Hearing Protection: Measuring Sound. Loudness is measured in decibels (dB). As decibels rise, loudness quickly increases. A 10-dB rise is a 10-time leap in loudness. That means an 80-dB sound (a vacuum cleaner) is 10 times louder than a 70-dB sound (a telephone ringing). And it's100 times louder than a 60-dB sound (normal conversation).One of my favorite breakfasts is the Egg McMuffin from McDonald’s, but not having an automobile means I have to order them from UberEats, and nothing makes me feel like more of a d...Exposure Time Guidelines.
