Sound Absorption Wall

New Review

What types of materials absorb sound? Learners explore sound waves, the decibel scale, and how different materials affect sound. Then, they use their knowledge of sound meters to complete a STEM engineering design task to build sound-absorbing walls. Finally, pupils evaluate each other's sound meters to determine which materials absorbed sound the best.
