  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?

Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

These Bricks Can Absorb Traffic Noise - Helmholtz Resonator

submitted by newtboy

11 months 2 weeks ago

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 Maker Meetup Club in Portland.
