Decibels Quiz – Answers


       

Here are the answers to last week’s quiz on decibel levels. Did you know which of these did/did not exceed the safety threshold of 85 dB? 

Quiz

  1. Jet airplane engine – Exceeds – 140 dB
  2. Refrigerator – Doesn’t exceed – 50 dB
  3. City traffic – Meets – 85 dB
  4. Vacuum cleaner – Doesn’t exceed – 75 dB
  5. .22 LR rifle – Exceeds – 134 dB
  6. Fireworks – Exceeds – 145 dB
  7. Crowded restaurant – Doesn’t exceed – 70 dB
  8. Rock concert – Exceeds – 115+ dB
  9. Steady rain – Doesn’t exceed – 50 dB
  10. Washing machine – Doesn’t exceed – 75 dB

Remember, when you know you’re going to be around loud noises, always wear hearing protection, especially when you expect that exposure to exceed an hour or more. The minor inconvenience is temporary — noise-induced hearing loss (NIHL) and tinnitus are forever.
