4953 1/2-Inch Pressure-Field Microphone

4953 1/2-Inch Pressure-Field Microphone

This high sensitivity microphone is optimised for pressure-field response as required in applications such as coupler measurements. A good diffuse-field response also makes it well-suited for in-cabin noise measurements up to 10 kHz.


  • 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
