Question

how are some sounds useful to us? explain​

Answer 1

Answer:

Ultrasound waves are used to detect objects. A ringing telephone, a honking horn, and the sound of a friend's voice are all reminders of how important sound is. But sound has uses that go beyond communication. For example, some animals and people use reflected ultrasound waves to detect objects.

Answer 2

Answer:

Sound is important because it can tell us about character, place, and time. It's important because it informs us and moves us in ways visuals can't, and because certain combinations of sound and visuals can evoke what neither can do alone. It's also potentially important because it can help to determine what we see.
