A cochlear implant is an electronic device designed to replace the function of the human cochlea, while a hearing aid is a small device that amplifies sound for people with hearing loss. The differences between the two generally lie in the intended user, cost, method of use, working principle, and lifespan.
Target Users
Cochlear implants are typically suited for individuals with severe to profound hearing loss. In contrast, hearing aids are designed for people with mild to moderate hearing loss.
Cost
Cochlear implants are more expensive due to high research and development costs, typically ranging from $11,000 to $27,400. Hearing aids, depending on the type and method of sound conduction, range from $8,200 to $11,000.
Usage Method
Cochlear implants require a surgical procedure performed by a team of specialists, including otolaryngologists, audiologists, and rehabilitation experts, to assess the patient’s condition and implant the device. On the other hand, hearing aids do not require surgery; they are simply worn externally on the ear or in the ear canal.
Working Principle
A cochlear implant works by using electrical currents to stimulate the auditory nerve, effectively bypassing damaged parts of the ear. Hearing aids, however, amplify external sounds to compensate for hearing loss in the affected ear.
Lifespan
The lifespan of a cochlear implant is typically around 70 years, and with proper care, it rarely experiences damage. Hearing aids have a lifespan of about 5 to 10 years, though custom models can last up to 15 years with proper protection and maintenance.
Both cochlear implants and hearing aids should be chosen carefully based on individual needs and in consultation with a medical professional, to avoid negative impacts on daily life.
