What are Building Acoustics?

Building acoustics (also known as architectural acoustics) focuses on internal and external noise levels and how we control these to comply with the requirements of standard and guidance documents such as BS8233 and Approved Document E.

From the physical building envelope including the façade, roof, glazing and doors to the internal partition construction, building acoustics needs to be compliant to ensure that the health and well-being of the occupants is unaffected by internal and external noise.
Noise is generated by a wide range of sources, from transport using our road, rail and air traffic systems to the television playing in another room. Implementing a successful design ensures all relevant sources are taken into account at planning stage to ensure the acoustics in residential buildings, schools, healthcare and other sectors meets the expected demands.

For existing buildings the same methodology is used to design acceptable solutions of acoustical control in buildings, that can be incorporated into the existing framework of the building.

The internal aspects for acoustics is covered further in or blog post on room acoustics.

Benefits of good building acoustics

Implementing the correct acoustical control in a building helps alleviate a variety of issues including sleep deprivation, poor speech intelligibility, cognitive problems, stress, anxiety and loss of revenue.

New developments may require a noise impact assessment that is crucial in identifying existing noise levels, allowing us to design a building envelope or site layout to meet the internal noise level required.
Elements considered in achieving a successful design include:
– Façade construction
– Glazing and Doors
– Rain Noise (Roof Construction)
– Structure-borne sound
– Impact Sound (internal floors)
– Airborne Sound (walls and floors)
– Ventilation and Overheating
– Reverberation
– Noise Pollution (affects elements above as well as conditions in external areas such as gardens)
– Indoor ambient noise levels (affected by air conditioning units etc.)

Associated standards and guidance

The whole environment needs to be considered when designing or planning to build (or refurbish) buildings for any use. This includes how the existing background noise levels may impact on the future buildings and the occupants as well as how any new noise may affect those in the local vicinity. We achieve this through the use of vartious standards, design guidance and codes that are applicable tot he type of building and its use.
These include documents ssuch as:
– BS 4142:2014+A1:2019 Methods for rating and assessing industrial and commercial sound
– BS 8233:2014 – Guidance on Sound Insulation and Noise Reduction for Buildings
– Approved Documents Part E: Resistance to the passage of sound; Part F: Ventilation and Part O: Overheating
– Acoustics, Ventilation and Overheating: Residential Design Guide January 2020
– ProPG: Planning & Noise – New Residential Development, May 2017
– WHO Guidelines for Community Noise
– Calculation of Road Traffic Noise (CRTN)
– Calculation of Railways Noise (CRN)
– National Planning Policy Framework (NPPF)
– Noise Policy Statement for England (NPSE)
