Description
technical field [0001] The invention belongs to the field of earphone equipment, and in particular relates to a special noise reduction earphone for the elderly. Background technique [0002] We all know that our sense of hearing is limited. Just like setting the temperature of water as 0 degrees Celsius when it freezes, audiologists artificially define the sounds of several different frequencies that normal young people can just hear as hearing level 0 (0dBHL). Normal people can barely hear the sound of hearing level 0. The conversation in a quiet environment is about 60 hearing level, which sounds soft and suitable. Due to the growth of age, the auditory organs of the human body will slowly and progressively age together with other tissues and organs of the body, and hearing loss will occur, so the elderly have hearing problems. At present, the elderly in my country generally use hearing aids when they suffer from hearing loss. However, hearing aids are expensive, and t...
