Reection-free zone around the
listening area
First order reections can have high level while subsequent reections become
smaller. Control room design minimizes the rst order reection level reaching
the listening area. Reections arriving very soon after the direct sound from the
monitor are called early reections. One aim of control room design is to reduce
or eliminate early reections, having mainly the direct sound from the monitors
reaching the listening area.
