Listening to the radio for a long period of time is not harmful if the sound is moderate, but if the sound is loud it may cause damage to your hearing. Under normal circumstances, if the sound of the radio is small or moderate, even if it is used for a long period of time, it will not cause any harm, and there will not be any damage to the hearing. However, if some people use the radio at a higher volume, the sound waves will directly affect the tympanic membrane and reach the inner ear, which may cause damage to the hair cells of the cochlea, thus affecting hearing, and may even cause deafness, tinnitus and other symptoms. If the user wears headphones for a long time to listen to the radio, the degree of hearing damage will increase, and may also induce otitis externa and other infectious diseases, this situation requires medical treatment.
