  • new Acoustic solutions for wall, ceiling and furniture and

Content of talk:

Room Acoustics versus Building Acoustics

1.Noise gets blocked from one room to another

2.Noise is reflected within one room

Noise Frequencies

Wave length

Reverberation time / Echo

Reverberation time (Examples)

Church:   4 - 8 sec.

Public swimming pool:   1.7 sec.

Concert hall with classic music:   1.5 sec.

Classroom in school:   0.6 sec.

Conference room:   0.8 to 1.2 sec.

Office room:   0.5 to 0.8 sec.

The problem of Echo (Reverberation time)

Sorry, what did you say?

I could not understand.

Please repeat.

Please speak louder *********

Reverberation time and personal impression

Low frequencies too long + high frequencies to long:  Washed out and bad to understand

Low frequencies too long + high frequencies to short:   Dull, droning, but good to understand

Low frequencies too short + high frequencies to long:   Shrill, clanking, pointed, bad to understand

Low frequencies too short + high frequencies to short:   Dry but good to understand
