查询词典 euphonious

After the cut-off frequency has been determined, the active noise-filtered system can be designed with several circuits to filter out those frequencies higher than the cut-off frequency and reserve the speech voice only. Besides, the music signals from the MP3 or a CD player can also be transmitted to the earplug system for increasing the signal noise ratio. The anxiety and tension of patients during treatments can, thus, be relaxed due to the euphonious music and toothaches of the patient might be further reduced.

本研究首先以离线的方式收集各类牙科噪音，然后将它传递到个人电脑，并使用CoolEdit及LabVIEW软体程式，分析出在牙科治疗过程中所产生之噪音的频率范围，最后透过各种比较，找出适当的截止频率，在截止频率(1KHz)被决定之后；针对该截止频率，使用主动式滤波的方式设计出相关的电路，组成主动式噪音率除系统，来滤除那些高於截止频率的噪音信号，只保留语音频率范围；此外透过mp3或cd player所播放出的音乐讯号，也可以同时被传递到耳塞系统来增加信号杂讯比，那麼当病人在治疗时，因为有这音乐可以使病人的焦虑跟紧张获得舒缓。
