Remember that in audio, the FTC sets some standards, but doesn’t measure the gear. It’s up to the equipment makers to measure and make claims, and occasionally magazines test them to see how close they are to the specifications.
>>>>>Really? The FTC sets standards for home audio? Id be curious to see any more info. as i already stated, manufacturers are under no obligation to either measure anything or make any claims. They can if they wish. there are some things in this hobby that are simply not amenable to measurement. See if you can name 3.
We are far from any of that I’m afraid. It’s up to academia and manufacturers and even interested hobbyists to explore and then define measurement protocols since there is a complete lack of them in audio. If someday that happens, then maybe down the line we’ll have legal standards for labels on racks like food nutrition content.
>>>There are no measurement requirements or protocols for home audio. Obviously there are certain standards involved such as Redbook CD and DVD and Blu Ray. There are no standards for noise, distortion or even Dynamic Range of home systems. Standards and protocols are not legally binding AFAIK\, CDs are produced that are not Redbook for example. Where are you coming up with this stuff?
Have a nice day
