The Placebo Effect


One of the things that should be taken into account in the evaluation of audio equipment, tweaks, etc is the Placebo Effect.

In the medical world, Placebos (open label or concealed) appear to mostly work on subjective symptoms, such as pain. They don’t work on an objective symptom — something a doctor could see or diagnose, such as a fracture on a bone. Placebos don’t shrink tumors, they don’t change your diabetes, and they’re not going to actually lower your blood pressure for more than 15 minutes, Basically, placebos appear to work on things that pass through the brain’s perceptual systems — where they can prompt the release of opioids and other endorphins (chemicals that reduce pain) in the brain. Bottom line, placebos can result in perceived improvement even where no actual improvement exists.

The same applies to our hobby. Probably too often, we sense improvement in SQ because of the Placebo Effect. Our money spent, hardware bias's, effective marketing, or being influenced by the experience of others (regardless if true), often have us believe that we have obtained improvements that don't really exist. This is not necessarily a bad thing because a perceived improvement, whether real or imagined is still an improvement to the listener. This may explain part of why certain "improvements" can't be measured.

sugarbooger (and I thought MY moniker was odd 😊), if you were read my post carefully you’d note that I wrote nothing about the quality of tuners, or the improvements that have been made in recent years; I assure you that I know all about it. While my instrument is not piano, I have been in the presence of professional piano tuners while they do their thing literally hundreds of times over the years and I have spoken to a several. Not one relies entirely on the tuner without making final adjustments by ear in order for the instrument to sound correct. That was my point and only point. Again, as I wrote previously and as always, when it comes to musical matters the trained human ear is more sensitive than any electronic device.
“Assist” is the operative word. The electronic tuner is used primarily as a reference; usually in order tune middle C and then the middle octave. This becomes your reference. After that the technician’s ears come into play. If one relies entirely on what the electronic tuner tells you, the result will be a piano that sounds out of tune. Octaves in particular are impossible to make sound right with an electronic tuner and adjustments must be made by ear. Humans tend to hear low pitches higher than they actually are and high pitches lower than they actually are in reflexive attempt by the brain and to try and bring what we hear within the range of the human voice; so, fine adjustments must be made by ear. No electronic device can do what the trained human ear can do.
Seems to me that we are confusing two separate things. As described above by mahler123, as concerns audio, if the perceived change is real it is obviously not due to Placebo Effect. Whether the change is an improvement or not is a subjective call and is a separate issue.

On a more mundane level, it seems to me that some listeners are simply reluctant to accept the simple fact that some are simply blessed with hearing that is more acute than that of others; or, have developed their hearing acuity by way of training or experience more so than others.
