Free Noise Related Downloads from Aearo

After providing us with audio files (See Wednesday’s Post) and video files (See yesterday’s blog), Aearo is also making available free a large selection of downloadable documents relating to noise hazards, hearing protection and sound measurements.

Especially fun (possibly a great document to post on the bulletin board) is the Noise Thermometer. Additionally, the Noise Navigator Database logs over 1700 noises.
