Sound treating a studio

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.

Cheap Acoustic Panel DIY

[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.

Thanks [Eric]!

Quiet Dust Extractor from Scavenged Materials

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.
