    Objectives: To describe the acoustic parameters of the sound of the swallow of individuals without complaint and to relate to the acoustic parameters of the swallow (peak of frequency, peak of intensity and duration) with sex, volume and consistency of food. Material and Method: The sample was composed by 118 individuals (58 men and 60 women) with ages between 18 and 39 years (27,29 means age), without complaints with regard to the swallow and absence of former or current history of mechanic or neurological dysphagia, illnesses, traumas and/or surgeries in head and neck area and/or anatomical alterations of the verbal socket that could influence in the functions of speaking and swallowing, besides alteration of skin in the cervical region. It was used a cardiologic auscultation microphone adapted for capitation of the sounds of the swallow, located in the cervical region hardwired to the micron computer. Three swallows of saliva, liquid (water) and paste had been recorded (yoghurt), being the two last ones in the volumes of 1, 3, 5 and 10ml, in the total of 27 swallows for individual. The sounds recorded were analyzed by the software acoustics Audition analysis Adobe version 15.0. Results: The average values of the peak of frequency, peak of intensity and duration of the sound of the swallow in the men were respectively: 509,8191(Hz), -10,1211(dB) and 0,3976(s); the average values of the peak of frequency, peak of intensity and duration of the sound of the swallow in the women were respectively: 468,4373,4373(Hz), -14,0142(dB) and 0,4150(s). There was a significant statistics difference in the parameters peak of intensity of the sound of the swallow that was bigger in the men than in the women; when compared to the consistence, the duration of the sound of the swallow of the liquid was greater that in the paste for the volumes of 3, 5 and 10ml. Sound of the swallow with the tested volumes did not have statistics difference in the correlation of duration. Conclusions: There as not difference between the peaks of frequency and duration of the sound of the swallows of men and women. There was an increase in the peak of intensity of the men compared to the women. Considering the total of the sample, the duration of the sound of the swallow of the liquid was greater that the paste for the volumes of 3, 5 and 10ml. Correlation was not established between the duration of the sound of the swallow and volumes. There was an increase in duration of the sound of swallow with increasing volumes to liquid consistency, except with 10ml.
