Hearing Aid Selection in an Older Adult With Dexterity Limits
A 74-year-old retired schoolteacher attends with bilateral hearing difficulty that has worsened over 3 years. She reports trouble following grandchildren and conversation in a noisy bridge club, and often asks people to repeat. Audiometry shows bilateral mild-to-moderate sloping sensorineural hearing loss: right PTA 43 dB HL, left PTA 47 dB HL; word recognition is 88% right and 84% left at 80 dB HL. Tympanometry is normal. She uses an iPhone daily, watches TV with captions, and has rheumatoid arthritis affecting both hands, with weak grip and difficulty handling small objects. She wants 'invisible' in-the-canal hearing aids because she is self-conscious. She once borrowed a friend's over-the-counter earbud and found it 'tinny and whistling'. She lives alone, drives, and attends medical appointments independently.
1. What hearing aid style and features would you recommend, and how would you justify them to her?

Recommend a bilateral receiver-in-canal or behind-the-ear fitting with rechargeable batteries, Bluetooth connectivity, a telecoil if available, directional microphones, and noise-reduction features. The justification is functional, not cosmetic. Her sloping loss needs gain across frequencies, and a RIC/BTE can provide appropriate amplification with less occlusion and feedback than a deep in-the-canal device. Her rheumatoid arthritis makes tiny batteries, small controls, and deep insertion difficult; a rechargeable device with a simple charging dock and a larger volume control is more manageable, although she should still be shown how to handle the receiver and dome. Bluetooth would let her stream phone calls and television audio, matching her daily routines. An IIC device would be a poor first choice: it is hard to insert, uses small batteries, limits directional microphone and Bluetooth options, and is more prone to occlusion and feedback in a sloping loss. Acknowledge her wish to be inconspicuous, show her a discreet RIC, and explain that a successful fitting depends on audibility and comfort rather than invisibility. Offer a trial and involve her in the decision.
2. Outline a verification and validation plan for the fitting.

Verification should begin with real-ear measurement, not first-fit software settings. Use a validated prescriptive target such as NAL-NL2, measure real-ear aided response across frequencies, and adjust gain to match targets while checking for feedback and occlusion. Speech mapping in quiet and in noise can confirm audibility of soft, average, and loud speech. Validation should include aided speech-recognition testing in quiet and background noise, plus a self-report measure such as the Client-Oriented Scale of Improvement or a hearing-handicap inventory. Ask her to identify two or three specific listening goals, for example following one grandchild in a quiet room and hearing across a table at the bridge club. Arrange a follow-up at about 2 weeks and again at 6 weeks, with intermediate telephone support if needed. At follow-up, check physical fit, battery or charging routine, dome or earmould condition, and real-world use. Counselling should cover realistic expectations, gradual introduction of the aids, communication strategies, and the fact that background noise remains difficult even with good devices.
3. She insists on invisible in-the-canal aids after counselling. How should you proceed?
Read the worked answer
Respect her autonomy but avoid colluding with a fitting you expect to fail. Restate the specific trade-offs in concrete terms: difficulty inserting and removing the device with arthritic hands, small battery changes, greater occlusion of her own voice, higher feedback risk with her sloping loss, and fewer connectivity options. Offer a compromise such as a small RIC with a custom earmould or a slim-tube fitting, and demonstrate the size and handling demands. If she still insists, document the discussion, her stated preference, and the risks she has accepted, then consider a time-limited trial with clear review criteria rather than an outright refusal. During the trial, monitor insertion, feedback, comfort, and whether she can manage the device independently. If the trial confirms poor handling or unacceptable sound quality, move to the recommended style with her agreement. Do not let a cosmetic preference override safety and function, but do not paternalistically dismiss her concerns; shared decision-making with documented informed consent is the defensible path.
