What are the effects of mild hearing loss on a daily basis?

The degree of hearing loss is divided into the following categories: (decibels, or dB).

1. Normal hearing: -10 25 decibels.

Analyze general sounds and language clearly.

2. Mild hearing loss: 26 40 dB It is difficult to distinguish small sounds, such as the sound of wind blowing in the woods.

3. Moderate hearing loss: 41 55 dB Have auditory difficulties in daily language, feel blurred in conversation, and begin to need the help of hearing aids.

4. Moderate to severe hearing loss: 56 70 decibels.

5. For loud conversations? Car sounds are still muffled, and hearing aids are more helpful.

6. Severe hearing loss: 70-90 dB or more. For shouting and loud sounds, such as car horns. Drums only respond, and hearing aids help more.

7. Severe hearing loss: greater than 90 decibels, it is usually extremely difficult to feel the existence of sound, and it is necessary to rely on hearing aids to feel the vibration force of sound.

People with mild hearing loss can listen in a quiet environment, but when the environment changes slightly, the negative effects of mild hearing loss follow.

1.Although speech sounds can be heard at close range, it is more difficult to hear when the speaker is more than 3 meters away;

2.Listening to softer sounds in a quiet environment requires pricking up your ears, narrowing the distance, and concentrating to hear clearly, such as whispering, the rustle of leaves in the wind, the sound of birds, the sound of water droplets, etc.;

3.It is more difficult to listen softly in a noisy environment, and it is even more difficult to distinguish small sounds;

4.Listening to others will listen to the "fork", and sometimes it needs to be repeated by others to hear clearly;

5.With hearing loss, it can affect the physical and mental health of the patient. For example, avoiding contact with people, being suspicious and suspicious, having a bad temper and being irritable.

Hearing loss is a disease that workers consider to be a disability. Whether illness or disability, it is always unfortunate. Life-threatening problems are terrible, but non-life-threatening problems are not necessarily terrible.

Hearing loss is harmful to the human body and cannot be ignored

First, hearing impairment; Under normal circumstances, our hearing can distinguish hundreds of thousands of nuances of sound. Once an obstacle arises, the problem is more serious than you think. If you can't hear the car horn, you can easily get into a traffic accident; More importantly, not being able to hear can make us feel insecure.

Second, communication barriers: the problem of hearing loss is more of a communication problem; The hazards of hearing loss are also more derived from communication disorders. Without the support of language, they will not be able to communicate normally with the society around them, which will eventually lead to irreversible and serious consequences.

Third, psychological disorders: communication disorders will eventually cause psychological disorders, or affect mental health, which is inevitable for most people with hearing loss.

Hearing loss can occur for several reasons:

Sudden hearing loss caused by a viral infection or embolism of blood vessels in the inner ear.

Infectious hearing loss caused by infectious diseases such as meningitis, measles, typhoid, etc.

Detonation hearing loss caused by trauma or knocking, noise, etc.

Experts warmly remind: for hearing loss can not be ignored, do not be pessimistic and negative, any disease as long as the positive ** is possible to recover, therefore, if there is ear discomfort or as well as the detection of hearing loss patients, or to the hospital in time**.

Hearing loss is also known as deafness or hearing level. It is the number of decibels above the normal hearing threshold of the human ear at a certain frequency. Age-related hearing loss is called presbycusis; Hearing loss due to socio-environmental noise (other than influences such as age, occupational noise, and disease) is called social deafness; Hearing loss caused by occupational noise is called noise-induced hearing loss.

Noise-induced decreased hearing sensitivity, increased hearing threshold, auditory dysfunction, and even hearing loss are collectively referred to as hearing loss. It can be divided into two types: temporary and permanent.

Temporary hearing loss.

Tinnitus and hearing loss caused by a short period of time in a strong noise environment, the hearing threshold rises by 10dB, and the hearing is restored within a few minutes after getting rid of the noise, which is called auditoryadaptation; If the noise is applied for a long time, the hearing threshold rises by 15 to 30 dB, and it takes several hours or even days for hearing to recover, which is called auditory fatigue or noise-induced temporary threshold shift (NITTS or TTS), which is commonly referred to as temporary hearing loss.

Permanent hearing loss.

The irreversible damage to hearing caused by noise is called noise-induced permanent threshold shift (NIPTS or PTS), also known as permanent hearing loss. PTS caused by industrial noise is mostly developed from TTS, and there is a chronic development process that forms a V-shaped or U-shaped hearing loss at 3000 6000 Hz on the audiogram, the so-called 4000 Hz Listening Valley (DIP). High-frequency "hearing valley" is a typical feature of hearing loss caused by occupational noise, and it is also a precursor to noisy deafness.

PTS usually develops symmetrically, often with tinnitus, and sometimes hearing loss for high-frequency sounds, but has no significant effect on verbal conversation. If it continues to develop, the hearing valley deepens and expands to both high and low frequencies until noise-induced deafness and hearing loss occur.

Hearing impairment first has an impact on people's work, life and communication: (1) Leaders and colleagues cannot hear the conversation clearly, and they are always worried for fear that others will misunderstand or affect their work. (2) Family members often "ignore and ignore" to answer questions, which affects the harmonious atmosphere at home.

3) Playing ** to watch TV and not hearing clearly, turn on the volume widely, which affects the rest of family members and neighbors. (4) Always can't hear, the content of sound information input to the brain is reduced, and the brain's ability to distinguish sound information decreases, which further aggravates the hearing impairment, which is manifested as the speed of speech is accelerated, and the brain has no time to distinguish and process sound information, and often goes to the sound and does not understand the meaning. As a result, deafness is less likely to communicate with others and hears less, often resulting in loneliness, depression or grumpyness, reduced quality of life, and the elderly are also susceptible to senile dementia.
