Steps
- Build a duct section with the blower fan at one end and the sound sensor at the outlet.
- Measure baseline noise levels at several fan speeds.
- Line part of the duct with acoustic foam and measure again.
- Build and test a simple silencer design.
- Calculate the noise reduction for each setup.
- Chart attenuation results and document the project for your portfolio.
What to photograph for your portfolio
