I can provide you with information on submarine SONAR pings.

SONAR (Sound Navigation And Ranging) is a technology used for detecting objects underwater by emitting sound waves and listening to the echoes that bounce back. The active SONAR system on a submarine emits short pulses of sound, known as pings, into the water. These pings travel through the water and interact with objects in their path. When the sound waves encounter an object, they bounce back to the submarine and are detected by hydrophones (underwater microphones) on the submarine.

The hydrophones onboard the submarine are specifically designed to detect the echoes of the SONAR pings. They can pick up and analyze the returning sound waves to determine the presence, distance, and other characteristics of underwater objects or features. This information is crucial for navigation, detecting other vessels or submarines, and gathering intelligence.

It's important to note that human ears cannot hear the frequencies typically used in SONAR systems, as they operate in the ultrasonic range. These frequencies are beyond the hearing capabilities of most marine mammals as well. However, there are other species, such as certain types of dolphins and whales, that can detect and respond to SONAR signals.

So, while we cannot hear SONAR pings directly, submarines and specialized marine life have the ability to detect and interpret these sounds in their respective contexts.
