## Step 1The problem is asking us to identify the correct measurement unit that can be used to determine if earplugs are needed when working in a factory. The options provided are watts, amps, decibels, and delta waves.## Step 2We need to understand what each of these units measures. Watts and amps are units of power and current respectively, and delta waves are a type of brain wave. None of these are related to sound measurement.## Step 3Decibels, on the other hand, are a unit of sound intensity. They are used to measure the loudness of sounds. The decibel scale is logarithmic, which means that each increase in 10 decibels represents a tenfold increase in sound intensity.## Step 4In the context of a factory, where noise levels can be high, it is important to measure the sound intensity to ensure that it does not exceed safe levels. Therefore, decibels are the correct measurement unit to use in this situation.
