Every day, we hear sounds all around us—some are soft and some are loud. But do you know that loud sounds can harm your hearing?
Sounds are measured(测量) in decibels(分贝). Look at the chart—some sounds are safe for our ears, but when a sound goes over 85 decibels, it can be harmful to our hearing. To reduce the risk of hearing loss, we should pay attention to the loudness of the noise, the distance we are from it, and how long we listen to it.
Noise levels can be measured by sound-level metres(声级计), but you probably don't always carry one with you. So how can you tell whether noises are too loud or not? Ask yourself: Do you have to raise your voice to be heard? Do you find it hard to hear anyone about a metre away from you? Do noises make your ears hurt or ring for some time? If your answer is YES to any of these, that probably means the noises are too loud.
Headphones are especially tricky. Many people enjoy using them, but they often listen to loud music for too long or keep the volume(音量) so high that even other people can hear the noise from their headphones. These can lead to hearing loss.
Your hearing is a gift. You need it for learning, communicating, and enjoying the world. Once your hearing is damaged, it may never fully recover.
