The acoustic properties of a room have a surprising impact when you want to use a microphone. [RayP24]’s son was trying to make his bedroom into a better recording studio, and for [Ray], that turned into an artfully-executed wall panel project. Fortunately, the process is documented so we all can learn from it. When it comes to acoustics, you can often get a whole lot of improvement from surprisingly few changes. And, as this project demonstrates, you can make it look like a decorative piece to boot.
When arranged and placed on the wall, these panels look like an art piece, a decoration you could get from a somewhat fancy store. If you show them to someone, they might not believe that they also serve as a functioning home acoustics improvement, dampening the sound quite well for audio recording needs. The panels are built out of individual circles, cut out in a way that uses as much of a 3/16″ (5mm) plywood sheet as possible, with hollow circles serving as frames to attach foam-backed fabric. In the Instructables post, [Ray] talks quite a bit about how you can assemble your own and what liberties you can take. There’s also a short video accompanying this project, which you can see after the break. This project is begging to be recreated.
There’s a sizeable amount of hacking-meets-home improvement-meets-home acoustics projects out there, especially lately, when so many people are stuck at home for one reason or another. Just a few months ago, we covered another marvelous “art piece turned reverb killer” project operating by a slightly different principle, and also going a bit more into the theory. Perhaps in a few years, we will no longer have to build panels or structures for our soundproofing needs, as purpose-grown mycelium shapes will do that for us. And once it becomes a question of where to hang your newly-built acoustic panels, this simple guide is a good place to start.

Ding dong, the office is dead — at least we hope it is. We miss some of the people, the popcorn machine, and the printer most of all, but we say good riddance to the collective noise. Thankfully, we never had to suffer in an open office.
For many of us, yours truly included, home has become the place where we spend approximately 95% of our time. Home is now an all-purpose space for work, play, and everything in between, like anxiety-induced online shopping. But unless you live alone in a secluded area and/or a concrete bunker, there are plenty of sound-based distractions all day and night that emanate from both inside and outside the house. Headphones are a decent solution, but wearing them isn’t always practical and gets old after a while. Wouldn’t it be nice to be able to print your own customized sound absorbers and stick them on the walls? Continue reading “There’s A Fungus Among Us That Absorbs Sound And Does Much More”
Looks like [Dino] is getting the band back together. After a junkyard tube amp and a DIY tremolo stompbox, he’s back again, this time doing a bit of sound treatment in his studio.
Most rooms naturally have a bit of flutter echo. You’ll notice this when you move into an apartment or new house – rooms sound a lot more cavernous without rugs, drapes and furniture. Unfortunately, having a bunch of couches doesn’t bode well for the workflow in a studio despite what MTV Cribs may have told us. The usual solution is to put up some sound-absorbing material on the walls, and a metric ton of cardboard egg cartons don’t work.
[Dino] found a bunch of acoustic panels his neighbor threw out during a renovation (yes, we know, he’s very lucky). After doing some pre-installation tests, the panels were hung. Afterwards, the amount of echo was drastically reduced.
The good news is we finally get a look inside [Dino]’s studio. We saw the junkyard tube amp we covered earlier, but not the neat tremolo pedal he made.
Check out [Dino]’s video of sound treating a room after the break.

[Eric Wolfram] wrote in to let us know about a simple and cheap acoustic panel DIY he put together. When installing a home theater acoustics are often neglected (especially if you spend so much on the TV you cannot afford any furniture for the room) resulting in reduced listening quality and poor spacial sound imaging from your surround system (also responsible for the furniture problem). The addition of sound absorbing panels helps control the acoustics of the room and may even class up the place a bit. These are also come in handy for home studio usage where a low level of reverberation is preferred.
The panels are relatively simple to produce on a budget, just a sheet of 2″ thick dense fiberglass board glued into a wooden frame and covered in a sound-transparent fabric. [Eric] goes into a lot of the material selection process to help you along your way. The best part about the project (aside from its obvious utility) is that all of the materials can be found cheaply at your average home improvement store, with the exception of the fabric. [Eric] mentions that you can substitute colored burlap if need be. Once the panel is assembled and glued it just has to be hung on the wall of your choice like a large heavy picture frame. This could certainly help the acoustics and reduce some slap-back echo in your warehouse/shop. We might have to try this one over the weekend.
As with many of the projects covered on hackaday, [bongodrummer]’s Dust Sniper came about because of a lack of effective commercial solutions, in this case to the problem of quiet dust extraction.
Workshops are generally full of dust and noise, both of which take their toll on the human body. This is why safety regulations exist for noisy and dusty workplaces and–as [bongodrummer] rightly points out–we have to take precautions in our own home and community workshops. Hearing protectors, dust masks and safety goggles are integral, but reducing the amount of dust and noise in the fist place is paramount.
Using mostly scavenged materials [bongodrummer] did a quality job building the Dust Sniper–and all for a bill of materials totaling £20. It has an integrated work surface, automatic switches on 2 vacuum lines to sync up with power tools, a cyclonic air filter that prevents clogging the HEPA filter and reducing suction power, inlet and outlet soundproofing, and a plain old power outlet for good measure.
Whether or not you’re interested in building an integrated workbench/extractor system like this one, we recommend you check out the details of the cyclone filter and the sound reducing components. Not only are they an interesting read, but they could be useful to apply in other projects, for example a soldering station with fume hood.
We think it would be really neat to include more cyclones in our projects. Stick around after the break to see [bongodrummer]’s prototype cyclone filter in action.
