Explanation / Answer

MAIN POST Sound waves under Deep Ocean: Travelling to the deep ocean is difficult because of the increase in pressure of the pushing water. But due to recent developments in technology, now people can listen to how deep water sounds. Hydrophone is a device which can record the noise that is under water and through the cable it is processed and sent. It is run live in YouTube as well. Though Hydrophones can record high pitch frequency, humans have a range from 20 Hz to 20000 Hz. The sounds which fall under this range can be listened to by opening the live YouTube video. Animals who hear this sound are different from how humans hear it. The other sounds that can be listened to are Ship’s noise, dolphin’s clicks. The principle behind the hydrograph is that sound travels wide and faster in water than in air.
