Mach 1 Sound

[Xfactor]

As everyone has probably noticed on BMS and Falcon when you break mach 1 the cockpit goes quiet. Is this realistic when breaking the sound barrier? Everything I've heard in other places breaking mach1 you really don't even know other then looking at the mach gauge?

Any insight?

well, think about this for a second. You r traveling at Mach1...the speed of sound. Meaning that you are traveling as fast or faster than your own sound. With this being the case....it would seem that u wouldn't hear your own sound anymore...or hear your own sonic boom because u would be so far in front of it by the time it occured. So basically...to the best of my knowledge, not hearing your own sound anymore is correct. Other than this...the only way to know if u have reached/exceeded mach1, is to look at the airspeed indicator.

The only sound you won't hear anymore, if you are able to hear it at all, is the engine sound. So yep, you can only see it by looking at your Mach meter.

Unless you BLOW your canopy.

Then you can hear a shiit-load of noise.




Try this at home when you're bored, and you have no neighbours' gardens to urinate in.

There is no change in sound when you hit Mach 1. The only way you know that you have done it, is your airspeed indicator/Mach indicator. In the T-38 if you watched really closely you could see the needles jump a little as a result of the air disturbance around the plane as you pushed through the barrier.
In the Viper the cockpit doesnt get quite, or engine noise get quite, etc. It all sounds the same:bigsmile:
CHEERS

Does this imply that engine sounds are barely audible at all regardless of sonic condition? Would Falcon's supersonic engine sounds be more accurate for subsonic flight, the current subsonic sounds being too loud? hm...

For the new sim we will be making it more realistic. The F-16 is really quite inside with your helmet on. The sounds do not vary much with speed. At extremely high speeds you get a few odd noises here and there, but no extreme variances.

Hate to bring a dead topic back to life, but wanted to throw my $0.02 in.

AFAIK; the sound in the pit doesn't change because the noise you hear in there is mostly caused by reverberations throughout the aircraft. True?

[Sundowner]

Yes, the sound is a wave as you all know - and to put it simple: that wave have to travel in a medium (for instance air) - the more dense that medium is the "sound speed barrier" is bigger - so when that wave is traveling in body of aircraft which is made of aluminum, this sound speed is many times bigger than in air surrounding it. That's first thing - second: a medium that you are in is standing still comparing to your years position, so inside that plane you will always hear everything.... well untill you go deaf :wink2:

I would imagine that since you can hardly hear the engine in the cockpit, especially in the 16's anyway, that nothing would change. You would still be able to hear, oh hell, i dont know what you call it - i know in a car its called roadnoise, only in a plane it is coming from the air! You guys know what i mean!
