Central Auditory and Cognitive Processing Impairment in Adults with Normal Hearing Exposed to Industrial Noise and Leisure Noise
Abstract
Background and Aim: Noise can lead to temporary or permanent changes in the structure and function of the peripheral and central auditory systems when experienced at high sound pressure levels over time. This study aimed to examine the effects of industrial noise and leisure noise—specifically from Personal Listening Devices (PLDs)—on central auditory and cognitive processing in adults with normal hearing.
Methods: In this cross-sectional study, 136 males aged 20–40 were divided into three groups: 45 exposed to leisure noise from PLDs, 46 exposed to industrial noise (average [Leq]<90 dB (A)/ 8 hours), and 45 with no history of noise exposure (control group). All participants had normal audiograms. To evaluate central auditory processing, the Dichotic Digits Test (DDT), Duration Pattern Sequence Test (DPST), and Quick Speech-in-Noise Test (Q-SIN) were used. Cognitive abilities were assessed using the Ray Auditory Verbal Learning Test and the Semantic Stroop Test.
Results: The results showed that the industrial noise group performed significantly worse on all central auditory and cognitive tests—except reaction time—compared to both the PLD and control groups. The PLD group also showed impairments in speech-in-noise perception, short-term memory, and selective attention relative to the control group. Additionally, a negative correlation was found between noise exposure and speech-in-noise performance.
Conclusion: These findings suggest that both industrial and PLD-related leisure noise can impair central auditory and cognitive functions in individuals with normal hearing, highlighting the need for broader assessments in noise exposure monitoring.
