Uittreksel

One of the parameters for an objective measurement of the acoustical spaciousness in a room is the IACC. According to ISO 3382-1 this parameter must be measured using a head and torso simulator (HATS). According to the same standard, all other room acoustical parameters (related to loudness, reverberation, clarity and speech intelligibility) must be measured using an omnidirectional microphone. The feasibility was investigated of using a HATS to measure, in addition to the IACC, other parameters given in ISO 3382-1. Room acoustical parameters measured with a HATS were compared with the same parameters measured with an omnidirectional microphone. Here the HATS was rotated around its vertical axis in steps of 10 degrees, where at each step a measurement was performed. The main result is a set of polar diagrams in which all measured parameters display a clear directivity. Angle-independent single-number quantities obtained through averaging are partially comparable to those from omnidirectional measurements.
