Design and Measurement of Short Reverberation Times at Low Frequencies in Talk Studios
Various types of acoustic treatment have been used in the new talks studios of the Danish Broadcasting Corporation. For verification, reverberation times around 0.1-0.2s were measured in 1/3-octave bands from 80Hz to 8kHz using a new, time reversed analysis technique. It is demonstrated that the ringing of the filters would have introduced errors at low frequencies, if traditional forward analysis had been used.
