Which frequencies are typically tested for occupational monitoring?

The correct answer highlights the frequencies that are commonly utilized in occupational hearing monitoring, which include 500, 1000, 2000, 3000, 4000, and 6000 Hz. These specific frequencies are chosen because they are crucial for assessing hearing sensitivity in environments where individuals may be exposed to hazardous noise levels.

Monitoring these frequencies is essential in occupational settings as they correlate with the frequency range of speech and significant sounds in everyday communication, thus providing insight into how noise exposure can affect overall hearing health. Additionally, 4000 Hz is notably critical as it is often at this frequency where noise-induced hearing loss begins to manifest, making it vital for early detection.

The selection of these frequencies allows for a comprehensive understanding of an individual's hearing profile in relation to their work environment, facilitating proper interventions or protective measures as necessary to prevent further hearing deterioration.
