Try going to the options and turning the sound effects on and off, then tap a few things to make a sound. Do this several times and the sound might turn back on. If not, just turn the device off and on (press and hold not simple tap) afterwards the sound will definitely come back on.
To find shoals of fish by bouncing sound waves off them. And;To check the state of the bottom if trawling, and also to avoid going aground- by bouncing sound waves off the sea bottom.
If you have a very powerful pellet gun and use very light pellets, getting a speed of over ~1150 feet per second is possible and will break the sound barrier. If you use WD-40 on the gun, it is recommended to wipe it off and then use gun oil. If you leave WD-40 inside the gun it could make the bullet faster, but it's more dangerous and wears down the parts inside.
Light travels faster than the sound. Light from the sun reflects off the smoke to your eyes at a rate of 300 000 000 m/s, while the sound from the gun (happening at the exact same time as the reflection of light off the smoke) travels at only 340 m/s. Therefore, the light will reach your eyes before the sound reaches your ears.
is when sound going up wave is going down
There were firing of bullets and shells going off so it would be very noisy and scary.
Weapons do not just start going off.
Depending on the gun, if its huge then the sound and shock waves from the gun will shift the snow and cause an avalanche. Sometimes even a simple scream is enough to set it off.

Because light moves substantially faster than sound.
Yes, it is called "spiking", although it is likely to cause the barrel to explode if the gun (or artillery piece) is fired. YOU CANNOT PREVENT A GUN GOING OFF, BY INSERTING YOUR FINGER INTO THE BARREL
The A in wagon has a short A sound, the O has a schwa sound (wag-un).
check the wires.
A normal conversation is about 70 decibels (dB). A gun firing off is about 140 dB.

Sonar is sound waves bounced off a object so if you are going the speed of sound the waves cannot bounce off the object and determine the speed of the object
