ABSTRACT:
A sound recording and reproduction system for testing hearing and hearing aids is disclosed. Recordings of sound are made in a real word acoustic environment, for example, which are stored as audio signals. In a testing environment, a plurality of loudspeakers is located about a listening position where a test subject is placed during a testing procedure. The plurality of loudspeakers receive at least a portion of the plurality of the stored audio signals, and convert those audio signals received into a combination of sounds that produce, at the listening position, acoustic elements of the real world acoustic environment where the recordings were made. The system enables, in a clinical or other test setting, the evaluation of hearing and/or hearing aid performance as if in a real world environment.
