A hearing aid is a soft-washer device designed to enhance hearing for a person with hearing impairment. Hearing aids can be classified as medical therapeutic devices in all countries, and controlled by the corresponding regulations. Medical devices need to be certified by recognized agencies of the relevant medical profession such as the American hearing association (AHAS). Medical devices also need to comply with certain quality standards set by the US department of health. The Federal government has mandated that every such device must have a label that states the presence of any advance hearing device technologies or a hearing aid component, which requires a hearing aid manufacturer to include a label with the relevant details.
Hearing Aids Review
Medical hearing aids contain many components such as directional coupler, electronic transducer, diaphragm, head gear, sensorineural hearing loss device, and the like. Typically, BTE (behind the ear) is used for people suffering from conductive hearing loss caused by the nerves or the hair cells in the inner ear are damaged. SED (subsonic electronic signal) is used for people suffering from sensorineural hearing loss due to damage to the inner ear. Some models also incorporate the above components in addition to electronic circuitry to enhance the performance.
The advantages of wearing hearing aids are varied depending on the type of problem. If you suffer from conductive deafness, then BTE is an ideal choice since it enables the user to communicate better. If you suffer from sensorineural deafness, then a BTE could be more suitable since it allows the wearer to hear better. If you wear a BTE, you will be required to have regular checkups and evaluations by your audiologist, who will determine if your unit needs to be replaced. However, a sensorineural hearing aid might be the best option if you want to enjoy a better quality of life.
