Acoustic characteristics of chair suited to the hall application

Data was compiled on the types of chairs suitable for use in accordance with "JIS A 1406 Method of Measuring Reverberant Absorption Coefficient". Based on our rest data, the sound absorption power characteristics per chair are described.

Chairs suited to concert halls

There is most no sound absorption difference when the seat is unoccupied and optimal rehearsals can be carried out without being affected by the size of audience. Overall, the sound absorption power is small. The wooden back medium absorbs the low tone range while the audience absorbs the medium and high tone range, thus delivering a well-balanced, pleasant sound.

Chairs suited to movie theatres

In movie theatres, the sound field and sound effects are designed in advance according to the sound produced by speakers of the theatre. For the reason, adjustment are made within theatres to eliminate excessive reverberation, therefore chairs that do not overly reflect sound and that raises the sound absorption power are required.
