alt Hacker NewsOn a typical day, the atmospheric pressure varies by maybe 150 Pa, or 3 psf. By definition, that’s 137 dB. But it’s imperceptible because the rate of change is so low.

Yeah nah. For all relevant level metering you use a A-weighting curve (weighting the frequencies by human ear sensitivity) so that is not how any of that works.

A sonic boom doesn't exactly average out over the length of the day, though, does it?
Obviously it is assumed we are talking about frequencies in the range of the audio spectrum (which a sonic boom is). Your point has nothing to do with the dB scale.
