The waves are sinusoidal in nature, and they have an
amplitude and a
frequency.
聲波實(shí)質(zhì)上是正弦曲線，它有振幅和頻率。
The amplitude defines how loud the sound is and is usually measured in decibels (dB).
振幅定義了聲音的大小，單位dB(杜比)。
The frequency is how many different wave oscillations fit into one second, measured in hertz (Hz).
頻率是一秒內(nèi)有多少不同的波振動(dòng)周期，單位HZ（赫茲）。
The frequency of a sound defines what its pitch is; lower-pitched sounds resonate less than higher-pitched sounds.
一個(gè)聲音的頻率定義了它的音調(diào)，低調(diào)比高調(diào)振動(dòng)少。// 是該這么翻譯嗎？
The A above middle C has a wave that resonates 440 times a second, so it has a frequency of 440 Hz.
中調(diào)C之上的A調(diào)，其波一秒振動(dòng)440次，所以其頻率為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.
聲音是可加成的；就是說，如果兩個(gè)聲音一起在空氣中傳播，它們都把自身的能量傳給周圍的空氣分子。
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.
當(dāng)聲波波峰碰上另一聲波的波峰時(shí)，其結(jié)果是更大的聲音(譯注：振幅增大了，應(yīng)該是疊加)；而如果波峰碰上波谷，就抵消掉（譯注：振幅一樣的話）。
The more things there are creating sound in a room, the more sound there generally is in the room.
啥玩意兒？沒看懂。
