TYPE 4971-H-041
1/2" CCLD Pressure Field Microphone Set with BNC Connector
CCLD Pressure-field microphone for coupler, random-incidence and free-field measurements with 90° incidence and a frequency range of 5 Hz to 20 kHz
견적 요청하기Type 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.
