In a series of five experiments, researchers compared small groups of people with or without musical training. They tested participants' accuracy at matching their voices to various pitches, to a target vocal or musical tone, or to other singers.

The study found that anywhere from 40 to 62 percent of non-musicians were poor singers, a rate much higher than shown in previous research.

It also found that roughly 20 percent of people can't sing accurately because they don't have good control of their vocal muscles. Another 35 percent of poor singers have trouble matching the pitch of their own voice to the same sound heard in other timbres, such as when it's coming from a trumpet, piano, or a person of the opposite sex. And 5 percent of lousy singers lack the ability to hear differences in pitch or discriminate between two different sounds.

在一系列五项实验中，研究人员对受过和未受过音乐训练的参与者进行了比较。他们测试了参与者将自己的声音与各种音高、目标声乐或音调、其他歌手进行匹配的准确性。

研究发现，40%到62%没有受过音乐训练的人唱歌不准，这一比例远远高于以往的研究。

研究还发现，大约20%的人唱歌不准是因为他们不能很好地控制声带肌。另外35%的人难以将自己声音的音高与其他音色的声音相匹配，比如小号、钢琴或异性发出的声音。5%的人缺乏听辨音高差异或分辨两种不同声音的能力。
