Burn in and peer reviewed brain research


Not to broach a religious topic, but I know burn in discussions happen all the time in audio circles. Until today, I had not found any scientific research from the brain side.

This article was interesting:  https://pmc.ncbi.nlm.nih.gov/articles/PMC10898501/

It is a 2024 review in Cureus (Kalchev, PMC10898501) that surveyed the physiological, psychological, and social dimensions of audio burn-in. It found no substantial evidence for mechanical changes producing audible differences, and instead identified several well-documented mechanisms — ear fatigue, confirmation bias, placebo effects, and neural acclimatization — that adequately explain perceived changes without requiring the equipment to have changed at all. 

Has anyone found other literature of this type – physiological, psychoacoustic, rather than engineering/mechanical? I'd be curious to learn about it.

Of course, anyone who wants to put their hand on a bible and swear that burn in is real based on personal experience is welcome to do so, but I'm hoping to find things beyond the anecdotal.

@cleeds we seem to be referencing two different studies.  I have been referring to this one https://www.mdpi.com/2076-3417/15/15/8425

No wonder we weren’t quite seeing eye to eye.

... we seem to be referencing two different studies ...

Ahhh, yes, @jastralfu. You are correct. Mea culpa. The study you've mentioned I haven't yet reviewed. 

I personally believe in burn in. My cables did sound better after about 100 hrs. or so. Tubes, (defiantly) sound better with age. Carts, ect. I know what my system sounds like & when I introduce a new item to my system, I do hear a change. Whether for the good or bad.

Just my $.02 Enjoy the music!  

Interesting comments and thanks for the additional reference. That's what I was hoping for. Glad to see some here have turned to just calling this a study without the quotation marks. It may be a bad study with spurious conclusions, but it is a study.

As for people "personally" attesting to burn-in or calling it "real real," that's special pleading but it's definitely something the OP study acknowledges. The study definitely believes that you believe in burn in. No doubt about that.
