given the following input from another posting...
"In simple terms a sound that is 57 dB would be in the normal noise floor of any decent sized city. In other words you would not hear it unless pretty close. At 97 dB, you could hear it for many thousands of feet away.
Every 10 dB you double the noise energy of an event so a 97 dB event is 16 times as loud as a 57 dB event. Its been awhile, I might not be saying that exactly right.
... and seeing BRU seems to have a policy of accepting 91 dB, one wonders why BRU surroundings are noisy!

Why don't you find another platform to deliver all your anti-aviation hang ups.....you've more than had your opportunity to lash out at our industry and lots more. In my view this thread has well and truly shot its bolt!!!!!

I dont think that you will be happy until the airport bans all night flights

No worries Mutt. I am going to make those MD-11s quieter. Maybe they won't have to leave then. 
ps. I assume you are talking 747-200s when you say 105 EPNdB(Approach???). I can knock 2 dB off that real easy.

2 dB? Is that all? You better go back to the drawing board and come up with something better Suggest that you look at a sling-shot concept where the aircraft can be silently blasted into the air prior to starting the engines
Get the idea that aircraft noise is your forte, so what do you think about this? Are the manufacturers and airlines living up to their responsibilities as good neighbours?
tgdxb,
I found you the perfect solution.....

747FOCAL,
We dont have a noise problem with BRU as our 747's are totally banned at night.
tgdxb as a resident is seriously concerned about his nighttime sleeping patterns.
As i said before, you appear to have a direct hand in aircraft noise.... do you believe that the industry has lived up to its requirements???
