Acoustic modems

Acoustic modems are devices that enable underwater communication by converting digital data into sound waves, which travel through water. They work similarly to radio modems used on land but are specifically designed for the challenges of underwater environments, such as limited bandwidth and signal attenuation. These modems are used in applications like ocean exploration, underwater research, and submarine communication, allowing reliable data transmission over distances underwater where radio waves are ineffective. They typically consist of a transmitter and receiver that encode and decode data into acoustic signals, ensuring information can be sent and received between submerged systems and surface or remote locations.
