I'am searching for low priced micrphone capsule (< 10$) for a simple sound level measuring. It should be able to measure levels between 30dB(A) and 90dB(A).
I have already searched for manufacturers, but I have only found cheap capsule. With those capsule I'am not able to measure 30dB. Thera ist mor noise then signal.
Do amnybody knows a manufacture for suitable mics ?
I would be very happy.
