1.6MHz的没查到。而且1.6MHz也太高了,清洗用超声波频率绝大多数在30kHz-70kHz内,频率再高,效率下降。这和汽车大灯一样,6500K的色温都有些发蓝了,不是越高越好。
给一个它的使用手册英文版(pdf)链接地址: http://www.esalton.com/static/manuals/SB200U.pdf
我把其中关于双频的部分复制到这里供参考:
Q: How does the Dual Frequency Ultrasonic Toothbrush work?
A: The Dual Frequency Ultrasonic Toothbrush uses advanced dual frequency technology to provide its dynamic cleaning power. It is the worlds first to feature deep penetrating 1.6 MHz ultrasonic waves coupled with 18,000 SPM carrier waves.
With just regular brushing, it’s unique foaming and scrubbing action effectively removes nearly all plaque to help you maintain a professional clean feeling everyday. The brush reaches well below the gumline to disrupt the bacterial process. This results in a significant reduction of gingivitis and bleeding while promoting healthier gums.
这里有一个视频英文讲解(繁体中文字幕)的链接:

我因为牙齿不好,所以想买一个好点的牙刷,但是现在在超声波牙刷与声波牙刷之间拿捏不定,希望能听到更多专家的意见。谢谢!
