If I posted 5 links / videos, and at least 2 of them are totally false/wrong, and the rest are at best highly questionable, then I would not be making disparaging remarks about others that have nothing to do what is being discussed.
Not in acoustics, concert halls, theaters, and recoding studios have been very consistent with standards. See THIS LINK.
The ASA standards are mainly around fundamental technology aspects of sound, as evidenced by the types of standards the publish: https://asastandards.org/working-groups-portal/ The ANSI/CTA link I published for Consumer Speakers is more relevant for this discussion. The ANSI/CTA-2034 standard is 50 pages long, but still does not go into really deep detail on underlying measurement practices, but it is fair assumption the equipment is following ASA standards where applicable.
