  1. Comparative Ability of Exterior Imported Hardwood Plywood, Gypsum Board, and Expanded Polystyrene to insulate a Wooden Box Against Sound Sheridan Drodge Undergraduate Tennessee Technological University

  2. Project Summary • Problem: How do the soundproofing abilities of exterior imported hardwood plywood, gypsum board, and expanded polystyrene compare? • My objective is to perform an experiment that will effectively test and compare the ability of exterior imported hardwood plywood, gypsum board, and expanded polystyrene to insulate a plywood box against sound.

  3. Experiment • Box Structure • Door • Sound Source • Sound measurement outside box (zeroing) • Sound Measurement of box alone • Attaching Materials/Unattaching Materials • Sound Measurement with Materials • Comparison

  4. Introduction or Background • Problem: How do the soundproofing abilities of exterior imported hardwood plywood, gypsum board, and expanded polystyrene compare?

  5. Literature Sources • … Polymeric Systems for Absorbing Airborne Sound • …Second Order Sound Phenomena … Sound Waves • Sound Absortion … Multi-layered Constructions … Powdered Layers and Porous Sheets • …Acoustic & EM Wave Absorber … ResistiveFilms and Glass Wool • Studies of Polymeric Systems … Damping Vibrations Sonic Range • Sound Transmission Properties

  6. Objective/Hypothesis Statement Hypothesis: There is a difference in the ability of exterior imported hardwood plywood, gypsum board, and expanded polystyrene to insulate to insulate a plywood box against sound. Objective: My objective is to test the ability of exterior imported hardwood plywood, gypsum board, and expanded polystyrene to insulate a plywood box against sound.
