The correct answer includes a comprehensive range of frequencies that are critical for assessing hearing ability and identifying potential hearing loss, particularly in occupational settings where noise exposure is a concern. By including frequencies from 500 to 8000 Hz, this option covers the primary speech frequencies and higher frequencies that are often affected by noise-induced hearing loss.

The rationale behind this wide range of frequencies is that human speech primarily falls within the range of 500 to 4000 Hz, and many acoustic signals related to daily communication occur within these frequencies. Additionally, focusing on frequencies like 3000, 6000, and 8000 Hz allows for the detection of specific types of hearing loss that may not be captured by more limited ranges.

Including a variety of frequencies is paramount for establishing a baseline hearing assessment and for monitoring changes over time, thereby allowing for the implementation of appropriate hearing conservation measures when necessary.

Consequently, this extensive range enables a thorough evaluation of an individual’s auditory capabilities, which is essential in ensuring workplace safety and health compliance.
