A young girl with a normal audiogram and an audible clicking ear sound was seen. The sound was recorded, analyzed by oscilloscopic methods and found to be of a ringing pattern with a pulse lasting about 4 milliseconds and having a pulse frequency of one to two per second, averaging about 1.8/sec. The sound was abated by the use of a tranquilizer and the patient has returned to normal. A possible explanation of the noise mechanism is suggested, and it is hoped that the oscilloscopic analysis of recordable ear noises as employed in this case will be undertaken by other otolaryngologists so that eventually enough data will be assembled to give us a better understanding of the etiology of these sounds.
