3C40.10reverberation timePIRA 500
3C40.10room reverberation timeAJP 48(1),32Go around and record pistol shots in various rooms, then determine reverberation time at different frequencies with some equipment in the classroom.
3C40.10reverberation time19-4.14Students clap hands to generate sound for reverberation time.
3C40.10reverberation time19-4.13Study the reverberation time of a room.
3C40.10reverberation timeS-146Measure reverberation time of the classroom with a dB meter. (-60dB)
3C40.11reverberation tubeS-147Measure the time required for sound to die in a tube that can be fitted with caps of various materials.
3C40.20ripple tank acousticsS-148Cross sectional models of various auditoriums are used in a ripple tank to show scattering and reflection.
