Acoustic Modem Application:
An acoustic modem is used to transmit data underwater, much as telephone modems are used to transmit data over phone lines. An acoustic modem converts digital data into special underwater sound signals. These signals are then received by a second acoustic modem and converted back into digital data. Acoustic modems can be used for underwater telemetry, ROV and AUV command and control, diver communications, underwater monitoring and data logging, and other applications requiring underwater wireless communications.
A transducer that converts sound signals into electrical signals is used to receive sound signals in water. It is called areceiving transducer, also known as a hydrophone. Hydrophone is widely used in underwater communication, continental exploration, target location, tracking and so on. It is an important component of sonar. Underwater detection, identification, communication, marine environmental monitoring side and marine resources development are inseparable from underwater acoustic transducer.

PZT Material:
- PZT4 Piezoelectric ceramics have a double behavior of receiving and transmitting, with higher sensitivity and lower dielectric loss.
- PZT5 Piezoelectric ceramics have higher electro-mechanical coupling coefficient, the moderate dielectric constant and higher sensitivity.
- PZT8 Piezoelectric ceramics of high power transmission type have good piezoelectric property, high mechanical strength, high coercive field, low dielectric loss in strong fields.
