Explanation:

In the context of hearing protection guidelines, a standard rule is that if you need to raise your voice for someone to hear you when they are 8 feet away, hearing protection should be used. This is a common occupational safety and health (related to fields like Engineering or Medicine and Health in Natural Science, but the knowledge here is about safety standards) fact.
