4942-H-041 Diffuse-field Microphone with 1706 preamplifier

TYPE 4942

½-INCH DIFFUSE-FIELD MICROPHONE, PREPOLARIZED

Diffuse-field microphone cartridge specifically designed for random-incidence (diffuse-field) measurements over 6 Hz TO 16 kHz, and provides noise measurement in accordance with ANSI standards.

Code Polarization Freq. range (low) Freq. range (high) Dyn. range (low) Dyn. range (high) Higher operating temperature Higher operating temperature
-4942-B-001- Classical 6.3 Hz 16 kHz 15.2 dB 146 dB 80 °C 176 °F
-4942-A-021- CCLD 20 Hz 16 kHz 18 dB 134 dB 80 °C 176 °F
-4942-L-001- Classical 6.3 Hz 16 kHz 15.2 dB 146 dB 80 °C 176 °F
-4942-C-001- Classical 6.3 Hz 16 kHz 15.2 dB 146 dB 125 °C 257 °F
-4942-A-031- CCLD 6.3 Hz 16 kHz 18 dB 130 dB 80 °C 176 °F
-4942-H-041- Classical 6.3 Hz 20 kHz 18 dB 134 dB 80 °C 176 °F

Prepolarized diffuse-field ½-inch microphone Type 4942 is optimised for general random-incidence measurements and for standardised noise measurements in accordance with ANSI standards. And being prepolarized it can connect to CCLD input conditioning.

  • Diffuse-field measurements
  • In-car measurements
  • High humidity conditions
