The World Health Organization (WHO) has announced that the prevalence of hearing loss in the elderly population over 60 years of age is 50% worldwide. The communication difficulties caused by hearing loss can be very disturbing to the elderly and their families. The elderly themselves, in particular, can experience social withdrawal, become depressed and eccentric because of communication difficulties. Family members, on the other hand, may also misunderstand and even gradually alienate the elderly due to their personality changes. It is evident that intervening in geriatric hearing loss to bring the elderly back to their families and society is an urgent issue to be addressed. The first step for the elderly to take is to go to the ENT department of a regular hospital for examination and consultation once they notice their hearing is significantly declining. The purpose of doing so is to clarify the cause of the hearing loss. This is because some conditions such as otitis media and cerumen blockage can also affect hearing, but these are reversible causes. By removing the cause or trigger, hearing can be restored. If you are diagnosed with senile deafness by your doctor, don’t be nervous and anxious first. Although there is still no special treatment drug for senile deafness, you can take corresponding measures to improve your quality of life. One of the most realistic, effective and convenient ways to improve your quality of life is to get the right hearing aids. After wearing hearing aids, some people may find that they can hear sounds, but they do not understand them, for example, they hear their family members talking to them, but they do not know what they mean. In fact, this is a very common situation. It takes time to learn and get used to hearing and communicating with hearing aid wearers. How long it takes depends on many factors. Age, physical condition, degree of hearing impairment and duration of impairment all affect the length of time it takes. However, the most important thing is how determined the wearer is to regain his or her hearing. Learning to “listen” requires patience and practice, much like learning a new sport or pastime. Not only that, but the wearer must also have reasonable expectations about the level of hearing restoration. In other words, the wearer should not expect to regain 100% hearing once the hearing aid is turned on, but should give themselves time to rebuild their hearing memory and get used to wearing the hearing aid. It is also important to remember that the correct use of scientifically fitted hearing aids will not aggravate the hearing impairment, but hearing aids do not restore the normal hearing of the wearer. Therefore, on the one hand, patients should insist on wearing hearing aids; on the other hand, after using hearing aids, they should also regularly review their hearing to understand whether their hearing continues to decline, and to understand the effect of hearing aids and routinely maintain, repair and adjust hearing aids to make listening more comfortable and convenient. The last point is that patients should learn to maintain their health in order to slow down the development of age-related deafness. Specifically, they should eat less high-fat foods and more foods rich in fiber and protein; they should quit bad habits, especially smoking and alcohol; if they have cardiovascular diseases (such as hypertension) and diabetes, they should also pay attention to control them so as not to affect the microvascular circulation and aggravate the degree of hearing loss. In addition, patients should also avoid exposure to noise as much as possible; when taking certain drugs, they should pay attention to whether those drugs have obvious ototoxicity. Hearing aids are not ordinary commodities. Hearing aids purchased in stores without professional matching not only cannot help, but may also damage hearing due to increased noise output. The most suitable hearing aid must be chosen by the fitting technician according to the hearing curve and the computer software, just like the optical examination before the glasses. The choice of hearing aid is determined by the degree of hearing loss and financial ability. Nowadays, there are many hearing aid brands and styles such as box, behind-the-ear, in-the-ear, canal and deep ear canal, etc. The price ranges from several hundred dollars to several tens of thousands of dollars. According to our years of experience in helping the elderly with hearing aids, we can refer to the following points: 1. Try to use digital hearing aids: Although the price of digital hearing aids is more expensive than analog machines, and the cheap ones cost about two thousand dollars, the digital machines have good speech focusing ability and low noise, and can be adjusted more carefully according to the listening environment. 2, try to use the behind-the-ear type: Although in-the-ear and canal hearing aids are small in size, they are not easy to be noticed after use. However, the power range of behind-the-ear hearing aids is larger and suitable for different degrees of hearing loss; the batteries and buttons are larger and easier to operate, which is especially suitable for the elderly. 3, fitting, to try out in a variety of environments: the elderly are slightly less adaptable to new things, before buying hearing aids, be sure to understand the role of hearing aids and the advantages and disadvantages; try them on and fully feel the real effect of hearing aids in different external environments. In addition, let the elderly understand in detail about the correct use of hearing aids, so that they can better accept hearing aids. 4. Try to choose slow compression technology: fast compression technology and slow compression technology are the more advanced speech compression technology at present. The hearing loss of senile deafness is characterized by high-frequency hearing loss as the main sensorineural deafness, although the pure tone hearing loss is light, but the speech recognition ability is obviously reduced; there is often the phenomenon of cochlear reverberation, so that patients “can’t hear in a low voice, loudly suspicious of people noisy”. Therefore, patients with senile hearing impairment feel better with slow-compression hearing aids than with fast-compression hearing aids. However, although slow compression alone maintains a linear relationship with speech in a stable environment, it can lose some of the speech information due to the long activation and release time in the face of sudden changes in the sound environment, which is very obvious when moving from a noisy to a quiet environment. Now there is also a new hearing aid which adds another fast compression technology (sound stabilizer) to the slow compression technology, using the slow compression technology in a stable environment and the temporary fast compression technology in a sudden change environment. This combination will ensure the continuous audibility of speech and is especially suitable for elderly applications.
