Validation of self-reported hearing loss using television volume

Area of Science:

• Audiology
• Otolaryngology
• Primary Care Medicine

Background:

• Hearing loss is a common condition affecting millions worldwide.
• Early detection of hearing loss is crucial for effective management and intervention.
• Traditional diagnostic methods like pure tone audiometry require specialized equipment and personnel.

Purpose of the Study:

• To evaluate the diagnostic accuracy of television volume as a screening tool for hearing loss.
• To determine the sensitivity, specificity, and predictive values of increased television volume in identifying hearing impairment.

Main Methods:

• A prospective study involving 117 patients undergoing pure tone audiometry for the first time.
• Data collected via a self-administered questionnaire assessing television viewing habits and volume.
• Analysis of sensitivity, specificity, diagnostic accuracy, and predictive values.

Main Results:

• Patients reporting increased television volume had a 68% likelihood of hearing loss of 25 dB or more, with a mean loss of 35 dB.
• Increased television volume demonstrated a sensitivity of 81% and a specificity of 52% for detecting hearing loss.
• Watching news programs at increased volume was associated with a mean hearing loss of 41 dB, showing 75% sensitivity and 71% specificity.

Conclusions:

• Television volume serves as a practical and accessible marker for hearing loss, particularly in primary care settings where audiometry may not be readily available.
• While useful for initial screening, the test's specificity is limited, necessitating further audiological evaluation for definitive diagnosis.
