[FEDERAL CLINICAL RECOMMENDATIONS IN DIAGNOSIS, TREATMENT AND PREVENTION OF HEARING LOSS DUE TO NOISE]

Area of Science:

• Otolaryngology
• Audiology
• Occupational Health

Context:

• Noise-induced hearing loss (NIHL) is a progressive sensorineural hearing impairment.
• Occupational exposure to excessive noise levels is a primary cause.
• NIHL affects the auditory analyzer, leading to chronic bilateral hearing loss.

Purpose:

• To summarize the current understanding of noise-induced hearing loss.
• To highlight the lack of a definitive cure for sensorineural hearing loss.
• To recommend therapeutic strategies for managing NIHL.

Summary:

• Noise-induced hearing loss is a slow-onset impairment resulting from occupational noise exposure.
• It manifests as chronic, bilateral sensorineural hearing loss, indicating damage to the auditory system.
• Current management focuses on tailored treatments addressing pathogenic mechanisms and symptoms, alongside complication prevention.

Impact:

• Emphasizes the need for non-drug therapies to manage NIHL.
• Suggests interventions that enhance labyrinthine blood flow.
• Recommends therapies targeting tissue and cellular metabolism for hearing loss management.
