantities and assessment procedures.
✓ Previous experience on similar projects.
3.1 Operational Noise Assessment Criteria
Local authorities can set noise limits from typical commercial premises pertaining to noise however there is
currently no national policy for operational noise limits from industrial facilities for planning noise assessments.
Noise limits for new developments are typically sought from local council’s noise action plan , EPA NG4 or BS4142.
On review of the Monaghan County Council Noise Action Plan no specific guidance has been outlined for noise
limits from commercial premises and therefore the criteria from EPA NG4 and BS4142 has been adopted for the
project.
BS 4142:2014+A1:2019
The standard describes a method for the assessment of commercial, industrial and background noise to quantify
its impact on persons outside of a residential dwelling. BS 4142 has become the de facto standard for compliance
investigation. In addition to the specified broadband noise levels the standards provide objective and subjective
methods for the assessment of the impulsivity and tonality of the noise sources. This allows for a penalty/ correction
to be applied to the measured noise level of the source (LAeq) to give the rating level (LAr,T).
• Typically, the greater this difference, the greater the magnitude of the impact.
• A difference of around +10 dB or more is likely to be an indication of a significant adverse impact,
depending on the context.
• A difference of around +5 dB is likely to be an indication of an adverse impact, depending on the
context.
• The lower the rating level is relative to the measured background sound level, the less likely it is that the
specific sound source will have an adverse impact or a significant adverse impact. Where the rating
level does not exceed the background sound lev el, this is an indication of the specific sound source
having a low impact, depending on the context.
Adverse impacts include, but are not limited to, annoyance and sleep disturbance.
• Response to sound can be subjective and is affected by many factors, both acoustic and non-acoustic.
The significance of its impact, for example, can depend on such factors as the margin by which a sound RECEIVED: 16/03/2026
www.wdacoustics.com Page 6 of 22 WDA251188RP_C_01 Noise Impact Assessment
exceeds the background sound level, its absolute level, time of day and change in the acoustic
environment, as well as local attitudes to the source of the sound and the character of the
neighbourhood.
EPA NG4
EPA NG4 outlines that noise attributable solely to onsite activities from a licenced premises should not exceed
the following limits:
• Daytime (07:00hrs – 19:00hrs) – 55dB LAr,T
• Evening (19:00hrs – 23:00hrs) – 50dB LAr,T
• Nighttime (23:00hrs – 07:00hrs) – 45dB LAeq,T
During daytime and evening periods rigorous efforts should be made to avoid clearly audible tones and impulsive
noise at all sensitive locations. A penalty of 5dB for tonal and/or impulsive elements is to be applied to the
daytime and evening measured LAeq,T values to determine the appropriate rating level (LAr,T). In all cases, an
assessment by a competent person will be required.
During the night-time period no tonal or impulsive noise from the facility should be clearly audible or measurable
at any NSL.

4 Baseline Noise Survey
4.1 Baseline Noise Survey
An attended baseline noise survey was conducted to assess the background noise levels. Multiple locations were
chosen to conduct the survey to establish the background noise at the closest noise sensitive locations to the
proposed facility. The attended measurements included measurements of background noise during the daytime
and nighttime periods. The purpose of the attended measurements was to establish the background noise levels
in the area, and to use these measurements for predicting the noise impact of the proposed development on the
area.
4.1.1 Measurement Locations
The proposed development is located at Lakeview Business Park, Castleblayney, Co. Monaghan A75A386. The
premises is bounded by green fields to the north and west, with commercial developments to the east. There are

5 Noise Impact Assessment
Following the survey a model of the development using SoundPLAN 9.1 modelling software was developed to
establish the noise levels from the development in a worst-case scenario. The software implements the
algorithms contained in ISO 9613-1 and ISO 9613-2. The noise model considers:
o Distance attenuation,
o Source and receptor locations,
o Barrier effects (buildings, walls etc)
o Topographical elevations,
o Ground effects and absorption,
o Source sound power levels,
o Directivity and orientation of the source,
o Atmospheric attenuation and meteorological effects,
The acoustic model for the site has been developed based on the site proposals, site location and predicted
noise sources. A worst-case scenario has been developed predicting the following external noise sources :
• Internal noise sources include various lumber processing saws, panel saws, assembly stations and
various nail gun and strip nailing activities, as noted in Figure 4.
• Usage of roller shutter doors for materials in/out.
• HGV movements in/out of the yard areas.
• Forklifts loading/unloading.
• Staff traffic in/out of the proposed development.

The dust collector utilises a clean-side fan to pull contaminated air from the extraction pipes into the filter
housing. Contaminants are separated as they accumulate on the outer surface of the filters. Purified air is then
discharged from the upper section of the machine. The system is engineered to maintain a residual dust
concentration below 0.1 mg/m3, fully complying with H3 safety standards for air return. Figure 6 outlines the
storage of dust in the extraction process for manual cleaning/disposal.

5.2 Mitigation Measures
A provisional assessment of the noise levels inside the facility and in the external yard led to the determination of
noise levels in excess of measured background noise levels, and therefore a determination of non -compliance
with project criteria. In order for the proposed development to comply with project criteria, mitigation measures
are required to reduce the noise emissions from the proposed development. Mitigation measures include
upgrades to the building fabric of the existing warehouse building along with external mitigation measures
particularly along the roller shutter doors for the delivery and offload of materials.
Building Fabric
Table 7 outlines the required performance of the building fabric to achieve compliance with project criteria . The
external construction of the existing warehouse building is assumed to achieve a performance of 25dB R W, in line
with products such as Kingspan KS1000 panel. This will need to be upgraded to achieve a minimum performance
of 50dB RW in order to achieve compliance with project criteria, given the extensive noise generating activities
inside the proposed facility.

External Upgrade Works
Based on the internal noise levels and the assumed existing roller shutter door performance, mitigation measures
will be required around the roller shutter doors in order to reduce the noise impact as the surrounding noise
sensitive receptors. The mitigation strategy includes noise barriers and overhead screens to attenuate noise
emissions from the loading bays. Noise barriers to a height of 5m (the entire height of the loading bay doors),
extending 6m from the façade with a solid covering/canopy along the northeastern elevation as outlined in Figure
7, for the northwestern elevation a noise barrier extending to 5m in height and 4m from the façade with a solid
covering/canopy above as outlined in Figure 8. The external mitigation is required to control noise emissions with
the roller shutter doors in the open and closed positions.

The noise walls can be constructed from any of the following materials, provided that the barrier is solid with no
gaps or penetrations. The noise wall should achieve a density of 20 kg/m3 and can be constructed from:
• Concrete.
• Block.
• Glass.
• Timber.
3D Acoustic modelling
Following the site measurements and model, a noise impact assessment was undertaken. This considered the
contribution to the noise environment at the nearest noise sensitive locations from noise from the operation of the
new warehouse and comparison to the background noise. Th e following section outlines the assessment and
findings. Figure 9 outlines the 3D acoustic model.

5.3 Daytime Scenario
The noise impact at the nearest noise sensitive locations (NSL1 – NSL3) have been assessed in accordance with
BS 4142. NSL3 has been selected to be outlined in the BS4142 assessment as this NSL has the highest
predicted noise level from the proposed development. All other NSL’s are predicted to have lower onset noise
levels from the development and therefore NSL3 is the worst-case.
The daytime situation assumes the following noise sources:
• All internal equipment operating in line with values and operational times as outlined in Section 5.1.
• Roller shutter doors assumed in the open position.
• 2 HGV deliveries and 4 HGV shipments between the hours of 07:00hrs-20:00hrs only.
• Forklifts operating in the external yard and storage shed between the hours of 07:00 -20:00hrs only.
• Car parking spaces utilised 10% of the time during daytime hours of 07:00hrs-20:00hrs.

A 3dB impulsive characteristic
penalty has been applied to the

to the potentially impulsive nature of
nailing and assembly works.
Rating level (45 + 3) dB = 48dB 9.2
Background sound level LA90(60min) = 47dB 8
Excess of rating over
background sound level (48 - 47) dB = 1dB 11
Assessment indicates that no
adverse impact is likely on the noise
sensitive locations as the specific
sound is 1dB above the background
levels and is lower than the residual
sound. Context has also been
considered.
Uncertainty of the
assessment Not significant 10
The specific sound is a worst-case
prediction as the assessment
assumes the worst-case use of the
plant listed in Table 4 and Table 6.
Based on the review of the noise sources and the BS 4142 assessment it is predicted that the noise emanating
from the proposed development will have a low impact during the daytime period.
Tonality & Impulsivity
The tonality and impulsivity of the proposed development in operation have been considered as part of the
assessment. Based on the predicted noise levels and the nature of the proposed works, a subjective 3dB
correction has been applied to the specific source noise levels in line with BS 4142 guidance, it is not predicted
that impulsivity will lead to adverse noise conditions at the surrounding sensitive receptors as the predicted noise
levels are 1dB above the measured background noise levels and below the residual levels.
5.3.2 EPA NG4
EPA NG4 recommends a daytime criterion of (07:00hrs – 19:00hrs) 55dB LAr,T, the predicted noise emissions
from the proposed development are 50 dB LAr,T, with penalties applied for impulsivity, therefore the NG4 criteria is
expected to be achieved. It should be noted that EPA NG4 states that impulsivity should carry a 5dB penalty for
any sort of impulsive noise therefore this has been applied here.

6 Recommendations
This section outlines recommendations of additional mitigation and policies that can be used to ensure no
adverse impact on the nearby residential receptors. These should be implemented in addition to the mitigation
outlined in Section 5.2 which is to be implemented in full.
6.1 Noise Management Policy
A noise policy should be created by the facility occupiers and circulated to all staff members. The noise policy
should include but is not limited to policies on the following:
• Trucks, cars and vans should not be left in idle when loading/unloading or when parked on the site.
• Roller shutter doors should remain in the normally closed position when there is no truck loading
taking place, signage should be erected to remind employees of this.
• Reverse alarms for trucks and forklifts should not be tonal and should be replaced with a broadband
white noise reverse alarm.
• There should be no amplified music or announcements externally in the yard areas.
• Enforce 10km/hr speed limits on the grounds of the development and erect signage to indicate the
speed limits required.
• Signage should be erected in the yard and in the car park to remind workers that they are near to
residential areas and should be respectful to the company’s neighbours.
• There shall be no manufacturing works or yard activities outside of the proposed opening hours of
07:00hrs to 20:00hrs.
• Entrance/exit doors in particular those used for fire escape and emergency situations should form an
airtight seal with the door frame and surrounding building envelope when in the closed position.
Additionally, these doors should not be open when the development is in operation to protect the
amenity of the surrounding noise sensitive receptors. RECEIVED: 16/03/2026

7 Conclusion
Wave Dynamics were engaged by Fine Living Timber Frames Limited to undertake a noise impact assessment
for a planning retention application for an existing yard and change of use from retail to manufacturing facility
located at Lakeview Business Park, Castleblayney, Co. Monaghan A75A386. A request for further information
has been issued by the planning authority on the submitted application, the RFI states the following with regard to
noise:
d) Section 15.12.1 ‘Industrial and Commercial Developments within Tier 1 -4 settlements’ of the Monaghan
County Development Plan 2025-2031, states that the impact of commercial/industrial proposals on
residential amenity must be carefully assessed. Notwithstanding the findings and proposed mitigation
measures contained in the submitted noise assessment, the Planning Authority has concerns that the
proposed development would adversely affect the amenity of neighbouring residents due to the nature
of operations proposed, the sites proximity to nearest noise sensitive locations, the proposed 24 -hour
operating hours and the proposed hours of delivery. The Planning Authority is of the opinion that
operations and deliveries should be restricted to the hours of 07:00 hours to 20:00 hours, in the interests
of safeguarding local residential amenity. Having regard to same, the applicant is requested to submit
amended proposals, including an updated noise assessment, to reflect same.
e) It is noted that there is a discrepancy within the submitted noise assessment in terms of the proposed
hours of delivery i.e. page 3, 11, and 14 refer to hours of delivery of between 07:00hrs and 21:00hrs,
whereas page 16 states that there will be ‘No external works or deliveries during the night-time period of
23:00hrs-07:00hrs.’ The applicant is requested to provide clarification with regard to same.
f) The Planning Authority notes that no details have been provided with regard to proposed dust
mitigation/suppression methods associated with the proposed use and internal operations. The
applicant is therefore requested to provide the following;
i. Details of any proposed dust mitigation/suppression methods.
ii. Where this includes extractor fans or other similar noise emitting plant, these should be
assessed as part of a revised noise report, and details/specifications provided.
The development consists of:
“Retention permission for an existing external yard storage building with full permission sought for a change of
use from an existing retail outlet (RB Coogan) to a timber frame manufacturing facility with ancillary office and
staff facilities; elevational changes, new signage, an extension to the existing external yard storage building, new
plant room / ancillary store, alterations to the existing car parking areas, revised boundary treatments and all
associated site development works.”
Attended and unattended noise surveys were undertaken to measure the existing noise levels in the area and
quantify the existing noise environment. This report outlines the project criteria, survey results, assessment, and
general guidance recommendations for:
• Operational noise from the proposed facility and associated activity.
Appendix A outlines a glossary of the acoustic terminology used in this report.
Noise Impact Assessment
An attended baseline survey was conducted to establish the existing noise environment and project criteria.
Based on the assumed operating hours of the facility (07:00hrs – 20:00hrs) the proposed development has the
potential to cause negative noise impact during the daytime period.
A preliminary assessment of the proposed facilities noise emissions was conducted. It was deemed to exceed
project criteria significantly and therefore mitigation measures have been recommended in this report to reduce
the predicted noise emissions from the proposed facility to suitable levels and into compliance with project RECEIVED: 16/03/2026
www.wdacoustics.com Page 21 of 22 WDA251188RP_C_01 Noise Impact Assessment
criteria. Section 5.2 outlines the mitigation strategy in full. Mitigation measures are to be implemented in full to
satisfy compliance with project criteria.
Predicted resulting daytime operational noise levels from the proposed facility and operations have been
assessed using a BS4142 assessment which predicted that there will be a low impact at all noise sensitive
receptors during the daytime period with the mitigation measures outlined in this report implemented in full. The
predicted noise levels from the development have been compared with EPA NG4 which was predicted to comply
at all noise sensitive locations.
The RFI issued by the planning authority in relation to noise emissions from proposed dust extraction for the
proposed development has been addressed in Section 5. The location and noise levels of the proposed dust
suppression system have been factored into the assessment and deemed to not cause any additional noise
impact at the surrounding noise sensitive receptors. The extraction/suppression system does not feat ure any
external fans based on the information provided by the client and design team.
Based on the assessment and recommendations outlined in this report it is predicted that noise levels at
the proposed facility will comply with the project criteria, mitigation measures are to be incorporated in
full.RECEIVED: 16/03/2026
