Extract

Those who were present at the reading of Mr. Spottiswoode's paper, “On Beats and Combination Tones,” last session, may remember an observation made in the course of the discussion to the effect that the excellence of the apparatus employed goes for a great deal in acoustical investigations. I have to bring before you to-day an attempt to obtain efficient apparatus, somewhat less costly in its construction than that exhibited to you by Mr. Spottiswoode.

But later it was fully realised by several that even small movements of the head of the listener produced considerable differences in the sound heard.Google Scholar
