Utility
Characterization of reverberation of audible spaces
11 Oct 22
A method and system for improving the intelligibility of an audio signal emitted from plural audio output devices in a space can help mitigate systems that have low intelligibility at installation due to reverberation effects; it can provide a quick post installation check of a system prior to a full-fledged STIPA (Speech Transmission Index for Public Address Systems) or equivalent test; and it allows for a quick verification if changes to the acoustical environment are expected to have major effects on STIPA tests.
