It has been well established that unequal air pressure across the tympanic membrane causes an increase in puretone thresholds. Very little information is available, however, concerning concommitant effects on reception and discrimination of speech material. This study was designed to determine whether or not further detrimental effects upon the communication process might occur in the form of decreased speech discrimination ability. The findings established that a high positive pressure in the external meatus can result in a deterioration of the individual's ability to discriminate speech sounds.
鼓膜两侧气压不平衡会导致纯音听阈升高，这一点已经得到充分证实。然而，关于其对语音材料接收和辨别能力的伴随影响，目前所知甚少。本研究旨在确定语音辨别能力下降是否会对交流过程产生进一步的不利影响。研究结果表明，外耳道内的高正压会导致个体辨别语音的能力下降。
