Calibration for Impulse Response Measurements, by G. Koutsouris and C.L. Christensen
This is a guide on how to calibrate the ODEON measuring system in order to obtain the Sound Strength (G) and Speech Transmission Index (STI) parameters. Calibration should be performed in a diffuse or an anechoic chamber. On top of that, a two-step calibration procedure is developed, which ensures that any change in the equipment gains does not destroy the calibration.
