Conclusion

Can You Keep That Noise Down?
Text Box: In conclusion, soundproofing is linked more to sound absorption rather than having a material that acts as a sound barrier, proving the first part of my hypothesis. The experiment showed that absorbent materials such as fiberglass insulation (R12) and the corrugated foam, no matter how thick or thin they are, have soundproofing abilities greater than a barrier of sound. Therefore, we can hypothesize that using absorptive materials like fiberglass insulation (R12) and corrugated foam will do a better job at soundproofing than using material that will act as barrier of sound such as wood and gyproc. Surprisingly, the sound level was higher in the 10” box compared to the 16” box, disproving my hypothesis. This may have been due to the control sound being a greater distance away from the sound meter in the 16” box than was the 10” box, as both control sounds were placed in the centre of each box. But the difference in sound level with each insulator was not a constant difference between the big box and the small box. This may be due to the insulators being different thicknesses. The insulator thicknesses ranged from 0.5” to 3.5”, making a different volume in each of the boxes. However, the differences in sound level between the two boxes were random, and did not follow a pattern with the volume of the boxes with the insulation. Fiberglass insulation, while being a temperature insulator is also a great material for soundproofing. At the store where they insulate the paint mixer with 0.5” acoustical tiles, it would be more effective to use fiberglass insulation (R12) as a sound insulator. This project will aid workplaces (See Appendix IV), construction firms, theatres and factories to utilize the most effective materials for soundproofing.
