  • 答案:B

    根据听MP3之后的听力测试,对照组和收听组之间没有发现太多的差别。根据是第四段第一句:Hearing tests were carried out before and after the exposure, which found significant threshold or emission shifts were observed between almost every session of the noise exposure group compared with the control group.在听音乐前后分别进行了听力测试,结果发现几乎每次都能够在噪音接触组和对照组之间观察到重要的临界点和发出声音的变化。因此该句话是错误的。
