Observation measures were bone conduction thresholds, changes of ossicular chain, preoperative and postoperative changes of pure-tone hearing.
观察术前骨气导阈值，听骨链改变，手术前后纯音听力改变。
But if you say it in an excited tone with a happy face, it's a friendly way of saying you can't believe what you're hearing.
但是你以一种很兴奋的语气，一脸幸福友好的语气，意思是你无法相信自己所听到的。
Human auditory perceive not only includes the level, tone and timbre of sound, but also the sound location, which is called the spatial hearing ability.
在人的听觉感受中，除了声强、音调和音色外，还包括对声音空间特性的感觉，这就是人耳的空间听觉能力。
Pure tone audiometry: Slight sensorineural hearing loss mainly at the lower frequency may be detected during or soon after attack. It may be recovered or lightened after the attack.
纯音测听：发作时或发作后不久，可检测到轻度的、以低频听力损失为主的感觉神经性耳聋，发作后恢复正常或减轻。
This too causes the waveform to lose energy as well as, in turn, frequency and pitch, resulting in you hearing a distorted, lower tone than what people hear directly from out of your mouth.
这同样使声波能量降低，随之带来音调和音高的降低，使得我们自己听到的声音远低于周围人直接听到的声音。
Methods 50 patients received standard pure - tone and extended high frequency audiometry for hearing measurement.
方法对50例压力性鼓膜穿孔患者的常频和扩展高频测听的听阈结果进行分析。
Methods: 11 subjects abilities to detect near threshold pure tone levels were measured in different noise free from hearing disorder.
方法：测试在不同的噪声水平时听力正常的11名受试者感知听阈附近纯音的能力。
