A comparison of the speech audiograms of patients with bilateral and unilateral hearing loss due to Menière's disease has shown that when matched in respect of pure-tone hearing levels, speech discrimination at the better ear of the former is appreciably better than that at the impaired ear of the latter. In addition, while roll-over is a characteristic feature of the unilateral group it is conspicuously absent in the bilateral group. More surprisingly, in the bilateral group, despite relatively small differences in the pure-tone hearing levels at the two ears, speech discrimination at the better ear is strikingly superior to that at the poorer ear. It is concluded that patients with bilateral hearing loss selectively make use of the better ear to the neglect of the poorer ear. This could have important implications in the prescription of binaural hearing aids.
对梅尼埃病所致双侧和单侧听力损失患者的言语听力图进行比较后发现，在纯音听力水平匹配的情况下，前者较好耳的言语辨别能力明显优于后者受损耳。此外，虽然重振是单侧组的一个特征性表现，但在双侧组中则明显不存在。更令人惊讶的是，在双侧组中，尽管双耳的纯音听力水平差异相对较小，但较好耳的言语辨别能力明显优于较差耳。得出的结论是，双侧听力损失患者会选择性地利用较好耳而忽视较差耳。这可能对双耳助听器的处方具有重要意义。
