In a 78-year-old woman who is startled by moderately intense sounds, what is the appropriate evaluation and management?

Evaluation and Management of Sound Hypersensitivity in a 78-Year-Old Woman

This patient requires formal audiologic evaluation to assess for age-related hearing loss (ARHL) and to identify any atypical features that would necessitate otolaryngology referral, particularly asymmetric hearing loss, conductive components, or poor word recognition. 1

Initial Assessment Approach

The exaggerated startle response to moderately intense sounds in this elderly patient suggests a phenomenon called hyperacusis or recruitment, which paradoxically can occur with hearing loss. This requires systematic evaluation to distinguish between:

• Age-related hearing loss with recruitment (abnormal loudness growth where soft sounds are inaudible but moderately loud sounds become uncomfortably loud)
• Conductive or mixed hearing loss requiring medical/surgical intervention
• Asymmetric sensorineural hearing loss warranting imaging to exclude retrocochlear pathology

Specific Evaluation Steps

Audiologic Testing Required

Obtain comprehensive audiometry that includes:

• Pure tone thresholds to assess degree and symmetry of hearing loss
• Speech discrimination testing to evaluate word recognition scores
• Tympanometry to identify middle ear pathology
• Assessment for recruitment/hyperacusis through uncomfortable loudness levels

Red Flags Requiring Otolaryngology Referral

Refer immediately if any of the following are present: 1, 2

• Asymmetric hearing loss (≥15 dB difference at 2+ frequencies between ears, or ≥15% difference in speech recognition scores)
• Conductive or mixed hearing loss suggesting:
  • Cerumen impaction
  • Middle ear effusion
  • Tympanic membrane perforation
  • Cholesteatoma
  • Otosclerosis
• Poor word recognition (monosyllabic word score ≤60%)
• Sudden onset (within 72 hours—this is an otologic emergency)

Expected Pattern in ARHL

Age-related hearing loss should be symmetric bilaterally. 1 Any deviation from this pattern requires further workup including MRI of internal auditory canals to exclude vestibular schwannoma or meningioma. 1

Management Framework

If Symmetric ARHL with Recruitment

• Patient and family education about the paradoxical nature of hearing loss with recruitment—difficulty hearing soft sounds while moderate sounds seem too loud 2
• Hearing amplification with compression technology specifically designed to manage recruitment
• Counseling about impact on communication, safety, function, cognition, and quality of life 1, 2

If Conductive Component Identified

All conductive hearing loss is potentially correctable and requires otolaryngology evaluation for medical or surgical intervention. 1 This includes simple cerumen removal to complex ossicular reconstruction.

Critical Pitfalls to Avoid

• Do not dismiss hyperacusis as purely psychological—it often reflects underlying auditory pathology requiring objective testing
• Do not assume bilateral symptoms mean symmetric hearing loss—formal audiometry is required to document symmetry
• Do not delay referral for sudden hearing loss—this is an emergency requiring steroids within 72 hours 1
• Do not order MRI without first documenting asymmetry on audiometry—this wastes resources and may not be indicated for symmetric ARHL

Immediate Next Step

Order formal audiologic evaluation before any other intervention. The audiogram will determine whether this patient has symmetric ARHL (manageable with amplification and counseling) versus atypical features requiring specialist referral. 1, 2
