'My Science Fair Project Essay\r'

'My scientific discipline fair bulge out is about the sound infection through incompatible veneers. A veneer is the outer(prenominal) part of the house. It can withal be c all in alled a siding. The veneers I utilize were brick, cement fiber, and vinyl radical. I used these because they were three very common veneers. I purpose if I used common veneers it would work on the project mean more because people can checker sound transmission through common sidings. The trend I built the cement fiber and vinyl siding niche seates was, I cut ply wood sides. later I cut the sides I nailed them together to make a misfortune. After I made the box I wrapped the houses in house wrap. foretoken wrap is used as a moisture barrier. My purpose for the house wrap is not to distributor point water from coming in, but, I used it because approximately houses use it. After I wrapped the houses I nailed the siding on. I then used wood putty to fill the holes.\r\nThe brick box was a diffe rent procedure. After I wrapped the brick box I had to build a platform then I had to lay the brick with mortar. I had to attach the brick to the plywood with the fence in ties. I tested my buildings by putting a transistor radio into the plywood box. After I put it in the box I rancid it on at a low level, I then put the lid on the box and I used my sound level clock time. This meter measures the amount of atomic number 105s coming out of the house. A decibel is a unit of measurement for sound. I also did the same thing on a rubbishy and a medium sound level. I did this with all of the boxes. The brick box produced an medium of 10.33 decibels at a (80) 43 decibel volume, an average of 13 decibels at a (90) 53 decibel volume, and an average of 19.66 at a (100) 63 decibel volume with a extreme average of 14.33 decibels.\r\nThe cement fiber box produced an average of 19 decibels at a (80) 43 decibel volume, an average of 22 decibels at a (90) 53 decibel volume and an average of 30 decibels at a (100) 63 decibel volume. The Vinyl box produced an average of 27 decibels at a (80) 43 decibel volume, an average of 26.66 decibels at a (90) 53 decibel volume and an average of 33 decibels in a (100) decibel volume. My results of my project proved my guess of brick producing the least amount of sound transmission.\r\n'
