Windbreak layer with the surface sound pressure measurement microphone

摘要

PROBLEM TO BE SOLVED: To reduce (so-called lossless) wind noise without changing the sound quality and spectrum structure of measured sound, by blocking the generation and propagation paths of wind noise entirely and rationally.SOLUTION: A surface sound pressure measurement microphone 100 with windbreak layer for measuring the surface sound pressure of a mobile includes a microphone 10, a first windbreak layer 20 covering the top of the microphone 10, and a second windbreak layer 30 covering the microphone 10 entirely. The first windbreak layer 20 and second windbreak layer 30 are composed of a material having acoustic transparency, a first space layer is provided between the first windbreak layer 20 and the top of the microphone, and a second space layer is provided between the second windbreak layer 30 and the whole microphone.
