In the perception of many people, hearing decline in the elderly seems to be a normal physiological phenomenon. However, in fact, this cognitive misconception often leads the public to downplay and overlook the significant harm of age-related hearing loss.
Actually, hearing decline in the elderly (also known as presbycusis) has adverse effects on both the physical and mental health of the elderly. They may experience difficulties in communicating with others, leading to negative emotions such as loneliness and depression. Moreover, they are also at an increased risk of safety accidents due to being unable to hear sounds like car horns clearly.
Currently, there are artificial auditory technologies (such as hearing aids and cochlear implants) that can compensate for hearing loss, and drugs can also be used to delay the progression of presbycusis.
Therefore, both the elderly themselves and their families should seek medical attention in a timely manner when noticing hearing loss in the elderly and choose the most suitable solution to improve the quality of life of the elderly. The manifestations of age-related hearing loss mainly include the following:
Hearing Decline
The typical process of age-related hearing loss is that the hearing level gradually and continuously decreases with age. Hearing loss usually begins at the age of 50, and it is common for both ears to be affected.
I. Can Hear but Cannot Hear Clearly
Sound is generated by the vibration of objects. The higher the vibration frequency, the higher the sound frequency. Under normal circumstances, the human ear can perceive sounds within the range of 20 – 20000 Hz (the unit of sound frequency), among which the human ear is most sensitive to sounds with a frequency of 1000 – 3000 Hz.
Age-related hearing loss usually starts from the high-frequency hearing range. In the initial stage, patients may not be able to hear sounds with a frequency above 2000 Hz clearly. However, there are relatively few high-frequency sounds in daily life, mainly some musical instruments and bird sounds, so the impact on the lives of the elderly is not too great at this time.
As the hearing loss gradually becomes more severe, the frequency range of sounds that the elderly can hear will gradually decrease to the medium and low frequencies (i.e., 500 – 2000 Hz). The normal speech sounds we make usually consist of low-frequency vowels and high-frequency consonants. Therefore, patients with age-related hearing loss may be able to hear someone speaking but cannot hear clearly what the other person is specifically saying. They need the other person to increase the volume and repeat in order to hear clearly.
II. More Difficult to Hear Clearly in Noisy Environments
Young people may have such an experience: even in a very noisy bar, they only need to raise their voices slightly to make others hear them. This is because our ears can distinguish the sounds we need from the noise. However, this ability of elderly patients with hearing loss also declines.
The specific manifestation is that the elderly can hear others speaking clearly in a quiet environment, but as long as the environmental noise is a little louder, they will easily have difficulty hearing and need the other person to speak very loudly to hear clearly.
Tinnitus
Tinnitus is also a common manifestation of age-related hearing loss. The elderly may constantly hear a stable ringing sound, a rushing sound, or a static interference sound. However, different patients may have different feelings or descriptions.
Dizziness
Some structures in the ear are also related to the body’s balance. When hearing loss affects these parts, patients may experience “senile balance disorders.” This may lead to dizziness, balance disorders, and falls in patients.
The above are all common manifestations of age-related hearing loss. If severe hearing loss patients do not take measures, they may develop total deafness, which will greatly affect the physical and mental health of the elderly. Therefore, whether you are an elderly person yourself or a family member, if you have the above-mentioned related symptoms, you should pay attention to them and seek medical treatment in a timely manner.
The market for elderly hearing aids is extremely large. With the aging of the global population, the number of elderly people with hearing loss is increasing year by year. In addition to the natural growth of the elderly population, the increasing awareness of the importance of hearing health among the elderly and their families also drives the demand for hearing aids. Moreover, technological advancements have made hearing aids more comfortable, effective, and user-friendly, further expanding the market. This growing market not only provides opportunities for hearing aid manufacturers but also calls for continuous innovation and improvement to better meet the diverse needs of the elderly.
