We think of the deep sea as an eerily quiet and spooky place but that isn’t completely true, animal communication, seismic activity, human noise and even the sound of rain and waves from 10 km above. We chat with undersea audio expert Dr David Barclay about the fascinating audio properties of the deep ocean. As we are talking audio data on an audio medium, lets have some fun with a game of ‘what can we grenad-hear’ where Thom tries to guess the deep-sea sound.
