What is the human hearing range for equipment noise?

10 - 15,000 Hz
100 - 10,000 Hz
20 - 20,000 Hz
50 - 15,500 Hz

The correct answer is: 20 - 20,000 Hz

The human hearing range for equipment noise is generally considered to span from 20 Hz to 20,000 Hz (or 20 kHz), which is why the choice indicating this range is correct. This range reflects the frequencies that a typical human ear can perceive, starting from the lower frequencies of deep bass sounds up to the higher frequencies of treble sounds. Understanding this range is essential in contexts such as maintenance and reliability because equipment noise can often fall within this spectrum. Being familiar with the human hearing range is important for evaluating noise levels, ensuring compliance with occupational safety standards, and minimizing potential hearing damage among workers. The other options listed provide narrower frequency ranges, which do not encompass the entire spectrum of human hearing. Since effective communication regarding equipment noise regulations and potential impacts on human hearing relies on this full range, it's vital to be aware of the correct limits.
