Test on Sound Transmission Characteristic of PTFE Micro-Aperture Membrane
: It is a test of sound transmission characteristic of PTFE Micro-aperture Membrane,through it we found that the PTFE Micro-aperture Membrane is an excellent material of sound transmission for its special structure, though the basic rule is of no difference from normal material. Something more important, from test data, it was discovered that PTFE will not affect sound transmission when aperture diameter reaches 0.22m, which is valuable for the research of sound transmission on Micro-aperture.
