5Khz-12khz Low Frequency Sound Source Overflow Ring FFR Projector

Measurement Contents:

1. Conductivity and Capacitance Curves:

Measuring the conductivity and capacitance curves of the transducer.

2. Transmitting Response: Measuring the voltage transmission response of the transducer from 5kHz to 12kHz, with a minimum of 144dB at 8kHz.

3. Source Level: The source level at the transducer's resonant frequency should be no less than 195dB.

4. Horizontal Directivity: Omnidirectional, measured at 8kHz.

5. Vertical Directivity: Half-space, measured at 8kHz.

6. Hydrostatic Pressure: 60MPa.

7. Measurement Data: Two transducers were used. The measurement acoustic performance is as follows:
