    PURPOSE: To investigate the consistency of duration and reproducibility of the pattern of acoustical events related to the swallowing of individuals without complaints. METHODS: Participants were 88 women and 76 men with ages between 6 and 85 years. With a microphone attached to the neck and connected to a computer, each of them performed nine swallowings of saliva, of 5 ml of water, and of 10 ml of water. Based on the acoustic registration of the sounds recorded, the duration of the interval between the peaks of the two main swallowing clicks (T), of the swallowing apnea (dA), and of the relationship between them (T/dA). RESULTS: No differences were found regarding the mean duration between the peaks of the two swallowing clicks (T), the mean duration of the swallowing apnea (dA), and the relationship T/dA in the different age ranges and between genders, except for the T/dA index for the swallowing of 5 ml of water. There was no correlation between age and the measured parameters. CONCLUSION: The swallowing sounds present a characteristic reproducible pattern, which is distinct both from external noises and from other sounds produced in the cervical region. Therefore, they may be used in dysphagia evaluation methods.

    Parâmetros de duração dos sinais acusticos da deglutição de indivíduos sem queixa

    Aim: To investigate the duration of acoustical events related to the swallowing of individuals without complaints, and to determine reference values of related parameters considering the different ages and genders of the subjects. Materials and methods: The sample was constituted by 164 individuals (88 women and 76 men, with ages between 6 and 85 years), without both swallowing complaints and risk or history of dysphagia. With a microphone touching the neck and connected to a computer, each individual performed 9 swallowings of saliva, of 5 ml of water and of 10 ml of water, respectively. Results: The duration of the interval between the peaks of the two main swallowingswallowing clicks (T), the swallowing apnea (dA), and the relation between them (T/dA) were analyzed. The average durations of T were: 201.3 ± 12.8 ms, 179.6 ± 11.9 ms, and 176.5 ± 12.9 ms for the swallowing of saliva, of 5 ml of water and of 10 ml of water, respectively; for dA they were: 1174 ± 128.2 ms, 1436 ± 140.3 ms, and 1531 ± 125.8 ms for the swallowing of saliva, of 5 ml of water and of 10 ml of water, respectively; and for T/dA they were: 0.152 ± 0.012, 0.177 ± 0.018, and 0.158 ± 0.016, for the swallowing of saliva, of 5 ml of water and of 10 ml of water, respectively. Due to the recording order, there was no statistical difference among the results for the different bolus volumes. Also, there was no correlation between age and the measured parameters. However, only for T/dA for the swallowing of 5 ml of water, a significant difference between genders was found: for men this index was greater than for women. Conclusions: There was no difference among different ages or between genders (except for T/dA of the swallowing of 5 ml of water) with regard to the duration between the peaks of the two swallowing clicks (T), to the duration of the swallowing apnea (dA), and to the relationship T/dA.
