Hey there Neilep, I would say that the sound waves obviously have a different effect on the medium in which they are travelling. Seeing as though the water in non compressible, I would say that it contains the energy of the wave and transfers it better than the air, but is muffled due to the density of the medium......just thinking aloud though and have been proven wrong on quite a few occasions
I think that theoretically your thinking underwater does in fact seem louder than outside of the water due to the lack of background noise What, I am sure would be interesting for you in particular, would be to see how far a sheep's bah can travel underwater and still be heard...although I feel that the sheep might not be too keen to partake in this little experiment.
I wonder whether sound underwater is muffled because of how your ears work ... Ears filled with water may not be too good.
I wonder whether sound underwater is muffled because of how your ears work (sheep's and human's). Ears filled with water may not be too good. As I understand it water would not diminish the high frequencies and a quick read of the web suggests that sound recordings for underwater films sometimes add bubbly sounds and deliberately muffle high frequencies for effect as it is what us punters expect. A fact I just learnt was that stereo is useless in water because our ears/brains are adapted to working out the direction of a sound source in air where the wavelengths are very different. Divers can't easily tell where a sound is coming from apparently.

Ears filled with water may not be too good.Water is more dense than air and will damp the motion of the eardrum much more than air, particularly the high frequencies. This is why sound is muffled, (i.e. high frequencies are lost), when you are underwaterWith a hydrophone, a microphone specifically designed to work underwater, (unlike the human ear), the sound is not muffled. Hollywood may cut the high frequencies from a hydrophone recording so it is more similar to frequency response of the submerged human ear.
Hey Neilep, any progress on the sponsorship application for our research yet? I am preparing my PTFE liver for this adventure
