Measure Extremely Low Amplitudes with PCB Model 378A08
The new 378A08 offers the lowest noise floor (25 dBA) specification within our smallest ¼" (6mm) diameter microphone series. The low profile, prepolarized microphone is matched with a preamplifier system.
The 378A08 is a free-field (FF) microphone which is capable of being used in multiple fields: free-field, diffuse field (also called random incidence), and pressure fields, more accurately than a larger sized sensor.
Applications:
- Electric automobile testing
- Component tests
- Cabin noise tests for automotive and aerospace
- Computer fan or disk drive noise
- White goods noise
- General low noise tests requiring a small profile sensor
