A comparison between swallowing sounds and vibrations in patients with dysphagia

Cervical auscultation (CA), the observation of swallowing sounds or vibrations during deglutition, has been used in the screening of swallowing disorders [1 –10]. The acoustic information observed during swallowing has not yet been clearly delineated to represent specific physiologic events occurring during swallowing because the signals are so complex, and numerous events are taking place simultaneously during a single swallow. In CA, a stethoscope o r an electronic acoustic/vibratory detector, such as a microphone or an accelerometer, is placed on the patient’s anterior neck on the skin in the region of the larynx to listen to or record the swallowing acoustics or vibration signals [1–3,5,7,8,11,12].
