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.

Angebot anfordern

This 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.
