FAQs

Noise is any unwanted sound that is measured on a decibel (dB) scale. Any loud noise exposure at work or during recreation can impact hearing health.

Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears. Here are the decibels of some familiar sounds:

  • Whisper = 30 dB
  • Hand Drill = 98 dB
  • Jet Engine = 140 dB

How loud something sounds to you is not the same as the actual intensity of that sound. Sound intensity is the amount of sound energy in a confined space. It is measured in decibels (dB). The decibel scale is logarithmic, which means that loudness is not directly proportional to sound intensity. Instead, the intensity of a sound grows very fast. This means that a sound at 20 dB is 10 times more intense than a sound at 10 dB. Also, the intensity of a sound at 100 dB is one billion times more powerful compared to a sound at 10 dB. (CDC)
