Project Type: Co-op
Duration: September-November 2020
Skills Used: SolidWorks, Hand Fabrication, Vendor Interaction
Description: Small noise isolating chamber used to record cordless vacuum sounds. Used during COVID-19 pandemic to not only share noise files digitally but to analyze acoustic changes across products.
Diagram of inner parts of chamber.
Challenges:
- Keep costs low compared to anechoic chambers on the market while maintaining best performance
- Allow range of products to be tested inside using controlled parameters
- Gather data and observations to be shared to remote employees
Solutions:
- Research led to use of MDF and noise-isolating foam in construction
- Interchangeable floor and pass-through for various wand and nozzle combinations
- WiFi camera and USB microphone pass-through to record data and video
Results:
- Reduced initial proposal cost from ~$3000 to ~$600 with still useable performance
- Designed to be able to roll on rubber casters and fit through standard door frame
- Designed to be adaptable for different testing scenarios
