OSHA probably wouldn't have much to say… The peak he measured would only be outside of their guidelines if the attendants screamed for the entire LAS-SFO flight and then he hopped on a plane and immediately flew back with the same treatment.

Table G-16 - Permissible Noise Exposures

NIOSH says 15 minutes at 100dB, which is still far longer than the combined duration of all announcements on a flight.

I think the 99dB value the author of the article measured is not arbitrary - and was chosen specifically to meet some regulations.

That depends on the flight. I've timed the announcements on some medium-length flights totaling upwards of 30 minutes.

I agree, there are actually very few government agencies that can be bothered to give even half a fart about anything they are essentially charged with. Between Congressional undermining and bureaucratic incompetence, they are essentially toothless.

I see a lawsuit or a public shame campaign as far more effective. How does "United caused my child to have brain damage due to the loud PA system ... oh, and now he's autistic too"? That should work.
