Abstract
This literature review investigates the application of wide dynamic range compression (WDRC) to enhance hearing protection and communication among workers in a noisy environment. Given the prevalence of noise-induced hearing loss, there is a major need to provide workers, with or at risk of hearing loss, with a solution that not only protects their hearing but also facilitates effective communication. WDRC, which amplifies softer sounds while limiting louder sounds, appears a promising approach. This review explores 46 articles investigating WDRC performance on speech intelligibility and loudness perception in noise for individuals with normal hearing or mild to moderate hearing loss. The findings illustrate a complex interplay between several factors such as WDRC parameters, noise types and personal factors. Although WDRC holds promise for enhancing auditory protection and communication in noisy work settings, targeted research towards customizable and adaptive WDRC configurations is crucial for optimizing its application across industrial noise environments.
