Abstract
The method used by the author is distinct from the usually employed procedures: In a camera silens the subject lies comfortably and relaxed on a bed. The microphone (B & K 4145) is freely suspended at the entry to the external auditory canal (Fig. 1). While the system should be very sensitive, the entire acoustic output from the auditory canal should be captured rather than a limited section of it. Although the sound-flow from the auditory canal is widened to the membrane, little energy is lost.
