Many investigators have worked on the problem of determining the minimum amount of sound energy necessary for audible perception, but most of the investigations have been concerned with sounds of ordinary frequency and very little attempt has been made to make such a determination in absolute units near the upper limit of the range of audition. The mechanical difficulty of securing tones of sufficient intensity at these high frequencies is great, and, furthermore, it is not so easy to ascertain the amount of sound energy given out from the sounding apparatus at these values of frequency as at lower values.
