You don't specify what occurrences you are asking about.
All passenger jets today travel at less than the speed of sound, and most military jets also fly at less than the speed of sound.
There have been passenger jets run by Russia and by Concorde that traveled at greater than the speed of sound, but none are currently operating.
Whenever any jet or vehicle breaks the sound barrier a sonic boom is generated. I believe there is some military technology to reduce the boom, but it does still occur.
When a sound wave bends around a barrier so you can still hear the sound even though you can't see the source, it has undergone diffraction. This phenomenon occurs when the wave encounters an obstacle or aperture that causes it to change direction and spread out.
A broken string must be replaced or repaired or your instrument may not sound correct.
faster than the rate of which sound passes. passing through a sound barrier and even still faster. in the gradual moment of passing through the set rate a sonic boom is created.
yes
The opposite of being still could be moving, or restless, wiggly, jumpy.The opposite of still occurring (at this time) would be "no longer" occurring.
It really depends what mic you have. In this case if you have a ear set, (Sony, play station 3) brand, then you can still hear people in the headset and talk to them, but you can't here game play sound because that comes out of the TV. If you have a headset such as turtle beach and Astro's etc, you can still hear people and you can talk to them while listening to game play sound in the headset. If you're aiming for a mic, I would recommend buying a headset, because your sound is broken in the TV.
He just has a young voice and his voice hasn't broken yet. He's very very late, but hey, I think he'll sound worse once it breaks!

The Bell X-1 rocket plane first exceeded the speed of sound on 19 January 1946. The piolet reported big problems with serious shaking of the aircraft that we now understand to be as a result of the sonic boom
The phrase "is still not fixed" is grammatically correct, but it may sound awkward depending on the context. It implies that something remains unresolved or broken. For clarity, you might consider rephrasing it as "it is still not fixed" or using a more specific subject to enhance understanding.
Mr. Chuck Yeager is still very much alive.
yes a bunny will live with a broken paw
