comparison
of
these values is not possible. This difference is
mainly due to procedures used to convert measured sound to
perceived sound. ANSI S3.4, used by both HVI and AMCA,

specifies a procedure for calculating loudness as perceived by a
typical listener under specific conditions. HVI establishes values
