Auditorium Acoustics

The requirement for the intelligibility and clarity of sound within an internal space is one which is commonly overlooked. From performance spaces, airport terminals to office spaces, it is important to design rooms with acoustic performance in mind so that speech, music, and emergency address can be deemed clear and intelligible.

Typical noise metrics used in order to predict the acoustic performance of an internal space include:

  • Reverberation time of a room
  • The Clarity Index (ratio of early to late sound reflections)
  • Listener envelopment
  • Speech Transmission Index

Room acoustic parameter modelling and prediction

With the use of complex ray tracing software, it is possible to predict room acoustic noise metrics and listener aspects prior to the construction of a space. This is an indispensable tool as performance spaces, emergency personal address systems, and critical listening spaces can be accurately modelled in order for the final built product to perform exactly as it is intended. Full auralisation of an acoustically modelled space makes it possible to listen to how a room will sound prior to its construction.

Retrofitting and verification of acoustic performance

Existing listening spaces like restaurants, bars, studios, halls and the likes can be acoustically modelled in order to treat and improve the acoustic performance of that space. Making use of specialized software and noise data acquird from talking noise level measurements, it is possible to model an existing space with a Computer-Aided Design program and compare actual measurements within the space. Once the model is calibrated, acoustic treatments can be considered.

Great service and excellent acoustic report from Koikas Acoustics. James who attended our site was really efficient, professional and friendly. James brought along a variety of premade flooring samples, so we had a lot of confidence in the outcomes, which enabled us to select the correct sound proofing mix to meet our acoustic by-laws. Highly recommended.

I am a project manager at DMC Building Group. We are a renovation company that works in the Sydney region. We recently engaged Koikas Acoustics to prepare a report for us in relation to a unit renovation at Lindfield to address the concerns of the body corporate. The service from Nick and his team was outstanding and the report was prepared and delivered on time and on budget. We could not be happier with their service. Highly recommended.
