Why A Boy's Voice Changes
为什么男孩会变声
For adolescent boys, a changing voice that cracks in the middle of a sentence can be a great embarrassment. Though embarrassing, a cracking voice is a natural part of adolescent development. As a boy goes through adolescence, his secondary sex characteristics develop. One of these characteristics is the rapid growth of the larynx and vocal cords.
对于青春期的男孩来说,一句话说到一半突然变声确实令人尴尬(brEH_V1nS5d49qG。虽然如此,但这是青春期发育的一个自然的过程lNWZXUz.ieJ@AMYf。当男孩进入青春期,就会出现第二性征fv=77,Y;C-TJE@Xw。其中一个特点就是喉结快速增长,声带发生变化bmy([xOFd08p[6

A boy's voice deepens as his larynx develops because the bigger the vocal cords, the deeper the voice. In fact, vocal cords are similar to other musical instruments in this regard. The longer the harp string, for instance, the lower the note it plays. Similarly, if you are blowing into a bottle to create a certain pitch, the larger the bottle, the lower the pitch. When it comes to voices, the bigger the vocal cords, the lower they resonate, and the deeper the voice will be.
随着喉咙的发育,男孩的声音变得低沉,因为声带越粗,声音越低沉L(7QMP,QO;2kZa。就这一点而言,声带其实类似于其它乐器ly)Dm,f0AB2w_FO。例如,竖琴的琴弦越长,演奏出来的音符就越低沉S],3JO6*vS6。同理,如果向瓶子吹气来创造音乐的话,瓶身越大,音高就越低W[I7kXSsLAAa.B8+iAtw。就说话而言,声带越大,共振的频率就越小,于是声音就越低沉6eUyJrE4nxn6R]e(6TQm
But why does a boy's changing voice break and crack? For the same reason growing adolescents are often gangly and awkward: the brain is becoming accustomed to working with bigger body parts. Even for an adult, a consistent and even voice depends on the brain's ability to constantly monitor the sounds that come from the voice.
但为什么男孩会突然变声?成长中的青少年往往瘦削又笨拙,道理也一样:大脑还不习惯身体的某个部位变大QUUB!@2AC1YKrVH*u。即使对于成年人来说,一致平稳的声音也取决于大脑对声音的监测和调控能力是否一致PWKuc]1N~SD+|
The brain can do this quite easily under normal circumstances. But, when a boy's vocal cords enlarge, the brain must relearn how to monitor and control the voice. A cracking voice is proof that an adolescent boy's brain hasn't become completely proficient at coordinating its careful monitoring of the sounds coming from the vocal cords.
在普通环境下大脑能非常容易地做到这一点Tub=((=^eC。但当一个男孩的声带变大,大脑必须重新学着监控声音vXG#|41pVJHyAJE#l5G。突然变声就是青少年的大脑处理声音不协调的表现,这时大脑还不能很好地协调声带传出的声音gt27-I#m|SLj32t^u9J
