Recommended Audiological Test Battery Following Combat Noise Exposure: A Clinical Approach.

Area of Science:

• Audiology
• Military Medicine
• Hearing Science

Background:

• Combat noise exposure presents unique challenges for audiological assessment.
• Current evaluation methods may not adequately address combat-related hearing injuries.
• A standardized protocol is needed for consistent and effective hearing evaluations.

Purpose of the Study:

• To establish a standardized, evidence-based audiological protocol for evaluating combat-exposed personnel and civilians.
• To address the gap in assessment approaches for combat-related hearing injuries.
• To emphasize early detection, detailed assessment, and practical clinical implementation.

Main Methods:

• Developed a comprehensive audiological assessment framework for combat noise exposure.
• Integrated specialized forms for exposure history, conventional and extended high-frequency audiometry, otoacoustic emissions, immittance testing, and auditory evoked potentials.
• Included interpretation criteria accounting for blast effects, traumatic brain injury, and psychological trauma.

Main Results:

• The protocol enables auditory dysfunction detection even with normal standard audiometric results.
• Facilitates more accurate assessment of combat-related hearing impairment.
• Supports early detection of hearing changes following combat noise exposure.

Conclusions:

• This protocol advances clinical practice for evaluating combat noise-induced auditory dysfunction.
• The integrated test battery and interpretation guidelines enhance detection and monitoring.
• Further validation studies are required to establish effectiveness in military and clinical settings.
