When a bass control is adjusted for maximum bass emphasis, the level of sound from the speaker may be appreciably higher at frequencies below 100 cps than it is at 200 cps. But there may be very little energy in the first partial (fundamental) of all low notes produced by a prominent bass instrument of an orchestra except for one or two notes in which there is considerable energy in the first partial. Consequently, when appreciably more emphasis is applied to first partials than to higher partials, the sound of the fundamental frequency of these one or two notes is greatly emphasized and the sound of all other notes produced by the instrument is little affected. It is explained why the large differences in the energy which is in the fundamental frequency are not noticeable when one is listening to the music when it is played, and it is concluded that the characteristics of a bass emphasis control when it is adjusted for maximum emphasis should be such that more slope is provided between 800 and 200 cps than is customary and so that very little slope is provided between 150 and 50 cps.
