ABSTRACT:
Multiple single-frequency tones are presented simultaneously to a subject by each of two transducers for the purpose of testing hearing. One transducer is employed to present a plurality of f.sub.1 primaries and the other transducer a plurality of f.sub.2 primaries so as to make the ratio of f.sub.2 to f.sub.1 sufficient to produce evoked distortion products by the pair. Proper selection of the frequencies prevents numerous intermodulation products.
