I heard that using headphones can damage your hearing. Is this true?
Nowadays, teenagers, including office workers, have become accustomed to listening to music on the road. Music can cultivate one's sentiments, relax one's mood and calm down irritable emotions. Wearing headphones to listen to music or listen to English learning is now everywhere, and it is also a favorite thing for everyone. However, how many people pay attention to the harm caused by wearing headphones for a long time, and how many people know about it?
With the emergence of mobile phones, headphones are getting closer and closer to us. Frequent wearing of headphones will have an impact on the auditory system. Severe cases can even cause permanent deafness when the volume heard by human ears reaches 85 decibels. Longer periods can cause hearing fatigue when the volume is raised above 110 decibels. Enough to cause the death of hair cells in the human inner ear. Severe cases can also cause irreversible hearing damage. The volume of headphones is generally around 84 decibels. Some high frequencies can reach 120 decibels. Such a volume has a great stimulating effect on the ear nerves. Hearing loss can occur over time without affecting the frequency of speech we use in daily communication. So it is often ignored in the early stages. Only when hearing loss and speech frequency hearing loss reach a certain level will subjective hearing impairment occur.
Therefore, the impact of using headphones to listen to things on young people usually does not appear until many years later, so people today generally do not feel the harm. After a person puts on headphones, the outer ear is almost in an occluded state, and high-volume audio sound pressure directly enters the ear and is concentrated on the thin eardrum. At the same time, the distance between the earplug's vibrating membrane and the eardrum is very close, and the sound wave propagation range is small and concentrated, which causes greater stimulation to the auditory nerve of the eardrum. Over time, it can easily cause tinnitus, insomnia, headache, ear fullness and progressive hearing loss. Frequent wearing of headphones can also cause some systemic discomfort, such as dizziness, nausea, etc. In the long run, it is easy to develop inattention, slowed thinking reaction, memory loss, and even abnormal psychological and emotional reactions such as irritability and lack of patience.

In places with loud noises such as buses or streets, it is best not to use headphones to listen to music, because in order to cover the noise, people often unconsciously increase the volume, which will cause greater damage to the ears. At the same time, you must not listen to it for a long time, preferably no more than 1 hour at a time. In addition, don't listen while sleeping, otherwise the earplugs will be caught between the pillow and the ears, which will cause damage to the eardrums; if you fall asleep while listening, the damage will be more obvious when the ears are in a dormant state.
Hearing experts remind that people who often wear headphones to listen to music should master the "60-60" principle, that is, when listening to music, the volume should not exceed 60% of the maximum volume. %, do not listen continuously for more than 60 minutes.
