Match the Technology to the Access Problem
| Technology | Core function | Common decision point |
|---|---|---|
| Hearing aid | Amplifies and processes acoustic input | Usable residual hearing and expected benefit from amplification |
| Cochlear implant | Converts sound to electrical stimulation of the auditory nerve | Severe hearing difficulty with limited appropriately fitted hearing-aid benefit; candidacy is individualized |
| Bone-conduction device | Sends vibration through bone to stimulate the cochlea | Conductive or mixed loss, ear-canal limitations, or selected single-sided deafness cases |
| Remote microphone/DM system | Sends a talker's signal directly to a receiver | Distance, noise, and reverberation reduce the signal-to-noise ratio |
| Hearing assistive technology | Improves access for a particular task or environment | Telephone, television, classroom, workplace, public venue, or alerting need |
| Alerting device | Converts an event to visual, tactile, or amplified signal | Doorbell, alarm, infant cry, emergency notification |
| Telecoil or wireless streaming | Feeds a phone, TV, or room hearing loop straight into the hearing aid or implant | Telephone use, television, and venues with a hearing loop |
Hearing aids amplify; cochlear implants do not simply make sound louder and do not restore normal hearing. Device selection, candidacy, fitting, verification, and audiologic monitoring are led by an audiologist and medical team as appropriate. SLPs contribute communication assessment and habilitation/rehabilitation.
