What symptom is likely caused by exposure to high frequency noise in the workplace?

Exposure to high-frequency noise in the workplace is associated with hearing loss due to the potentially damaging effects such sounds can have on the auditory system. High-frequency sounds can be particularly harmful because they may not be as readily perceptible or noticeable, leading to prolonged exposure that silently affects hearing capabilities. The structures within the ear, especially the hair cells in the cochlea that are responsible for detecting sound, can become damaged over time when subjected to intense noise levels. This damage can result in temporary or permanent hearing loss.

In contrast, improved focus and increased productivity are typically not linked to high-frequency noise exposure; rather, these positive outcomes are generally associated with a quieter and more controlled work environment. Similarly, while fatigue can be caused by various factors, it is not a direct or primary symptom of exposure to high-frequency noise, which specifically targets hearing and may lead to an adverse auditory health outcome. Thus, hearing loss stands out as the most relevant and impactful symptom resulting from such exposure.
