Can you hear the sound produced by sonar devices?

Sonar devices emit sound waves at frequencies that are typically beyond the range of human hearing, especially in the case of high-frequency sonar used for detailed imaging. However, some low-frequency sonar sounds can be audible to humans, particularly in certain conditions. The effectiveness of sonar relies on the reflection of these sound waves off objects underwater, which is then processed to provide information about the environment. Thus, while some sonar sounds may be heard, most are not audible to the human ear.
