¼" Free-field microphone Type 40BF - High-level

The Type 40BF is a ¼" microphone for high level and high frequency measurements. Its low sensitivity makes it ideal for measuring very high sound pressure levels; up to 174 dB re. 20µPa. Its small size reduces disturbances in the sound field; resulting in a frequency range reaching up to 100 kHz.

Can be used with  ¼" Preamplifier Types 26AC and 26TC.

The following applies only to ¼" microphones:
For most applications, rear venting is more advantageous particularly where phase response is critical. However, if front venting is preferred, please add "front venting" to the Type number of the microphone when ordering.
