A detailed examination of a case of monaural diplacusis is reported. Low-intensity pure tones presented within a certain frequency range do not sound "pure"; instead, the percept is that of "roughness", "multiple tones" or "beats". In addition, an aftertone is heard upon the cessation of certain tones. Psychophysical experiments (e.g., simultaneous masking, best beats and pitch matching) suggest that the monaural diplacusis results from an interaction between the external tone and an internal tone. The internal tone, however, does not appear to be manifest as a spontaneous oto-acoustic emission.
本文报告了一例单耳复听病例的详细检查情况。在特定频率范围内呈现的低强度纯音听起来并不“纯净”；相反，其感知为“粗糙感”、“多个音调”或“拍音”。此外，在某些音调停止后会听到余音。心理物理学实验（如同时掩蔽、最佳拍音和音高匹配）表明，单耳复听是由外部音调和内部音调之间的相互作用引起的。然而，内部音调似乎并不是以自发性耳声发射的形式表现出来。
