Dude invented wasp houses.

Is there a follow up on this in application on site? Perhaps an A / B comparison on the overall impact in a given environment could really cool. This being seen in application in real life could be very powerful. Very cool idea!!

Good job. However the focus should be to reduce the number of cars on the road, first and foremost. You should always go to the source of the problem and ask if there are better ways of transportation, like public transportation, walking and biking.

what is the "Sheffield foam" ?

My design for highway sound barriers incorporates three major functions: to lower traffic noise, to find a use for fly-ash from coal burning and to enhance environmental factors. The structural strength derives from open cell bee-hive pattern constructed in panels capable of interlocking vertical structures forming a zig - zag to enhance stability and absorb wind load. The forms would utilize Fiber-reinforced polymer (FRP) instead of steel rebar for enhanced structural stability and longevity. The use of fly-ash in the cement instead of sand would alleviate proliferation of a troublesome environmental pollution problem. Each cell of the pattern would be large enough to encourage bird nesting. The bird nests would provide sound absorption material.

Thanks but no need for those bricks, soon all cars and trucks will run on batteries , noiseless🎉

Extrude a hollow tube and then form a hole and slap a roof on it

Is the 10 db to 8% increase in heart disease related more to it being correlated with being in a city in general.

the bambu lab A1 combo 3d printer, can print with 4 colors. i will try to print familys pet with the printer, in colors.

wait I thought you'd put a qr code to this actual video lol

Have you considered the production method known as centrifugal casting? It is often used in metallurgy and complex plastic shapes for casting, as it eliminates bubbles and ensures uniform thickness. The only thing left to work on is how it will function with your product's shape. It was very interesting to hear about your design process and final product; it is a very clever solution.

It is great to see research money being spent where grads take so many other issues into account. "Build it and be damned" was a vanity which led to so many towns and cities suffering from unanticipated phenomena such as highly localized whirlwinds, concentration of reflections melting parts of cars (London) and the sonic funneling of so many built areas with very high and semi high buildings. You mention London parks but do not confirm that background noise of streets is very much reduced or loses rumble in most of them, even quite small ones. In contrast, the parks of New York tend to retain rumble over longer distances from the perimeters and there is quite a long reach of city surface sounds there. The city of Sheffield's parks have the New York problem except those abutting the rising strata towards the Peak District. The reasons are due to what the cities are built on and London is built on clay and shale. Now, take the persistence of low frequencies in the other cities and we can work out why city noise reaches further (given that all pitches and frequencies of sounds have sub-sonic harmonics. Cities on rock have street noise bouncing between buildings and funneling too but in London you can measure the same sort of bounce in streets yet parks are significantly quieter. The bounce and spring effect is important in the work of Helmholtz and his famous resonators are in fact springs themselves. He reasoned that sonic pressure is indifferent to air pressure and changes in 'packets' of waves. In his day there were no heavy motorized vehicles not on rails generating the low frequency basis for higher frequency low harmonics to adhere to. Street sounds would mostly be asynchronous horse shoes on cobbles and steel rims on carts etc. The good news is that sonic energy can be transduced into useful forms of energy (including electrical current) and this could have a reduction effect in such as streets, albeit not at subsonic levels. The bad news part is that your bricks would be unlikely to reduce medium low and low frequencies at the site but could conceivably slightly reduce mid-high frequencies. Their longevity would be slight if not glazed and polished and kept clean beyond thin algae and the right types of moss -- which themselves are sound and chemical pollutant absorbers as well as carbon chains. Fauna habitat sounds worthy but brings dirt and therefore neck blockage. Bird droppings alone are corrosive and destroy the glazing, allowing moisture ingress and expansion below -- 1C. On the other hand, materials scientists and civil engineers could build with or coat buildings with moss conducive materials for general, natural air filtering and the dampening of at least some sounds in busy streets but not more than just about measurably on the site in question. Finally, in studies of noise in cities, London's poor showing could be improved by removing all pure jet aviation from a high percentage of Greater London's airspace with exceptions for very quiet turbo-prob aircraft. Were the incoming government to pass this into law a clause would exclude turbo-prob planes not using 95%+ green fuel. Such aircraft could be used on an automated shuttle basis, thus allowing expansion of the UK aviation industry all over the realm and the large airports too proximate to densely inhabited areas diminishing or being re-purposed.

Cool. I’m an amateur painter and future arts and craft teacher, in other terms I think this prototype can be translated for creating natural lightscape in cities! Too bad you don’t always get the sun when buildings are blocking the pathway.. Best regards Julie Marie Abrahamsen. Let me know if you liked the idea. I think you know what material you should use, obviously 😊

Living next to a busy road and about to build a new garden wall these would be fantastic if they took some road noise off the property wall. Look very rodent friendly also

you know what else these bricks can absorb? water. what does water do in the winter time? what happens when water freezes? it expands... if you want to see for yourself why these bricks are not a good idea, fill a glass with water and put it in the freezer overnight. just make sure it's a glass you don't want anymore.

Bird, insect, snake and rat : its free real estate !!

"Architects may design a structure without considering acoustic issues" NO FUCKING KIDDING. See: every goddamned library Local politicians, donors, university presidents, school superintendents, all just LOOOOVE a flashy looking library as a campus/community centerpiece, and they love going for all kinds of wacky designs to make it distinctive. They love smooth, shiny surfaces, and they love curves. And what are the worst surfaces for making a space quiet? I've seen a school library in the shape of a wankel rotor with glass walls. I've seen one with concrete walls forming two opposing parabolas. At least the wankel rotor one had some of that afterthought sound deadening. The parabolic one had a hardwood ceiling. Only carpet on the floor did anything to quiet it. My favorite though is the reference room at the Chinese national library in Beijing. At least it's rectilinear. But it's a gigantic open void, with glass and hard surfaces all around. The only thing breaking up the vast echoes is the book shelves.

Hi from Portland, Oregon!!

Just like a nordic engineer doin' churches half a century ago, I love Helmholtz

I am sorry for being that person, but wouldn't laying regular bricks in a 3d pattern, similar to sound dampening panel, work just good enough while being 50 times simpler? Or maybe plaster upcycled glass bottles and jars and ceramic pots into the brick wall. This seems over-complicated, I am skeptical.

Bonk, those resonators will be filled with animal nests

He worked for Barclays and doesn't know how to pronounce if properly?🤣🤣

And then 99,99% of humans believe they deserve everything when it's those few people who actually make the world better. Aliens will visit just to get dem bricks!

great thing. the only bad thing i see is the holes "for insets ad birds", u missed rats too. I will a sure u, a wall with that many holes will make the dirtes street ever. In my zone, no 1 can sit on street benches cuz its all pooped, and theres only trees...

These are used in Puerto Rico

Very very cool Mr Pub 👍

thats cool but if anyone whos feeling slightly rambunctios be it a kid with a bat or a drunk collage student all those poking out tubes are getting destroyed 100% as a game to see who can smash the most or just for fun.

I I I I to much self esteem.

Nice project. Thank you

In Texas these will end up housing yellowjackets and mosquitoes

Then they fill with water and rot, Animals next inside your walls. So many problems with it.

Ciao video bellissimo!! can I ask a question, what about adding small amounts of water in the hollow bricks? could also help boost the plants and biodiversity.

The easiest way to use this, which I saw in a radio concert hall, is lining a wall with traditional red bricks turned to their side. The brick holes become sound trapping "pipes", and whatever you say magically disappears into the wall. It was surprisingly effective given the minimal manufacturing cost (compared to any specialised shape).

We have so many incredible minds making fantasist strides in eco related things of all kinds that we need to survive yet we are not implementing them. Why? Money for the few, lots and lots of money made by us for them. Until we're dying it won't change on it's own. Vote for the environment.

who made the drawing of the vitruvian man? .... yeah, thought so ...

How good is plastic as sound absorber? There is already abundance of that everywhere, and with plastic extruders it could be used easier to make overlay puzzles in public places.

Dont understand english, but we need this material... Woow

What happens when rain is inevitably blown into the cavities?

Will it still work if you put something that keeps birds out?

If we eliminated road noise think of how much better life would be.

Those are some phony legos for sure.

What happens when they get filled with ice and crumble onto the roadway?

If it was a bong it would creative as well as useful.

This is actually useful research. Academics tend to think in abstract terms, but discovering the process for fabricating these shapes in clay seems like a discovery in itself.

Brilliant! Your conclusion brought it back to the design fundamentals. I’m thinking I missed the purpose of the ceramics limitation. One would think modern materials know how would help scale the manufacturing. The impact and simplicity are impressive.

Cool, but trees and shrubs work great too.

I wonder if these resonators could be integrated into the structure of cars to reduce noise at the source? Specifically I am thinking that the wheel wells could have two walls with the resonant spaces in between them to absorb the tire noise that seems to be the majority of automobile sound.

As a Czech native I can confirm that krčma means tavern :D
