Audible acoustic polarity effects require the ear’s asymmetric detection process

Evidence

So, as speculated at the outset, the asymmetrical detection process in the ear can yield audible polarity effects if the signal and the listening conditions are right. The problem is that there appear to be no audio or film industry standards that ensure the delivery of such absolute polarity sounds from the microphones, through the extensive electronic manipulations in control rooms or dubbing stages, which may be different for different components of a mix, and finally through the playback electronics and loudspeakers at home. — Toole, Floyd E, Sound reproduction- the acoustics and…, 983

• QUESTION: Why no industry polarity standard exists, given it is demonstrably audible in select program material, seems worth chasing.
