Noise-induced hearing loss–Will noise-induced hearing loss decrease in the future?
We know that with age, the probability of hearing loss is also greatly increased, and hearing loss is proportional to age, which is the basic feature of senile hearing loss. At the same time, we have always believed that hearing loss has become more serious over time, such as2015Year30Older men’s hearing should be better than1998Men of the same age in the year are more severe, but the latest research shows that this time relationship of hearing loss is not the case. Recently American scholars are analyzing3753Age at48岁到94At the age of the population, hearing loss was found to increase with age, but decreased over time.
In their research,48岁到59Among the people between the ages, there are21%Incidence rate;80Among people over the age of90%The incidence rate, once again proving that older people, the higher the prevalence of hearing loss. Interestingly, this is a10Years of follow-up studies, in other words, each year they receive a hearing test and compare it to the original hearing threshold.10After the year, people who originally had normal hearing thresholds now have at least37%There has been hearing loss. However, the descendants of these people are10During the middle of the year, their children’s hearing did not deteriorate as they did with time. For these ages21岁到34The population between the ages, the incidence of hearing loss is reduced to3%! In contrast, age is64岁到84Between the ages, the incidence of hearing loss has increased to43%. This shows that people of the same age have different rates of hearing loss at different times; but in any case, the same person, the older, the incidence of deafness is monthly.
Obviously, the above data is quite meaningful, that is, if the person born later is counted from the birthday time, the hearing loss rate is lower. such as1950The proportion of people born in the year who suffer from deafness is only1930Born50%. Why does this happen? They think there are two factors: one is from20Since the beginning of the century, most people’s work has changed from blue-collar to white-collar, receiving less noise exposure. Second, due to the improvement of noise standards and the strengthening of professional disease protection measures, the possibility of noise-induced hearing loss is reduced.
For the above research results, the Chinese audiology network Han Dongsheng editor-in-chief believes that the fact that hearing protection is effective in reducing the incidence of hearing loss is also valid, and the long-term tracking experiment results also confirm this point. Therefore, if we start now, we will start to stay away from high-intensity sounds and use ear protectors properly. We are fully capable of reducing the incidence of deafness. Education is still the key!
