見積もり依頼

Type 4971-H-041 is designed to be accurate, reliable and robust. Its wide frequency range (5 Hz to 20 kHz, ±2 dB), wide dynamic range (20 dB(A) to 146 dB) and immunity to changing environmental conditions make it the go-to microphone for pressure-field measurements. 

USE SCENARIOS

  • Measurements very close to sound ports of an audio device (near field)
  • Measurements very close to hard reflective surfaces
  • Measurements in acoustic chambers and test boxes where reflections occur
  • Flush mounting
  • Inside an acoustic coupler (pressure field)
  • Acoustic measurements requiring a robust and reliable ½-inch pressure-field microphone operating at temperatures up to 125°C (257°F)
  • Random incidence measurements
  • Free-field measurements with 90° incidence

THIS MICROPHONE SET IS A COMBINATION OF:

The microphone cartridge and preamplifier are sealed together and are considered as one unit with a single type and serial number stored in the TEDS chip.
