Description

Use of Pressure-field Microphones
Pressure-field microphones are optimised to have a flat frequency response in a pressure field. The microphones should be used for making measurements in small, closed couplers or close to hard, reflective surfaces. Type 4192 is suited for situations where a robust and stable pressure-field microphone is required.
