From the Guidelines

Sudden auditory sensitivity after cerumen removal is typically a temporary condition resulting from the brain's adjustment to newfound sound levels, and it usually resolves on its own within a few days. This phenomenon occurs because the removal of impacted ear wax allows sound waves to reach the eardrum more directly, making sounds seem louder than before 1. The auditory system, having adapted to reduced sound input due to the blockage, needs time to recalibrate to normal sound levels. To manage discomfort during this adjustment period, it is recommended to avoid loud environments when possible, use earplugs in noisy settings, and keep volumes lower on devices.

Key considerations for managing sudden auditory sensitivity include:

  • Avoiding loud noises to ease the adjustment process
  • Using ear protection in environments that are potentially too loud
  • Adjusting volumes on personal devices to comfortable levels
  • Monitoring the condition to ensure it does not persist or worsen

If the sensitivity persists beyond 1-2 weeks, becomes painful, or is accompanied by other symptoms like dizziness, tinnitus, or discharge, it is crucial to consult a healthcare provider, as these could indicate an underlying issue such as an ear infection, eardrum damage, or a more complex auditory processing problem 1. The guidance provided in the clinical practice guideline for earwax (cerumen impaction) emphasizes the importance of proper ear care and the risks associated with improper removal techniques, highlighting the need for professional evaluation and treatment when symptoms persist or worsen 1.

From the Research

Causes of Sudden Auditory Sensitivity after Cerumen Removal

  • Sudden auditory sensitivity after cerumen removal can be caused by various factors, including the method of removal and the individual's ear canal condition 2, 3.
  • The microsuction procedure, a common method for removing impacted cerumen, can cause a temporary threshold shift (TTS) of hearing, which may lead to auditory sensitivity 3.
  • The TTS caused by microsuction can range from 0 to 16.2 dB, with the highest TTS at 6 kHz, and can occur in up to 86% of ears 3.
  • Other methods of ear wax removal, such as syringing, can also cause complications, including perforation of the tympanic membrane, which may lead to auditory sensitivity 4, 2.
  • The use of cotton tip applicators to clean the ears can push ear wax further into the ear canal, causing impaction and potentially leading to auditory sensitivity after removal 5, 6.

Factors Contributing to Auditory Sensitivity

  • Pre-existing defects of the tympanic membrane can increase the risk of complications, including auditory sensitivity, after ear wax removal 2.
  • The skill level and training of the person performing the ear wax removal procedure can also impact the risk of complications and auditory sensitivity 4, 2.
  • The type of ear wax removal method used, such as syringing or microsuction, can also influence the risk of auditory sensitivity 2, 3.
