function, the r eve r be r ations a r e measu r ed with the standing waves cont r olled, so the r eve r b cha r acte r istics g r a p h shows the cha r acte r istics
with the effect of the standing waves eliminated. By cont r ast, the
Reverb Measurement
function measu r es the r eve r be r ations without
cont r olling the standing waves, so the g r a p h indicates the r eve r b cha r acte r istics including the effect of the standing waves. If you wish to
check the r eve r b cha r acte r istics of the r oom itself (with the standing waves as such), we r ecommend using the Reverb Measurement
function.
