Room acoustic descriptors – RT, C50 and Strength/ Gain

Reverberation (RT) time still remains the primary indicator of room acoustic response and RT is also known to be the only demand/descriptor in building regulations for room acoustics in healthcare facilities, schools and day care centres and offices. However, previous work and research for many years has shown that RT alone can be insufficient to […]

Input data – how do we predict room acoustics?

Calculation tools Recently a new acoustic calculation tool has been published. It is based on Air Flow Resistance (AFR) and calculates several room acoustic descriptors. This article aims to explain why calculations based on the Sabine equation are not always the whole truth. Background – Sabine and ISO 3382-1/2 A long tradition of research shows […]
