耳塞式耳机与尺寸更大、更笨重的耳套式耳机相比对听力造成的损害大。许多数码随身听配置的耳塞式耳机被直接塞进耳朵里,能够将声音信号提高9分贝,可是,人们并没有意识到他们为了掩盖背景噪声而将音量调高,这可能会对听力造成一定的损害。所以,人们应当将数码随身听的音量设置为不超过最大音量的60％,每天连续使用耳塞式耳机的时间不超过30分钟。对于希望延长音乐收听时间的用户来说,应该选择能够消除噪音的特殊耳机。
Earphones are more damaging to hearing than earphones that are larger and heavier. Many earphones equipped with a digital walkie-talkie are plugged directly into the ear, which can increase the sound signal by 9 dB. However, people do not realize that they increase the volume in order to cover up background noise. This may cause some hearing loss. damage. Therefore, people should set the volume of the digital Walkman to no more than 60% of the maximum volume, and use earbuds for no more than 30 minutes a day. For users who want to extend the music listening time, special headphones that can eliminate noise should be selected.
