​What Are Hydrophones?

Hydrophones are underwater microphones that detect and measure acoustic signals in marine environments. They are essential for capturing underwater sounds, including marine life vocalizations, ship noise, and other acoustic signals. Hydrophones play a crucial role in environmental monitoring, underwater research, and defense applications. 

What are Transducers?

Transducers convert electrical signals into sound waves (transmit) or convert received acoustic waves into electrical signals (receive). They are vital for sonar systems, underwater communication, and navigation. Transducers are widely used in oceanography, subsea exploration, and industrial applications requiring precise acoustic signal transmission and reception. 

How do Hydrophones work?

Hydrophones work by using piezoelectric materials that generate an electrical charge when subjected to pressure changes from underwater sound waves. This allows them to detect and analyze acoustic signals with high sensitivity. 

How do Transducers work?

Transducers operate by sending out sound waves and listening for their return after bouncing off underwater objects. This process enables sonar imaging, depth measurement, and object detection in marine environments. ​
