Audio perception A/B tests psychoacoustics
Most of the tests I've seen or seen referenced proceed on the
that the ear is the only part of the body that processes sound.But audio
freqs effect the whole body. The A/B test I mentioned didn't even record
what the subjects heard,it measured the responses of brainwaves. This
suggests ,and I belive that sound effects humans in ways that transcend
their subjective perceptual filters.
I have made careful ,though not scientific( not falsifiable ) observations
of how groove ( entrainment) effects crowds.My exeperience has been that
music that is truly in the groove causes people who aren't listening ,or
interested to be effected as well. In fact ,I don't think it is a groove
it doesn't As Stevie sang" You can tell right away from te letter A when
people start to move"
