When someone speaks loudly, you just can't hear what they are saying?

If you find that your speech is slurred and you can hear the sound but not clearly, it may be that your hearing has declined. Hearing loss does not mean that you cannot hear sounds at all. Often, you only hear part of the sound and cannot hear other parts. This is why "I can hear other people's voices, but I just can't hear them clearly." Technically, this is usually caused by high-frequency hearing loss.

If you suffer from high-frequency hearing loss, although you may not be able to follow conversations in a quiet environment, you will be relatively better. In noisy environments, this problem becomes obviously serious. When you can't hear clearly or understand what others are saying, you will pay more attention to listening, and many times you will feel very tired and frustrated. Over time, he became reticent and unwilling to communicate with others.

If you have hearing loss, you should go to a regular hearing aid center for a professional hearing test to determine the nature of the hearing loss and then solve the problem. Fitting a suitable hearing aid can delay hearing loss and effectively improve your hearing. Difficult.

As age increases, the hearing organ begins to age and degenerate. The older you get, the more likely your hearing is to deteriorate. This is also called "presbycusis" , mainly high-frequency decline in the early stage.

The natural resonance peak of the external auditory canal is 2000Hz-4000Hz. Within this range, the ear canal has the greatest sound gain. Therefore, hearing loss is most likely to occur in the frequency range of 4000Hz-6000Hz, up to the full frequency range. For example, if you wear headphones for a long time, the longer the time, the more serious the damage will be.

The perception of high frequencies is mainly carried out by the outer hair cells of the cochlea. The basilar membrane hair cells around the base of the cochlea contain lower antioxidant enzymes than the apical hair cells, so the hearing loss caused by ototoxic drugs such as aminoglycoside antibiotics shows a "V"-shaped decline. In addition, genetic factors and ear diseases can also lead to hearing loss.

Even if your hearing is damaged, you should not give up on yourself. There are effective ways to prevent further hearing loss. Make regular scientific observations to understand the trend of hearing loss and take targeted measures. Users who need Hearing Aids should be fitted and adjusted in time to prevent their ears from being deprived of speech stimulation for a long time, causing speech disorders and consuming more recovery time.
