Home Cinema Seating - August 28th, 2008

Home cinema seating has its own absorption characteristics. These would have to be predicted or measured in the home cinema’s design stage. People tend to panel the whole home theatre, ending up with a very low reverberation time, making it sound “dead”. This is not how a home cinema room should sound, and the seating area needs to be taken into account, when calculating the room’s acoustic treatments.

Predicting the total absorption that the home cinema seating is going to have in the room is a very difficult process, due to the geometry of the seats. Different methods have been experimented in reverberation chambers, in order to find a tool, on how to accurately predict the absorption of the home cinema’s seating.

The acoustic result of a home cinema would vary between occupied and unoccupied seating. Home cinema seating could have a large variation of absorption, depending on the model used. The good news here is that occupied seating in a home cinema room would not vary as much, regardless the model of seating used.

By modelling the home cinema seating area as rectangular absorption material with dimensions a,b,c, we can then apply the relevant absorption coefficient. Careful selection for the rest of the room’s treatments, would allow us to design a home cinema room with a very good accuracy.
