The 19 pages that link to Hearing aid, each with the reason it gives.

• Assistive technologyBroader topic: Hearing aids illustrate personal technologies for accessing sound.

• Alexander Graham BellRelated: Bell’s research into hearing and sound transmission helped establish a lasting area of interest.

• Hearing lossRelated: It can improve access to sound when amplification is useful.

• Speech perceptionRelated: Its signal processing aims to improve access to speech cues.

• Cochlear implantCompared with: Unlike an implant, it relies on functioning inner-ear sensory cells to convey amplified sound.

• Conductive hearing lossRelated: Amplification can help when conductive loss persists or surgery is unsuitable.

• Sensorineural hearing lossRelated: Amplification can improve access to sound when residual hearing remains.

• AudiometryRelated: Audiometric results help set its frequency-specific amplification.

• TinnitusRelated: Amplification may reduce tinnitus prominence when hearing loss is also present.

• Noise-induced hearing lossRelated: Amplification can improve access to sound when noise damage causes lasting impairment.

• OtotoxicityRelated: It may improve communication when ototoxic hearing loss cannot be reversed.

• PsychoacousticsRelated: Effective amplification must account for both hearing thresholds and perceived sound quality.

• Auditory systemRelated: It compensates for some forms of reduced sensitivity by modifying incoming sound.

• AudiologyRelated: Audiologists select and fit these devices to address hearing loss.

• Outer earRelated: Many hearing aids deliver amplified sound through or near the external auditory canal.

• PresbycusisRelated: Hearing aids can improve access to speech and environmental sounds when presbycusis limits audibility.

• DeafnessRelated: Hearing aids can improve access to sound when residual hearing can be usefully amplified.

• Point-Contact TransistorBroader topic: Early transistorized hearing aids made amplification portable and less power-hungry.

• Primary cellRelated: Many hearing aids use compact zinc–air primary cells for their energy supply.
