Unsupervised audiometry in non-sound-treated rooms is feasible, provided noise levels meet standards. Circumaural headphones and potentially online noise monitoring are key for accessible hearing tests.

Area of Science:

  • Audiology
  • Acoustics
  • Biomedical Engineering

Background:

  • Hearing loss is a global health issue with limited access to professional care.
  • Developing accessible, unsupervised audiometric testing is crucial for widespread hearing healthcare.
  • Investigating alternative testing environments addresses accessibility barriers.

Purpose of the Study:

  • To assess the acoustic viability of inexpensive, non-sound-treated rooms for unsupervised audiometric testing.
  • To compare ambient noise levels in these rooms against established audiology standards.
  • To determine the feasibility of user-operated audiometry outside traditional sound-treated booths.

Main Methods:

  • Ambient noise measurements (10 min) were conducted in 20 non-sound-treated rooms (libraries, clinics).

  • Noise data were compared against ISO 8231-1 Maximum Permissible Ambient (MPA) noise levels.
  • The acoustic attenuation provided by DD450 circumaural headphones was factored into the analysis.

    • Main Results:

    • Most non-sound-treated rooms met MPA levels, with violations primarily from transient sounds.
    • Ambient noise in non-sound-treated rooms showed greater fluctuations than in sound-treated rooms.
    • Noise violations predominantly occurred at low to mid-low frequencies.

    Conclusions:

    • User-operated audiometry in non-sound-treated rooms is possible under specific conditions.
    • Circumaural headphone attenuation is essential for maintaining acceptable noise levels.
    • Online systems for real-time noise assessment may enhance the reliability of unsupervised testing.
