👉 Hydroacoustic is a type of sound wave that travels through water. It is generated by the vibrations of water molecules, such as the movement of air bubbles or the oscillation of small particles like pollen grains in the air, and can be used for various applications such as environmental monitoring, navigation, and communication. In hydroacoustic systems, waves are transmitted through a medium such as water, which is known as the acoustic medium. The frequency of the wave depends on its length and width,
