In daily life, some elderly people like to turn up the volume very high when watching TV or using their phones; When chatting with others, the voice becomes louder and often requires the other person to repeat several times to understand the meaning... If these situations occur, elderly people are likely to suffer from hearing loss. Elderly hearing loss refers to the decline in auditory function caused by factors such as aging, ear diseases, genetics, noise damage, ototoxic drugs, metabolic disorders, and unhealthy lifestyle habits. Many people believe that having an old ear is normal. In fact, not being able to hear is not just about "listening". Some elderly people gradually refuse to communicate with others because they cannot hear what others are saying clearly or need them to repeat it multiple times, fearing they may misunderstand their meaning. Over time, elderly people may experience feelings of loneliness, leading to mental and psychological problems such as anxiety and depression. Hearing loss can also increase safety risks, such as not hearing a car horn on the road, which may lead to accidents due to inability to dodge. In addition to aging, chronic diseases such as hypertension and diabetes will also aggravate hearing loss of the elderly, and these patients should pay special attention. The frequency range that the human ear can perceive is between 20-20000 hertz, and the frequency range for daily verbal communication is generally between 500-3000 hertz. The sound of mosquitoes and rubbing fingers is a common high-frequency sound, while the buzzing sound emitted by refrigerators and range hoods during operation is a low-frequency sound. Elderly hearing loss often first appears in the high-frequency range and gradually expands to the mid low frequency range. How to know if your listening is good or not? Here are several commonly used simple self testing methods: rub your thumb and index finger against your ear and carefully identify if you can hear the sound of finger twisting; Can you hear the "click" sound of the second hand when holding a watch (quartz or mechanical) to your ear; Rubbing plastic bags, knocking on tables, etc., can you hear these sounds. If you cannot hear or hear others clearly when communicating with them in a noisy environment, and need to turn up the volume very high when watching TV or using your phone. After using the above self testing methods, some sounds may not be heard clearly, which may indicate hearing loss. It is recommended to seek medical attention as soon as possible. (New Society)
