Auditory hallucinations
-Drugs,sleep deprivation,migraines,mental illness can often trigger the illusion of sounds that are not there. We're OK on that front,and have a well appointed acoustically prepped sound area. Now fitted with personal audio equipment approaching 100 K...If there was a mechanic in the can we've tried it.Knowing people in the recording industry did help beat down a few snake oil theories.If it sounds silly...it is, if there's no science that's the red flag. It's an incredible hobby and with due diligence richly rewarding.
