I do not believe the school would allow woodshop equipment and tools that are unsafe to the human hearing system.
Our Robot (:
This is the robot that we used for this challenge. All we needed was the NXT programmer and sound sensor, which we attached to port 1 on the NXT. This sensor is to help colect the data we are testing relating to the sound of the equipment.
This is the program we used for this challenge. It shows that the sound sensor is connected to port 1 on our NXT programmer. The sound sesnor will collect data of the power of the noise (how loud it is) every second for 30 seconds.
This is the data we collected for this challenge. The first five seconds shows us collecting data near the dust collector system. On the graph a straight line is shown at the 100 decimals mark because the sound was higher than this value. The second machine we tested was the chop-saw, showing its peak at about 12 seconds. This machine reaches up to 100 decimals on our results. The last machine we tested was the jointer, shown between the 20-30 second mark. This machine was the quietest out of the three we tested, with the average sound being about 50n decimals. The peak right before it comes to 50 decimals could have been because we moved the sound sensor closer to the machine, then moved it away again.
This safety chart shows that the equipment being used in our school is unsafe to the human hearing system. The dust collector system is unknown to the exact decimal, but we know it reaches over 100 decimals, which would most likely put it into the "painful" category. The chop-saw reaches 100 decimals which puts it into the "extremely loud" category. Lastly, the jointer used at pur school is about 50 decimals, reaching the "very loud" category. This shows that children are at risk with hearing while using these machines, which could possibly effect them in the future in permanent hearing loss.
Machines at our School
These are pictures of the equipment used in our school. The dust collector machine is shown on the left, chop-saw in the middle, and jointer on the right. These are shown in th order as they are described above and collected on the data. They are also shown from the loudest to quietest machines.
