“…Concerning the record of signs and symptoms, throat clearing was self-reported in a higher percentage, which is consistent with findings of a research that consisted of 272 teachers (22) in the municipal network of São Paulo (82.4% of the case group, 64.8% of the control group, p=0.011). In general, this symptom is present among subjects who make excessive use of voice, who may have laryngopharyngeal reflux associated or not with the use of voice (15) .…”

“…At the same time, were evaluated the MPT. The volunteers remained in orthostatic position with the Behringer ECM 8000 microphone (frequency response from 15 kHz to 20 kHz) join it to professional digital recorder (Zoom H4n; 96 kHz, 16 bits, with 50% of the recorder signal level), Fixed in a pedestal and positioned in front and at 90° angle of the mouth (23) , keeping the distance of 4 cm between the microphone and the mouth, to capture the emissions of the vowel (24,25,26) . They were instructed to, after a maximum inspiration, sustain during an entire expiration, with a normal pitch and loudness, the vowel /a/, which was recorder and measured by seconds.…”
