The waves are sinusoidal in nature, and they have an
amplitude and a
frequency.
声波实质上是正弦曲线，它有振幅和频率。
The amplitude defines how loud the sound is and is usually measured in decibels (dB).
振幅定义了声音的大小，单位dB(杜比)。
The frequency is how many different wave oscillations fit into one second, measured in hertz (Hz).
频率是一秒内有多少不同的波振动周期，单位HZ（赫兹）。
The frequency of a sound defines what its pitch is; lower-pitched sounds resonate less than higher-pitched sounds.
一个声音的频率定义了它的音调，低调比高调振动少。// 是该这么翻译吗？
The A above middle C has a wave that resonates 440 times a second, so it has a frequency of 440 Hz.
中调C之上的A调，其波一秒振动440次，所以其频率为440Hz。
Sound is additive; that is, if two sounds are going through the air together, they both apply their energy to the air molecules around them.
声音是可加成的；就是说，如果两个声音一起在空气中传播，它们都把自身的能量传给周围的空气分子。
When the crests of the sound waves match up, their result is a louder sound, while if opposite crests match up, they cancel each other out.
当声波波峰碰上另一声波的波峰时，其结果是更大的声音(译注：振幅增大了，应该是叠加)；而如果波峰碰上波谷，就抵消掉（译注：振幅一样的话）。
The more things there are creating sound in a room, the more sound there generally is in the room.
啥玩意儿？没看懂。
