A common sensory problem is hearing loss. Bilateral hearing loss affects over 14.3% of the American population (12+ years old), or around 38.2 million people. According to the CDC, one and a half percent of the infants screened in the United States in 2019 have some hearing loss. It is possible to fit many people with hearing loss with hearing aids; the success rate depends on the severity of the loss. A cochlear implant may allow some people to hear again if their hearing loss is too severe to be helped by traditional hearing aids. A cochlear implant is an implant that can transform auditory signals into an electrical signal. The cochlear modiolus’s spiral ganglion cells receive this electrical signal with electrodes. As of December 2019, the number of registered cochlear implant devices in patients worldwide reached about 736,900. Unfortunately, many people who could benefit from cochlear implants do not get them because healthcare facilities either lack the funds or do not know who would be a good candidate.
