Is SINAD important? - "Myths" about measurements! [Video YT]

Don't knock till you've tried it .

So, are y'all saying a lot of folk have their heads up their a...?

No, I'm saying a lot of reviewers who just like to describe the sound a given device produces with colorful prose are useless.

For example, It took me 15 minutes (wanted good easy to read graphs) to find the following sources to explain a very common issue with non science based reviewers.

TLDR : If the reviewer is none trivially older or younger than you, what they hear will be different.

Age-related Hearing Loss (Presbycusis)

Even if we avoid exposure to very loud noise, the ear's outer hair cells may also simply wear out as we age, leading to age related hearing loss. In this condition, high frequency outer hair cells tend to die off before low-frequency ones, possibly because the high frequency outer hair cells have to work harder if their job is to amplify acoustic vibrations on a cycle by cycle basis. Consequently, patients with age-related hearing loss often have normal sensitivity at low frequencies, but progressively poorer sensitivity for higher frequencies, as shown here:

I was joking, sorry it did not come across that way.
 
Have not watched video as have better things to do but - SINAD is really important. That's why it's being measured. How low one can go is individual. Based on my biased and completely unscientific experience, I would not go below 80dB. Plenty out there that beats that bar with reasonable pricing. So why to explore where the bottom is?
SINAD is controversial as far as audibility at all or during music listening is concerned. It is perhaps a good hearing test for those who listen to their system with no music playing. It is like the "compression" issue with digital music files. It isn't so much "can you hear a difference at all' (I cannot) as "who cares if it can't be heard as the louder music that is playing on top of it masks it from consciousness". A big ado over nothing? Any double-blind ABX tests?
