npub1typ5we79rr527q30467hfz8ptfy0h8gxpmfn7j64ak6pk6pv4rfszzc8hh (npub1typ…c8hh) so this is REALLY hard to cover in brief, but “intensity” has a specific meaning, and to be fully accurate, it is not measured in decibels at all.
There’s amplitude power, intensity, intensity level, and sound pressure level, and they all have different dimensions and—importantly—none measure loudness, a psychoacoustic concept. This is like total radiation of a source being in W, but for human vision we use lumens.
In short, “+10dB SPL doubles perceived loudness”
