Measuring Ambient Noise in the Underwater Soundscape

Wind, waves, shipping, and marine life all contribute to a background noise field that sets the practical detection limit for any sonar or sensing system.

Because this soundscape shifts with weather, season, and location, it has to be measured in situ rather than assumed from a generic curve.

A well characterized noise floor turns raw hydrophone data into a meaningful signal-to-noise budget for system design and acceptance.
