GRAS 46AN 1/2'' LEMO Free-field Standard Measurement Microphone Set, Low Frequency

The GRAS 46AN is a 1/2" Traditional Power (LEMO) freefield microphone set for measuring medium sound pressure levels at low frequencies. It is terminated with a 7-pin LEMO connector and is TEDS compatible.

The 46AN is a free-field microphone set and as such optimized for all acoustic applications, where the location of the main sound source is known and the microphone can be pointed directly at it ensuring 0° incidence. The low frequency makes it ideal for measuring low frequency sound from e.g. wind mills.

Freq range (±3 dB): 0.5 Hz to 20 kHz
Dyn range: 17 dB(A) to 149 dB
Sensitivity: 50 mV/Pa
Use: For low frequency acoustic diagnostics
