Explanation:

Decibels (\(dB\)) are the unit used to measure sound intensity. When the sound level (measured in decibels) in a factory exceeds a certain threshold (e.g., 85 dB over an 8 - hour period), earplugs are typically recommended to protect hearing.

• Watts (\(W\)) is a unit of power.
• Amps (\(A\)) is a unit of electric current.
• Delta waves are a type of brain wave.
