Product Introduction
It is a dual microphone sound intensity probe designed according to GB/T 17561 and IEC 1043 standards. It includes two phase paired 1/2 "test condenser microphones and two phase paired AWA14614E preamplifiers. When combined with a sound intensity analyzer, it can measure sound intensity levels at frequencies from 45 Hz to 7.1 kHz. If you want to analyze frequencies above 7.1 kHz, you can also choose a 1/4" test condenser microphone pair.
