Hydrophone
a musical instrument used in Panay consisting of a tube with a pipe. It is played by placing water in the tube and blowing the pipe. The presence of water produces a whistling sound.
A rain stick can give that effect. It's a percussion instrument.
He was swimming having taken a break from recording. He probably got his feet tangled in the weeds in the water which dragged him under.
Made from leaves of nipa or coconut sound is produced by blowing air on the deed.
My idea is that the water vibrates and sends sound waves through out the water and up the bottle creating the echo. I think that the more water the more high pitched the sound because since in water there are less particles to interfere with sound waves and water muffles sound. So in the bottles with less water the sound is deeper and lower pitched because the sound waves are mostly reverberating against the bottle.
Sonar detector.
Sound does travel under water otherwise the Humpback would be wasting its time singing!
When under power the sound of the engine and water lapping at the hull. When under sail the sound of water lapping at the hull.
Periscope
sound is not louder in water because of the water that is in your ears and the sound would be very faint.
Sound is simply the vibration of matter so it exists under water, in rocks, and even in lava.
The sound wave creates light when it impacts a bubble under water because of the acoustics.
Sound travels by creating vibrations in the air. (Or in the water if the source and/or the reciever are under water.) These vibrations in the air are sound.
Yes sound can go through water because when you say hi under water you are producing air buble that make sound.
yes, of course.
maybe
A hydrophone is an instrument for listening under water. There also seems to exist some kind of musical instrument called hydraphone.
