Services: Noise Consultants in Kent

Here you can view examples of the capabilities of our noise consultants and some of the services we provide.

Noise & Vibration Monitoring

We supply attended and unattended noise & vibration monitoring options from a range of audio enabled Class 1 sound level meters and tri-axial vibration monitors fitted with GSM modems for trigger alerts & remote access.

We use start of the art, reliable and accurate Vibra+ and Rion equipment for sound and vibration measurement. The units can be set to send alerts to your smart phone should a preset limit be exceeded, they can also be set up to remotely email a report of monitored levels every 24 hours.

Acoustic Assessments & Planning

Planning authorities may require a noise/vibration assessment as part of the planning process. We advise applicants, agents and authorities on noise in the context of relevant policy across England & Wales.

Able Acoustics’ noise consultants provide detailed yet clear Acoustic Reports/Noise Reports in support of Planning Applications and the discharge of conditions for BS8233 and BS4142.

Acoustic Software Modelling

Software modelling allows the user to evaluate a variety of calculation-based options for a range of theoretical scenarios. Our extensive library of calculation software allows us to identify any mitigation requirements quickly and in detail.

Able Acoustics: Noise Modelling. Our noise consultants have almost 20 years experience using the expert industry software package SoundPLAN and have also previously provided product support for the specialist building acoustics software (Insul) that we still use to this day.

Acoustic Design of Buildings

The design of rooms for specific uses is driven by an understanding sound will behave in a space based on its geometry and the absorptive effects of the different surfaces.

Building Acoustics is the field of acoustics concerned with how to control sound to meet the requirements of the intended environment using ‘reflection’ to focus the sound in a certain direction and ‘absorption’ to dissipate a proportion of the sound.

Additionally, the control of the onward transmission may be relevant, which is typically controlled by mass to provide ‘insulation’ and through ‘isolation’ to introduce discontinuities into the transmission path.

Construction Noise & Vibration

Noise from construction and demolition sites can give rise to complaint which can be avoided by calculating the cumulative levels from multiple sources and applying suitable mitigation.

Construction Noise Management: Section 61 of the Control of Pollution Act 1974 allows a contractor to apply to the local authority for prior consent to carry out construction or demolition works. The application will contain details of the work to be carried out, the hours of any works and details of measures to reduce the noise from the work.

A ‘Section 61’ offers the applicant protection from subsequent action by the local authority to impose further controls on noise from the site. Other benefits are fewer ‘unexpected complications’ and any concerns over noise/vibration can be identified and controlled in advance. This also provides a way of managing the work’s programme and site resources more effectively.

Occupational Noise Exposure

Occupational Noise Exposure

The Control of Noise at Work Regulations place a series of duties on employers and employees designed to ensure legal limits on exposure are not exceeded.

Workplace Noise Assessments are sometimes required where employees are routinely exposed to noise as part of their day to day work. Prolonged exposure to noise can lead to noise induced hearing loss for which there is no cure.

By considering the levels from the different processed and operations it is possible to introduce mitigation measures to reduce exposure as well as identify any areas where personal hearing protection (PHP) might be required and the suitability of the different types of PHP available.



BREEAM (BRE-Environmental Assessment Method) is a credit-based assessment system for new and existing buildings which may be used for education, healthcare, residential & non-residential use (such as office, industrial & court buildings).

BREEAM acoustic assessments fall under HEA 05 Acoustic
Performance (where credits are achieved for minimising disturbances to building occupants from noise transition between spaces & providing an appropriate acoustic environment for the different functions of various spaces) and POL 05 Reduction of Noise Pollution (where credits are achieved for reducing the likelihood of noise from fixed installations on the new development affecting nearby noise-sensitive buildings).

Transportation Noise

Transportation Noise

The primary noise source affecting residential premises in the UK is transport noise which is considered where a new scheme is proposed or new development is to be located nearby.

The Noise Insulation Regulations 1975 set out the criteria for buildings to qualify for statutory or discretionary noise insulation.

These are the Prevailing Noise Level one metre in front of the exposed windows/doors in a facade of a building attributable to traffic prior to construction, the Relevant Noise Level at one metre in front of exposed windows/doors in a facade of a building attributable to traffic using the new/altered tranport system and the level of increase above the prevailing noise level.

Entertainment Noise

Noise control for concerts involves setting limits and carrying out sound propagation tests prior to the event so levels can be set & controlled from the Front of House.

To prevent live music from causing a statutory nuisance, Music Noise Levels (MNLs) have to be managed correctly. These can be calculated prior to the event or measured during sound check by generating a signal at the desk and increasing the volume until it reaches the guideline value at noise sensitive premises.

During the event measurements can be taken at the desk to ensure pre-agreed levels are not exceeded. Some of the concerts our noise consultants have worked at include Glastonbury, Hyde Park Concerts and the former Earls Court Exhibition Centre.

Ground & Structureborne Vibration

Ground & Structureborne Vibration

Sound is a form of vibration, although vibration is usually interpreted as being either groundborne or structureborne. Vibration may also be re-radiated as audible sound.

Reference to vibration is generally taken to mean ground or structure-borne vibration. Vibration is measured in terms of Velocity, Acceleration, Displacement and Frequency.

Understanding how these parameters are interpreted allows us to calculate human exposure, the levels at different locations inside buildings, the effect of vibration on building structures and in some cases how much is re-radiated as sound.

Noise Control Engineering

Noise Control Engineering

Noise Control Engineering is concerned with limiting the level of sound transmitted by a source by taking into account the mechanisms by which it is produced and transmitted.

Noise Control Engineering relates to the mechanisms by which a sound is produced and the transmission path, these could be aerodynamic sound sources from ventilation fans and ducting or radiating surfaces from machinery.

By applying engineering principles such introducing pressure changes (bends, branches or plenum chambers) to duct runs, destructive interference between sound pressure waves in the form of active noise control or simply isolating machinery from the supporting structure the overall level of sound transmitted by a source can be controlled.

Industrial Sound & BS 4142:2014

Commercial/industrial noise is assessed using BS:4142, for the purpose of investigating complaints, or where industrial/commercial sound may impact new or existing dwellings.

The latest version of the standard (BS4142:2014+A1:2019) is approximately 4 times the sizes of the previous edition requiring more information to be reported and considered in particular the ‘context’ in which a sound occurs.

The standard is applicable to sound from industrial and manufacturing processes, fixed installations, the loading and unloading of goods and sound from mobile plant and vehicles such as forklifts.

Our noise consultants have been commissioned to sit on the panel with other industry professionals at training events for Environmental Health Officers and legal professionals explaining the use of the standard and its practical applications/limitations.
