Active sonar systems used by naval vessels can generate sound pressure levels exceeding 235 decibels (dB) referenced to 1 micropascal (µPa) at 1 meter. Acoustic location in air was used before radar. In an active sonar system the source also acts as a receiver. From the claustrophobic ambiance of underwater operations to the distinctive ping of sonar, these sounds add a layer of realism and intrigue to nautical content.
