A change in body posture from sitting to reclined is known to cause an increase in intracochlear fluid pressure, if the cochlear aqueduct is patent. Previous studies have shown this increase to have an effect on middle ear dynamics. The aim of this study was to investigate whether such increases in cochlear pressure may affect the stiffness of, and hence the resonance frequency of the middle ear. No consistent group or individual differences were shown between the two postural conditions.
如果蜗水管通畅，从坐姿到躺姿的身体姿势变化会导致蜗内液压升高。此前的研究表明，这种升高会对中耳动力学产生影响。本研究的目的是调查这种蜗内压力升高是否会影响中耳的刚度，进而影响中耳的共振频率。两种姿势条件之间未显示出一致的组间或个体差异。
