Benchmark Problems for Acoustical Parameters

Column

Easy to fall into the faults of calculation procedure are explicated in following columns:
  1. Relationship between back groundnoise and the reverberation time
  2. Reading correct reverberation time from insufficient decay length
  3. Detecting the location of direct sound
  4. Filtering first? Time Division first? –The procedure to derive energy ratio of time division and band analysis–
  5. A comparison between the design methods of digital filter and derived room acoustical index
