For what its worth, despite missing the punchline of the actual measurement, the guy knows what he is talking about. Taking a dB measurement in C weighting over some integration period is how to do it for this scenario. I doubt his meter is calibrated but its doing a good job.

    Taking a dB measurement in C weighting over some integration period

    Yeah, the non filtering of the lower frequencies happens when done correctly, if I recall. I am curious what that actually is, and I am curious what is making those specific frequencies.

    At a certain decibel range of ambient noise, humans become even more sensitive to the lower freqs. Being able to use that knowledge while taking measurements of my own is useful to me.

    I would be interested to know the sound signature of gas turbines.
