TYPE 4953
1/2" Pressure-field Microphone, Prepolarized, 3 Hz - 10 kHz
Pressure-field microphone designed for coupler measurements and in-cabin measurements (complying to ANSI standards) over a frequency range of 3 Hz to 10 kHz.
Request PriceThis high sensitivity pressure-field microphone optimised for pressure-field response as required in applications such as coupler measurements, or close to hard surfaces.
USE SCENARIOS
- Coupler measurements
- Hearing aid testing
- Telephone testing
- In-cabin measurements
- Measurements to ANSI standards
- Measurements to be made close to hard reflective surfaces or inside closed couplers
- High humidity environments
The frequency response of Type 4953 has been carefully designed in such a way that this microphone also has a good random incidence response, making it suitable for in-cabin noise measurements up to 10 kHz, for instance in the automotive industry.
