• Calibration ensures that output levels correspond to THX refer-
ence levels (75dB) for input sources such as DVDs.
• Eliminate extraneous noises in the listening space such as con-
versations, air conditioners, and sounds that filter in through
open doors and windows.
• Remove objects (including people) that obstruct the line-of-
sight path between the SPL meter and the speaker being mea-
sured.

meter reading from the primary listening position.
