Wear earphones for a long time and be wary of "headphone disease"

 　　What is headphone disease? What problems might occur when using headphones? How to minimize the earphone damage to hearing?

　　As the name suggests, earphone disease should be a collection of a series of uncomfortable symptoms caused by wearing earphones. Since the birth of the Walkman, earphones have entered thousands of households. The superiority of earphones is self-evident. Users can enjoy the sound alone without disturbing other people, and can listen to the sound any place they want. Very much in line with the characteristics of modern people-advocating personal space and not disturbing others. However, with the expansion of the time and scope of earphone use, more and more problems have attracted people's attention, and these problems have also formed the concept of "headphone disease".

　　What problems might occur when using headphones? What are the reasons for these problems? How can we avoid these problems while enjoying the sound?

　　At present, earphones are divided into two types according to the way they are worn: one is the embedded ear canal type, and the other is the ear canal type. The function of human ears is to collect sound and fine-tune the intensity of sound waves. The function of the ear canal is more complicated. It not only collects sound waves and enhances sound wave energy, but also has the ability to clean itself. The latter maintains a nearly aseptic environment in the external auditory canal through the secretion of the cerumen, and the movement of the temporal-mandibular joint will discharge the cerumen in the auditory canal out of the external auditory canal. Of course, these functions can only be achieved when the external auditory canal maintains a normal physiological state.

　　Obviously, the ear-wrapped earphones conform to the general sound characteristics and do not affect the function of the ear canal. Structurally speaking, the effect is very small. The embedded ear canal type has more problems due to direct contact and compression of the external auditory canal: firstly, it is possible to push the cerumen of the external auditory canal into the depths of the external auditory canal. Secondly, it affects the movement of the temporal-mandibular joint and pushes the cerumen of the external auditory canal outwards. Function, the friction between the earphone and the skin of the external auditory canal will cause inflammation of the hair follicles, and the earache and ear swelling will be caused by the earphones pressing the external auditory canal for a long time. Moreover, the earphones are not suitable for cleaning. As the wearing time is prolonged and the wearing is changed, it may cause the spread of diseases. Therefore, in order to avoid the above situation, it is recommended not to wear the earphones for a long time. Generally half an hour is more appropriate. When wearing it, try not to do chewing and other activities of the temporal mandible joint. It is best to use ear-wrapped earphones.

　　The ear is a highly sophisticated organ. It can perceive sounds in the range of 20 to 20,000 Hz. It has a sophisticated system that adjusts the perception according to the level of the sound, so as to avoid damage to the ear. Of course, with age, the function of the ears will tend to degenerate. Excessive sound stimulation has the greatest impact on the ears. Due to the development of industrialization and the production of machinery, the intensity of sound produced by humans has far exceeded that of natural sounds. From the perspective of the evolutionary theory of survival of the fittest, our ears have an impact on natural sounds. The adaptation is not enough to cope with the intensity of the sound produced by humans and achieve the effect of protecting the ears. This makes our ears relatively more and more fragile. The use of headphones aggravated this link.

　　The ear is the only organ in the human body that monitors the surrounding environment in an all-round way. It plays an important role in understanding the surrounding environment and avoiding danger. The wearing of the earphone almost loses this important function. Most people use earphones when walking, running, or riding in transportation, which actually puts us in a very dangerous situation, because at this time it is equivalent to turning off the function of monitoring the surrounding environment in all directions, and the danger outside the line of sight is not very good. If the ground is detected, accidents are easy to happen. Therefore, it is recommended not to use headphones in unfamiliar and complex environments, or to reduce the volume as much as possible during use.

　　Why does the use of headphones affect hearing? First of all, earphones, especially ear canal embedded earphones, transmit sound directly close to the tympanic membrane, and the energy is relatively stronger. However, the current pop music, percussion and other decibels are very high, and it is easy to ignore the strong sound while enjoying music. Ear discomfort; second, when using headphones, the surrounding noise is often relatively large. Use headphones on the basis of this background noise. In order to eliminate the interference of background noise, it is natural to increase the sound intensity and make the ears at too high sound stimulation Among. Because this entertaining music makes people feel happy, it is easy to listen for a long time, so that the ears are exposed to excessively high sound stimulation for a long time. If the inner ear is not properly rested, there will be temporary hearing loss, which will lead to permanent hearing loss over time. Hearing loss caused by strong sound often damages high-frequency hearing first, and the hearing loss of this frequency is not easy to detect, so it is difficult to detect early, so it is ignored. It is not discovered until it is very serious and affects language communication. It's too late.

　　How to minimize the earphone damage to hearing? First of all, the volume should not be too high, and do not pursue the thrill of strong stimulation. Generally 60-70 decibels are more appropriate, and remember that the louder the sound, the shorter the continuous listening time; secondly, don’t wear headphones in a noisy environment. ; Finally, don't wear headphones to listen to music to sleep.
