要約(英語): The purpose was also to verify that the precision of this method was at least equivalent to that of a conventional polygraph in a medical facility. I measured an oral throat sound and nose pressure signal at the same time. I measured an oral throat sound when it was with amplitude 100%, 75%, 50%, 25%, 10% of nose pressure signals. I collected breathing and an oral throat sound at the time of the hypopnea and each average of the Peak to Peak level of the amplitude of the nose pressure signal each and I calculated an oral throat sound and a coefficient of correlation of the amplitude of the nose pressure signal and usually demanded correlations.At 100% of the nose pressure signal, the throat sound was 25.96 dB; at 75%, it was 18.11 dB; at 50%, it was 14.47 dB; at 25%, it was 8.54 dB; and at 10%, it was 6.61 dB. A strong correlation between nose pressure and throat sound was shown (r2 = 0.98, P < 0.001).The throat sound and nose pressure signal showed a strong correlation, which suggested a precision similar to that of a polygraph in a medical facility.
