Its the most common type of sound system used in homes. It consists of a Sub-Woofer for bass effect and 2 speakers to produce a surround sound.
Sonar.
Sound (and vibration) are a wave system of sequential compressions and rarefactions of a material. These waves are mechanical and do need a substance through which to travel. They cannot travel through a vacuum.
A Hydrophone, which is a waterproofed microphone, is used to detect sound waves in the water. This passive system was used to listen for enemy ships and submarines.SONAR was used as an active system, in quite the same way as radar, emitting a pulse of sound, and listening for the return echo. Naturally you will let the enemy know you are there!
you would still hear the sound because of the sound's echo
