To determine and analyze both groups ′ temporary threshold shift ( TTS ) following high level noise exposure. 测量两组高强度噪声暴露后的暂时性阈移(TTS)。
Temporary threshold shift ( TTS ) was tested as the index. 以暂时性听阈位移(TTS)作为观察指标。
Objective To investigate the effect of noise and Propranolol on temporary threshold shift ( TTS ) of the cochlear compound action potential ( CAP ) and cochlear blood flow ( CBF ) in chinchilla. 目的研究噪声和β受体阻滞剂普萘洛尔(心得安)对灰鼠耳蜗复合动作电位和耳蜗血流的影响。
Conclusion Sound conditioning could reduce temporary threshold shift by high level noise and has some protect effect on the auditory system against traumatic noise. 结论噪声习服性暴露可降低高噪声引起的TTS,并对听觉系统有一定保护作用。
Two years later, temporary threshold shift ( TTS ) was measured. In the meantime the symptoms of vegetative nerve functional disturbance were inquired. 两年后,检测每个受试者暂时性听阈位移(TTS),并调查其植物神经功能紊乱症状。
