In small mics like MM, SP or CC, what exactly is the acoustic mesh?
Thanks in advance ;)

No responses so far.
I guess this is a dumb question.
Well, it's not. It's just a matter of language: English is not my primary language.
Any good soul out there?

acoustic mesh might be the material covering the actual microphone capsule
it looks like a fine wire screen; usually flat round or shaped into a sphere

Thanks a lot, friend.

The term 'mesh' seems confusing as most small commercial lapel type mics have a outside metal cap with drilled holes, and sometimes actual wire screen.
However inside covering the capsule's sound hole is sometimes a fine felt material keeping dust and other contaminates from easy access to the diaphragm.

Thanks Guysonic. +T for your help.
I own a HLSC-1 pair and just like to know. In the HLSC-1 there's a metalic thin material protecting the air vents. I was thinking that this material was actually the acoustic mesh.

When the "acoustic mesh" is metallic, it often serves as a necessary electrostatic shield for the capsule. Some people who "hot-rod" (custom modify) professional microphones like to remove one or more layers of screening because they imagine that to do so will "open up" the high frequency response of the capsule. The intuitive image is a strong one, but things don't work quite that way in most of the range of a pressure gradient capsule--and such modifications can make the microphone very sensitive to radio frequency interference. So in case that was the motive behind these questions, please be careful, and have a "plan B" for when your "plan A" has unexpected results.

Thanks a lot, DSatz. +T
You're the man ;)
