Because the elderly are older, the need for work and study is reduced, and the requirements for hearing AIDS will be relatively lower than those of children and young people. Most elderly people are suitable for an economical hearing aid of about 3,000 yuan or a mid-range hearing aid of about 5,000 yuan. If the elderly only want to solve basic conversation problems at ordinary times, and their economic situation is average or they are unwilling to spend more money on hearing AIDS, they can choose a universal hearing aid of about 1000. Some elderly people have poor hearing (such as heavy hearing, complicated hearing curve and low speech recognition rate), and some elderly people have high hearing needs (such as listening to Beijing opera, listening to radio, reading books, watching TV, chatting online and making phone calls). ). In this case, it is recommended to choose the medium and high-grade Baolang TV hearing aid, and the ears should be synchronized and balanced.
