The hearing of adults is usually affected when the sound reaches 85-90 decibels. If you are frequently exposed to noise, the noise volume is above 85 decibels, it can easily lead to deafness, which is manifested as sensorineural deafness. Since the hearing level has a lot to do with the body’s own auditory system and living environment, each person’s hearing condition needs to be tested by an ENT doctor or audiologist through a pure tone audiometer. When people are in different decibels of sound, there may be the following feelings: 1, 0-20 decibels: the sound is very quiet, almost so that people can not feel; 2, 20-40 decibels: people will feel more quiet, can hear more clearly; 3, 40-60 decibels: in general is the volume of ordinary indoor conversation; 4, 60-90 decibels: some noisy, there may be a slight hearing nerve damage. Above 70 decibels will make people irritable and inattentive. Noise if it reaches 80 decibels or more intensity, persistent noise long-term stimulation, can cause damage to the inner ear spiral apparatus and spiral nerve, and cause noise deafness; 5, 90 decibels or more: lead to human hearing damage, and even cause deafness. Patients with hearing problems should pay attention to protecting their ears, not to be in a noisy environment for a long time, avoid wearing headphones for a long time to listen to songs, and can massage the relevant acupuncture points under the guidance of Chinese medicine practitioners to protect their hearing.
