      25kHz Receiving Transmitting Acoustic Transducer for Acoustical Research




Measurement content:

1. Conductance and susceptance curve

Measure the conductance and susceptance parameters of the transducer in the frequency band of 15kHz~40kHz.

2. Transmitting response

Measure the transmitting response of the transducer in the frequency band of 15kHz~40kHz.

3. Receiving sensitivity

Measure the receiving sensitivity of the transducer in the frequency band of 15kHz~40kHz.

4. Directivity

Measure the horizontal omnidirectional of the transducer at 25kHz, and the vertical opening angle shall not be less than 60°.

5. Hydrostatic pressure test

The hydrostatic pressure resistance of the transducer shall not be less than 1Mpa.
