Author Topic: Equalization using a SPL Meter And a Audio CD Joe Grace Film Handler Posts: 44 From: Maine Registered: Feb 2000 posted 09-13-2000 06:39 PM                     Would it be posible to Equalize a theater using a Sound Level meter and a Test CD that plays tones starting from 20hz to 20khz? I know that this might not be the corect way, but has this been done before? How well does it work? It works good on a home stereo, but that is a little different. Is this not a good idea?

Get a hold of an RTA, mikes, and a pink noise generator (*NOT* a pink noise CD or pink noise film loop) and properly equalize the system. Unless you have 'calibrated' ears, its never going to sound right...

First, do no harm.
