Sound Graph
This was the information we got when we turned the machines on in the engineering design room. We used the dust collector, miter saw, and the table saw to see what was within the safe hearing levels.
Human safety hearing levels
According to this chart the only tool that's safe for more then 15 minutes is the table saw. Which can be heard for more then 8 hours without hurting your ears. While the others are above 100 dB they will hurt your ears if you stay near them for any longer then 15 minutes.
Sound test Program
This is the program used for the sound test. Its very similar to the light tests program and used for the same purpose, to find differences in the sound.
