Putting on headphones and listening to music is a good way to kill boring time for people who take public transportation to and from get off work or school every day. It does not affect others and can entertain themselves. However, experts warn that wearing headphones for a long time, especially the habit of listening to music at high volume, can lead to progressive hearing loss. 1. Pay attention to volume and usage time People who experience dizziness, tinnitus, ear blockage, or wear headphones for more than 3-4 hours a day are at high risk of hearing loss. Experts suggest that the volume of headphones should not exceed 2/3 of the maximum volume of the player, and your ears should be given a full rest after listening for 30-40 minutes each time. The volume of the headphones should be as close to that of a normal person speaking, preferably 50-60 decibels, and no more than 85 decibels; Adults should not wear headphones for more than 3-4 hours a day, and minors should not wear headphones for more than 1-2 hours a day. And after wearing headphones for 30-40 minutes each time, the ears should be given a full rest. 2. Headphones are better than in-ear headphones. It is recommended to choose the former for long-term use. For people who need to wear headphones for a long time, it is recommended to choose headphones. In-ear headphones have a small sound contact area and exert a higher pressure inside the cochlea; headphones have a large contact area and lower pressure, which causes relatively less stimulation to the cochlear ciliary cells and is safer. In addition, sound can be received through the skull in addition to air conduction. Especially when students are doing listening exercises, if they get tired of listening, they can wear headphones on their skull. This will allow them to hear the sounds while reducing the stimulation to the cochlea. 3. The environment in which you use headphones is also important We often see some young people on noisy streets listening to music while walking, riding in a car, or even riding a bike. In fact, using headphones in a quiet environment will cause the least damage to the ears. Secondly, listening for a while before going to bed can also reduce the damage. Using headphones on a noisy subway or while riding in a car will cause the most damage to the ears. |
