SOUND COLLECTOR AND HEARING IMPROVING DEVICE USING THIS

摘要

Issue: In view of a fact that an auricle has directivity characteristics of reinforcing and collecting a sound wave signal from a specific direction and in a specific frequency band higher than that of an audible sound wave signal, it is now possible to collect a sound wave having directivity characteristics similar to those of a sound wave actually collected by an auricle. Solution: A signal converter (30) converts a sound wave signal in an audible frequency band applied from a sound collecting port (31) into an electric signal; and a specific sound wave signal sound collecting means (32) collects a sound wave signal that is in a specific frequency band higher than a voice frequency band contained in a sound wave signal and can be identified in a specific direction, and the collected sound wave signal is applied to the signal converter (30); whereby the directivity sensitivity of a sound wave signal, at a frequency included in a sound wave signal and identifiable in upward and downward directions and from a specific direction, is reinforced.
