How are CI's different from hearing aids? correct answers Hearing Aids can be updated and uses the normal auditory pathway for all HL but Cochlear Implants are only for SNHL and only use the technology available at that time •Hearing aids correct answers most will do 99% good w/them send sound through normal pathway of sound acoustically amplify sound focus on speech understanding •Cochlear Implants: correct answers --people that dint do well w/HA because they dint meet persons nee...
