ACOUSTICS

- A. EFFECTS OF FURNITURE

The quality of reproduction from any. loud-speaker depends, to a considerable extent, on the room in which it is used and also on its place in the room and even the furnishings of the room. A similar effect is obtained with a piano in a room. When the furnishings and hangings are all removed and the piano is again played the result is quite different and the difference is emphasised as the loudness of the playing is ■ increased. The jumbled result of the music, in the empty room was not present in the furnished room, because of the absorption of the sound waves by the furniture, causing the sounds* to die out quickly and not be prolonged so as to interfere with laiei: sounds. This absorption is- knoAvn as damping, and on the degree of damping in a room depends the clarity of the reception, in this respect it is obvious that tho same speaker Avill behave quite differently in different rooms, so. in choosing a speaker, try it where it is to ho used most, and try different types until the one most suited to the acoustic properties of the room is obtained.
