Some years ago, at a renowned airline, an angry pilot taped the noise in his hotel room, where he was required to rest through daytime. It had been criticised heavily, but deemed safe and adequate by the company. He then took his ghetto blaster and placed it in front of the office of the SVP FO during a meeting and played back the noise. Needless to mention that the managers came blasting out after a few minutes asking what freakin' noise this was, that they could not concentrate for their serious meeting, let alone take a peacful coffee during their short break to recover.
It's all a matter of arrogant perception.
