Reverberation Time

Multi-Channel Instrument + SAMURAI Software by SINUS Messtechnik GmbH + Microphone


Reverberation time measurements may be conducted using any multi-channel instrument plus SAMURAI acoustic software by SINUS Messtechnik GmbH and a single microphone (Note”Reverberation times can also be measured simultaneously at multiple locations, if desired).

Suitable multi-channel instruments include the SoundBook, NoisePAD, or Apollo/Apollo Lite Boxes plus laptop, or a PCIe Card plus PC.

The sound field of the room may be excited by impulse, interrupted noise or swept sine wave using the SAMURAI Signal Generator Software Option to provide output from the multi-channel instrument to the sound source, or by some other external means.

Measurements may be conducted using the single microphone at multiple microphone positions with various source locations, in accordance with the methods of ISO 3382, Parts 1 and 2, ISO 354 and AS/NZS 2460:2002.

The user can select one or more averaging of reverberation measurement data per receiver position to suit the standard or test process.

Reverberation may be measured and displayed as Early Decay Time (EDT), RT15, RT20, RT30 with backward or forward integration of the decay curves, as preferred.

Typical Reverberation Set-up and Output windows from SAMURAI software are shown below:
