Cavitation occurs because the propeller blade tips reduces the vapor pressure there and this turns the water into bubbles of steam. The actual sound is caused when the bubbles collapse and the they make an amazing amount of noise. The faster the prop turns the greater the noise. The noise heard through sonar is kind of like a steam locomotive "chuffing".

Cargo cha cha cha cha. Warship shhhh shhhh shhhh. Surface ship burning bush. Deep Sub squeak squeak squeak. Compressed cavitation. Soviet subs were loud as freight rains. But they could outrun our torpedoes.
