audibility助记

? sults show that the hearing loss in group 1 caused by low frequency noise was slight and the audibility of the ani-mals recovered in 24~ 48h after exposure, whereas the hearing loss caused by narrow band noise was more marked-ly than the above;

结果表明，第1组动物由低频噪声引起的听力损失轻，暴露后24～48h听力恢复正常，窄带噪声引起的听力损失较前者重；

Results All cases were operated successfully. 78 cases ( 132 ears) were followed up with 7~ 12 months. These cases hearing were improved significantly, pure tone threshold average was 21.6 dB and audibility threshold elevated 28 dB averagely.

结果所有置管均一次完成，术后7～12个月复查78例（132耳），疗效显著，纯音测听平均为21.6dB，听阈平均提高28dB。

Touch is one of the most important ways for mankind to know about the environment, virtual reality will be depressed in immersion and imagination without touch feedback, and a VR merely including video and audibility is far from a perfect one.

触觉是人类对事物获得认知的重要途径之一，虚拟现实系统如果缺少了触觉就会大大降低其沉浸感和想象力，只具备视觉和听觉的虚拟现实系统是不完整的。
