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.

... This study can, at the very least, conclude that any perceived changes due to burn-in is not a result of  physical changes to transducers from burn-in.

That’s not at all what the study actually concluded, is it?

Concluding thoughts

The phenomenon of audio burn-in sits at a fascinating crossroads of empirical science and personal experience. While debates continue within the audiophile community, it is evident that our perceptions are shaped not just by equipment mechanics but also by our unique auditory physiology and sociocultural influences. By appreciating these complexities, we can foster a more comprehensive understanding of sound perception and its implications.

Of course, the reader is free to form his own conclusions from the study. It appears that some have become so emotionally attached to it that they have done just that. And that’s fine. But it’s not the conclusion of the study itself, and I don’t think you’ll find any evidence in the study that suggests otherwise.

 

@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!
