What type of sound intensity level corresponds with normal conversation?

Normal conversation typically occurs within a sound intensity level of around 60 decibels. This level is consistent with the average volume at which people speak in everyday settings, allowing for clear communication without raising one’s voice unnecessarily.

Understanding decibel levels is crucial for electricians and other professionals who work in environments with varying noise levels. A 60 dB sound level is comfortable for conversations and indicates an environment where speech can be easily heard and understood without straining.

The other options present sound intensity levels that are either lower or significantly higher than what is typical for normal conversation, which may lead to discomfort or strain in communication. For instance, levels below 60 dB may not be sufficient for audible speech in noisy settings, while levels above could contribute to a more disruptive or stressful atmosphere.
