The quality of the built environment is highly influenced by the acoustical characteristics of the building materials and internal surfaces. Whether these are habitable or non-habitable rooms, open plan or focused work areas, waiting rooms and lounges, shops or display rooms, conference and function rooms; appropriate management of the sounds that are audible inside a building is the key to effective design for a suitable comfort profile.
Building acoustics applies the science of sound transmission through building elements to estimate recommended materials that will provide reasonable comfort for the specific purpose. For example, the construction of internal party walls between residential apartments in Australia (by the National Construction Code) must be built with a standard such that noise reduction from one side of the wall to the other allows a person to conduct everyday life activities without being heard on the other side. Furthermore, noise from freeways, railways or aircrafts taking-off or landing shall also be appropriately reduced by house windows, doors, roofs and other elements. These concepts are also fundamental in the fit-out of corporative offices where the levels of privacy inside meeting rooms is important or in the educational field where acceptable noise levels are pivotal for effective focus and learning.
Services covered in this area include:
- National Construction Code (NCC) acoustic reviews for residential development
- Assessment of building services noise and vibration
- Testing and measurements of sound transmission loss through building elements, reverberation time and structure borne noise
