Audio through liquid

[LERsince1991]

Hi, I'm thinking of designing something which would bring something new to the audiophile end of the audio market, its a completely conceptual project though.

Would anyone be able to say whether audio is 'better' though a liquid, fluid or water.

Also why could it be better?
I seem to remember someone saying to me that they installed a set of speakers in a swimming pool once and the sound was out of this world.

Any info you could provide would help me.

Thanks!
Luke.

Takes a special kind of speaker to work in water. Speakers have a hard enough time moving air. The effect of water in the surface of a normal speaker just stops it working. The driver unit has to be able to resist to water pressure obviously this increases with volume and depth plus still be able to generate enough movement to create a sound wave. Specialist speakers are sealed. Google has a few examples.

Ok thanks, right so its harder to create sound in water, but when it is created is there any benefits in the sound and the quality?

It seems to be quite hard to actually find an answer in google.
Cheers.

Ok you can do this really cheap.

Get two platic tubs with lids both the same size. Mount the speaker in one lid and throw the other away. Mount lid in tub and seal with silicon. Put the other tub over the speaker and seal so it's all waterproof obviously routing the cable out. Once it's all dry connect the speaker to a sound system and throw the sealed unit into a pool weighing it down then lay back with your ears under the water. If you clear the air out of your ears you will find the sound is very clear with no echo.

Does it sound good? Yes. Is there a point to it. Not really.

Sound does not travel well in water. I've spent many hours on scuba underwater. At one point a was diving three days a week. Sound travels long distances, I can hear a boat's engine from a few hundred feet away but you can't locate the direction it is coming from.

Some sound travels well some not. If you try to yell through a regulator you can almost be heard two feet away. But if you fill a small pill bottle 1/3rd full of small ball bearings and shake it that sound can be head 20 feet away.

Some 'conceptual' comments:

Sound travels differently through different materials.

The speed of sound is faster in water (because it's more dense).

Human ears have evolved to interact with air.

How can this possibly be related to 'audiophile market'?
