Type 4953 Microphone Cartridge

TYPE 4953

½-INCH 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.

Code Standard Sound field Polarization voltage Sensitivity Lower limiting frequency Higher limiting frequency Inherent noise Upper limiting of dynamic range Diameter Venting Lower operating temperature Higher operating temperature Lower operating temperature Higher operating temperature
-4953--- ANSI S1.4 Pressure field 0V 50 mV/Pa 3 Hz 10 kHz 16 db_a 146 dB 1/2 inch Rear -30 °C 150 °C -22 °F 302 °F

This high sensitivity pressure-field microphone optimised for pressure-field response as required in applications such as coupler measurements, or close to hard surfaces.

  • 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
