Merging frequency and upper hearing threshold

 Product No: P0819000
The limits of hearing are to be determined using a sine-wave generator and some headphones. The upper limit of audible frequencies varies between 20 and 5 kHz and depends upon the age of the listener. Once the frequency is below a certain lower limit, individual sounds merge into a continuous low frequency tone. This merging frequency usually lies between 16 and 20 Hz but does not vary with age.
