Abstract
Frequency response characteristics of six popular stethoscopes are reported for the higher frequency range (to 3000 Hz) to supplement equivalent measurements for the lower frequencies (35–1000 Hz) published previously. Spectra of the sounds of swallowing from the throat, transduced with an accelerometer, demonstrate important frequency composition in this higher range. Two stethoscope models were found to have superior transmission characteristics for use in cervical auscultation of swallowing sounds.
