Final answer:
Both in the ear canal style and over the ear style ear protection methods will work for moderately loud noise.
Step-by-step explanation:
If a noise is not excessively loud, either in the ear or over the ear style ear protection methods will work. In the ear canal style ear protection is a good option because it fits directly into the ear canal, blocking out noise. Over the ear style ear protection, like earmuffs, covers the entire outer ear and provides a barrier against noise. Both options can effectively reduce the volume of noise and protect your ears.
