3C40.10 | reverberation time | PIRA 500 | |
3C40.10 | room reverberation time | AJP 48(1),32 | Go around and record pistol shots in various rooms, then determine reverberation time at different frequencies with some equipment in the classroom. |
3C40.10 | reverberation time | 19-4.14 | Students clap hands to generate sound for reverberation time. |
3C40.10 | reverberation time | 19-4.13 | Study the reverberation time of a room. |
3C40.10 | reverberation time | S-146 | Measure reverberation time of the classroom with a dB meter. (-60dB) |
3C40.11 | reverberation tube | S-147 | Measure the time required for sound to die in a tube that can be fitted with caps of various materials. |
3C40.20 | ripple tank acoustics | S-148 | Cross sectional models of various auditoriums are used in a ripple tank to show scattering and reflection. |
