gnified on applying the ear to B. Even if the wave is onlya small component of the actual wave arriving, the resonator willpick out and magnify this component. Such resonators are madein sets, the pitch of each one being known, and they can then beused to detect the components in a complex note,… … Fig. 661.—Helmholtz resonator. LVI EXERCISES 717 that they are resonators, but not of such a simple type as that ofFig. 661. They magnify certain tones, and these tones are alwayspresent to a certain extent, and when magnified they blend intothe familiar roar of the shell. Exercises on Chapter LVI.…
