Any sound waves that happen to be propagating through the water will bounce
off of any objects that are there. No device is required to make that happen.
A system that intentionally generates sound waves underwater, and then receives
and analyzes those that return after bouncing off of something in the water, is a
SONAR system.
Sonar. It is an acronym for Sound Navigation and Ranging.
S.O.und N.avigation A.nd R.eflection, or SONAR
the system is called sonar

I don't know this for a fact but is what I think happens is when you talk the sound wave's of you voice bounce off the cave, because it's so open and empty, and there's nothing for it to run into like chairs tables cars doors stuff like that,it's empty and hallow. That's what i think. go to Google or WikiPedia to find out for sure. :) Have a blessed Day!
Glass objects break when the vibrational frequency of the sound causes the atoms in the glass to vibrate more frequently until they are out of control. If the frequency doesn't match the natural vibrational frequency of the movement of the atoms, the atoms don't get any additional energy from the sound. Think of it like a trampoline. If one person jumps at the right time, they can send their partner much higher (and often out of control). If you jump at a different time, you can actually take away their energy ("bounce").
It makes a dull sound, while a metal makes a ringing noise like a gong!
a loud speaker and for no sound it is a loud speaker with a cross on it
Sound velocity in steel - 5960 m/s Sound velocity in Stainless steel - 5760 m/s

Sonar
sonar is a device used underwater for locating submerged objects and for submarine communication by means of sound waves.
The use sound to detect what is around them. The echolocation sound bounces off objects and then back to the bat.
SONAR stands for SOund Navigation And Ranging.SONAR is a device that uses ultrasonic waves to measure the distance , direction and speed of underwater objects.
they probably would use a sonar which is a device that bounces sound waves off under water objects and then records the echoes of these sound waves. =]
Sound travels through water. Sound reflects from objects with different densities. You can listen for the echoes.
Sonar SOund Navigation And Ranging
sonar - by bouncing sound signals off the bottom of the ocean, they were able to map the depth of the ocean. Deep sea diving would take too long. Satellites were not in orbit until the 1970's and submarines were not necessary since sonar could be done from the surface on a boat.
dolphins send out a click that bounces off of other objects near them. The longer the time to get the vibrations back to the dolphin is how far away the object is in front of them.
it is used my SONAR. When something is underwater. I.E fish. The sound sends a frrequency to the fish, and it bounces back off the fish back to the SONAR. and thats how people know where to go and how to find stuff underwater
