Redevelopment of Town Centre Hotel
Redevelopment of Town Centre Hotel
August 2018
Noise surveys were undertaken at this former Town Centre Hotel site. External ambient sound measurements were measured and recorded for 24 hours at both the front and the rear elevations. The results of the survey determined the existing noise conditions at the site. The noise report assessed the impact on the future and existing occupiers in accordance with WHO guidelines and noise criteria set out in BS 8233:2014. The overall conclusion of the noise report was that there would be no adverse impact from noise on the residential amenity of intended occupiers or from the proposed restaurant use.

Noise Surveys
Outdoors concerts
Outdoors concerts
August 2018
Licensing Authorities require live outdoor music concerts to strictly adhere to preset noise limits specified in the licence. Compliance noise monitoring requires a sound to fix the sound levels at the mixer desk and at agreed monitoring points. For the duration of the concert there is continuous simultaneous monitoring of the sound levels by the deployment of audio and acoustic analysers at the mixer desk and at positions on the boundary of the venue in close proximity to noise sensitive residential dwellings. The monitoring aims to demonstrates whether or not the sound limits imposed by the Licensing Authority are compliant throughout the duration of the concert.

Noise Surveys
Car wash
Car wash
October 2017
The noise assessment considered the likely impacts of noise arising from the operation of the hand car washing facility and any additional equipment to be used together with its proximity to neighbouring potential noise sensitive residential buildings and the impact on amenity. The design of the outdoor hand car washing facility would ensure it would operate to a rating level at least 6 dB below the lowest measured daytime background noise and meet the Council’s noise criterion.

Craft beer shop
Craft beer shop
July 2017
Noise surveys of the existing conditions at the site on a weekday and over a weekend were carried out to record background and ambient noise levels. The air conditioning units were required to operate to a level at least 10 dB below the lowest measured background noise when under actual operating conditions with a noise mitigation strategy in place. The design of an acoustic enclosure of the outdoor units ensured that operational noise levels of the units would meet the Local Planning Authority noise criterion when measured outside the nearest window of the nearest residential property whilst also having regard to the context of the site and its permitted use.

Noise Prediction
Proposed new industrial site
Proposed new industrial site
June 2017
A noise survey of existing sound levels at the application site was undertaken in 2016. As there had been no change in the use of the units on the adjoining Business Park and other nearby commercial premises in 2017 it was considered that the baseline survey represented the noise conditions in 2017. As vehicles would be leaving the site from 5am it was arranged to carry out an additional measurements of the sound levels generated by a number of haulage vehicle start ups, parking and movements on an early weekday morning on the existing southern perimeter road. Calculations enabled the prediction of the noise levels generated from operational conditions and its effect on the closest noise sensitive residential properties to the application site. Results of the monitoring exercise and assessment in accordance with BS 4142:2014 established that no adverse impact on the amenity of neighbouring residential properties would result.

Effectiveness of windows
Effectiveness of windows
August 2016
Surveys of external and internal sound levels were carried out during night time hours on a weekend for the reason that the owners complained that the greatest level of disturbance occurred at these times from nearby late-night restaurants, bars and night clubs. The surveys entailed simultaneous measurement of sound levels on a balcony and measurement of sound levels inside the living rooms. The sound levels including high peak events occurred regularly from midnight up to the terminal hour of the licensed premises some of which were are open to 03:30 hours. The average noise level inside the flat was above the sound levels in BS 8233:2014 which are designed to ensure reasonable resting/sleeping conditions in bedrooms and good listening conditions in other rooms. In conclusion, the design of the façade should have taken into account night time external sound levels generated by the licensed premises and a higher specification for replacement glazing was recommended.
