How long will it take to damage your hearing while riding a jet ski, pushing a lawn mower or attending a rock concert?
SHA colorfully answers those questions with the Noise Thermometer. This 8.5" x 11" glossy color print (sold in bundles of 100 copies) illustrates the noise levels of various recreational activities and the amount of exposure time in which hearing damage is likely to occur. Useful in teaching both kids and adults about the dangers of noise to hearing.
