  • Turn down the volume two notches on your radios and personal stereo systems with headphones.
  • Turn down the volume one notch on your television.
  • Do NOT honk your horn, except in the case of imminent danger.
  • Do NOT tip cab drivers who honk their horns illegally.
  • Avoid noisy sports events, restaurants, rock concerts and nightclubs unless you use hearing protection.
  • Replace noisy activities with quiet ones such as taking a walk, visits to libraries and museums.
  • Ask your health club instructor to lower the music.
  • Ask the movie theater manager to turn down the volume.
  • Wear adequate hearing protection if you must be in a noisy environment (the subway, mowing the lawn)
  • Turn off the television during dinner and have a quiet conversation instead.
  • Get a free hearing screening.
  • Attend a town meeting to review (or develop) a local, enforceable noise ordinance.
  • Spread the word about the danger of noise,

And remember… observe one minute of no noise from 2:15 – 2:16 pm (regardless of location/time zone).

Noise Awareness Lesson Plans

These lessons can be used for most grades to learn about measuring sound and hearing anatomy.

Sound Measures – Students use a sound level meter to measure, compare and graph sound levels in different environments.

Your Ear – Students explore how the ear hears and work through an interactive demonstration.

How Loud is Too Loud? – Students create a wheel that will show them various sound sources, the decibels , and allowable exposure time.

Loud Sounds Bookmarks – Students familiarize themselves with the idea that some sounds can be too loud.

Kids’ Noise Awareness Activities

These are all activities families can do at home and still have fun learning about sound and hearing.
