DailyDirt: Cool Sound Effects

from the urls-we-dig-up dept

Non-linear properties for materials can create some really cool sound effects. We're not talking about the 'Wilhelm scream' here, but some interesting ways to make soundproof walls -- and super-secret submarines. Here are just a few examples of bending sound in some new ways. By the way, StumbleUpon can recommend some good Techdirt articles, too.

Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.

Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.

While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

–The Techdirt Team

    Did insects invent it first?

    If this acoustic cloak pans out, maybe we could look at insects and fish (the prey of bats and dolphins/porpoises) to see if they've evolved this kind of sonic camouflage.

      Beta,

      That's an interesting idea... natural metamaterials would be a pretty cool discovery.

    Interesting stuff!

    I love improvised gear (as I can't afford high end stuff, so this is really cool to me. Now if you'll excuse me I needs some fizzy drink! ;o)
