This certainly falls into the "Gee, I never thought of that!" category.
Very interesting. Much more socially and environmenatlly friendly than tire deflation strips to reduce traffic noise.
Thanks for sharing.
Absorbing traffic noise with Helmholtz resonators (video)
Interesting talk.
@mahgister will like!
"These Bricks Can Absorb Traffic Noise - Thesis Presentation on Helmholtz Resonators"
"I gave a talk on my Masters Thesis Project in Architecture focusing on Altering Soundscapes in Exterior Environments using Helmholtz Resonators in Ceramic Bricks to absorb Low Frequency Traffic Noise.
I recently graduated from @BartlettArchUCL at University College London and was invited to give a talk on my project for the Portland Digital Fabrication Club in Portland."
