THE ACOUSTICS
OF THE

LISTENING ROOM
——
~
The ideal listening room is one where the transmission fre-
quency response is fiat. In actual fact, however, the
acoustics vary depending on the effects of the structure of
the room and its furniture, and on the listening position.

Frequency ——*—
Although there is minimal treble attenua-
tion in a listening room surrounded by
hard walls and windows and having a
bare floor, the bass sounds are reflected
to @ great extent.
In rooms like these, turn up the 150 Hz
control slightly.
In a room surrounded by drapes and with
carpets on the floor, there is minimal
reflection of the sound and both the bass
and the treble are absorbed.
In rooms like these, turn up the 60 Hz con-
trol slightly and turn up the frequency
controls above 2.4 kHz gradually.
The above examples are extremely
general. —
The acoustics undergo change in accord-
ance with the furniture in the listening
room, the height of the ceiling and the
listening position, among other factors.
Play the music and try operating each of
the controls to produce the best effect.
