最近欧美教育界中的很多中老年教师无奈反映，上课期间很多学生毫无征兆的情况下偷偷接听电话，极大地影响了课堂纪律......难道如今欧美又推出了什么新款的手机产品吗？是什么原因能够令到上课的学生们在手机无铃声无震动的情况下感知来电呢？一时间众说纷纭，也成为了最近欧美教育界的一大难题！
迷底就在这些顽皮的学生手机铃声上面，因为最近在欧美广为流行了一种据称只能给年轻人听到而成年人则无法察觉的手机铃声——“HighRing”。
只要了解到了声音的原理就应该清楚，人的听力频率范围是20-20000hertz，而成年人和年轻人之间，听力方面也有细微的差别的，在一定频率内的声音，由于成年人在听觉上长久的劳损，很多人在人到中年以后开始丧失对高频率声音的听觉能力，而年轻人在这方面则还有一定的优势，医学上称之为老年性耳聋。大部分年龄在40岁或者50岁以上的成年人具有这种症状。
而在英国，有心人则利用了人体的这一原理，发明了一种特定频率的声效，只针对年轻人士的听觉。
经过了一定的处理，这种年长人士不能听到的声音成为了手机铃声的一种，并且在年轻人群中快速传播开来。“HighRing”成为了欧洲和美国等地区最为热门的手机铃声，在许多禁止手机铃音的场合，比如教室，这种新型铃音可以让成年人无法察觉，也让学校方面非常困惑
參考答案:Recently in the European and American Educational circles' very many middle and old aged teacher reflected reluctantly that, attends class in the period very many student indication situation secretly not to answer the telephone, has affected the classroom discipline enormously ......Has Europe and America promoted what new style handset product now?

Confused the bottom on above these mischievous student handset ting, because it is said that only has been able to hear the handset ting but recently in the European and American widely popular one kind to the young people which the adult is unable to realize - - “HighRing”.
So long as understood the sound principle should be clear, human's hearing frequency range is 20-20000hertz, but between the adult and the young people, the hearing aspect also has the slight difference, in certain frequency sound, because adult in sense of hearing long-time strain, very many people will later start in the human to the middle age to lose to the high-frequency sound sense of hearing ability, but young people in this aspect then will also have certain superiority, in the medicine will call it the senile deafness. The majority of ages have this symptom in 40 years old of or 50 year old of above adults.
But in England, the person with high aspirations has used human body this principle, has invented one kind of spot frequency sound effect, only aims at the young public figure's sense of hearing.
After certain processing, the sound which this kind of old public figure could not hear has become the handset ting one kind, and disseminated fast in the young crowd. “HighRing” has become Europe and US and so on the local most popular handset tings, in many prohibition handset bell sound situation, for instance the classroom, this kind of new bell sound may let the adult be unable to realize, also lets the school aspect be extremely puzzled
