Let’s say you need some Sonora® Black scrim ceiling tiles for a home theater project, and you order a few extra – “just in case.” Now that the install is done (and you have a few left) you can do something with them… like making a cool absorber panel with lights!
Everyone will have a different vision, but the basic supplies are…
- Acoustic Absorber Material (ex. Sonora® Black Scrim Ceiling Tiles)
- Wood for frame
- Acoustically transparent material/fabric (This one uses a polyester fabric map)
- Material to enclose the back (fabric scrim)
- Wood to mount lighting (This is a 1″x 4″ with espresso stain)
- Lights (here are custom, black-pipe light fixtures, but use other lights if desired)
- Wiring (Wirenuts, electrical tape, lamp cord, etc.)
- Assorted screws, staples, hanging hardware, PPE and tools.
Note: This is not a detailed DIY, as everyone will have a different set of materials and project goals, but these will show the basic steps to create a panel like the one above…. Here we go!
Cut the wood and make a frame that will hold the acoustic material, and the fabric to enclose it. Make the frame big enough to hold the material, and still be covered by the fabric. Make the frame as rigid as possible. Predrill your holes and make it square. Make it tight enough to hold the acoustic material with friction, but without crushing it.
This design is an old map that was printed on a lightweight, polyester fabric banner material. This one is roughly 4′ x 6′ with extra material around the edge to wrap it around the back of the frame. It’s best to have your starting fabric oversize – the graphics sized to the frame, with a boarder wide enough to wrap to the back for fastening. (In this case we will simply staple it to the back of the frame.)
Lay out the material and attach it to the frame. Be careful when putting the frame on the material. Take care in lining up the graphic to the frame, and keep an eye out for wrinkles and folds.
Fastening doesn’t need to be perfect on the back, but you do want it to be secure. Trim up the excess material if needed, and then flip it around and see what it looks like.
You could just fill it with the material and hang it like this if you didn’t want the lights, but this project is going the extra mile! We will attach a board to the top of the frame and attach the lights to that. This board will support the lights as well as the the frame. The hanging straps and rings will be attached to this as well, so don’t select a board that is too thin or flimsy.
How you mount the lights to the board and run the wires will be different if you are using different fixtures. This was made with 5 custom, black-pipe fixtures, that are basically just a flange, two 90° elbows, some pipe, and a lamp fixture mounted in a 1 1/4″ pipe reducer/coupler. Wire was stranded lamp wire (black and white), and it was left long to assist routing the wiring inside the panel.
The flange on these lights had 3 screw holes. Some washers and wood screws were used to attach them to the frame. The remaining fixtures were then measured and mounted – paying close attention to keeping consistent spacing and orientation of the lamps.
Note: This will vary depending on the type and number of lamps you use.
Now that we have all the fixtures mounted, let’s finish the wiring and put in the material!
(WARNING: If you are not comfortable with wiring – this is the point where you call in a friend, electrician, Wikipedia, or whatever other resource you use to make sure you don’t electrocute yourself, burn down the house, etc. Acoustics First assumes no responsibility for your DIY projects – but we wish you good luck!)
This wiring was all attached to a lamp cord that had a pre-molded plug, and readily recognizable hot (black) and neutral (white) wires. This entire fixture is being controlled by a smart outlet (“Alexa… Turn on the Awesome World Map.”), but could just as easily be hard wired to a junction box, or wired with an inline switch.
This is a good opportunity to test the lights and wiring, before installing the acoustic material and covering the back.
Now we can insert the acoustic material. Sonora® Black Scrim Ceiling tiles are easily trimmed to fit with a sharp knife. They are fiberglass! So… wear gloves minimize exposure to the fibers.
Covering the back of the panel will keep the Sonora® tiles in place, and keep any stray fibers from escaping. This will also make the panel easier to move in the future – without worrying about the tiles falling out or snagging on the wires.
The hardware used to hang the panel will depend on a few different factors – wall construction, stud availability, final panel weight, etc. Make sure you use appropriate hardware for your environment. In this case the final panel weighed less than 30 lbs, and the decision was made to use drywall anchor hooks and industrial hanging eye loops.
Now is a great time to get up and do some creative home improvement projects! Improve the acoustics of your home theater, living room, or home office… and have a cool new focal point for your space.
As people begin to head back into their places of worship, the focus on acoustics has again come to the forefront. Many have been streaming services and listening to music in their homes, where they had short reverb times and good acoustic clarity. They are experiencing a stark contrast in the large reverberant churches to which they are returning. By adding acoustic absorption in a space, you can improve clarity and reduce reflections which can fatigue the listeners.
The Sonora® Panels above are helping to break up the reflections coming from the balcony face and the rear balcony wall, improving the clarity of the voices and the music within the space. This helps to create an intimate and comfortable acoustic environment for those in attendance – and makes it feel more like home.
Hey! Here’s another installation of our new ArtDiffusor® Nouveau™. For this install, these four boards were not only stained, but also framed out to enhance the design aesthetic. From different paints and stains, to mounting techniques, there are limitless possibilities for customization to create your own unique and functional sound diffusing arrays.
The current crisis has forced a large portion of the workforce to operate out of their homes. Daily Zoom and Skype meetings have become a ubiquitous part of our lives. For many of us, this shift is only temporary. However, some companies are seeing the benefits of working at home, and are making plans to move employees to permanent remote positions.
I’m sure all of you have been on a conference call in which a team member’s audio is difficult to understand. This could be caused by a microphone or connection issue, but a large number of intelligibility problems are rooted in a room’s acoustics. Let’s take a look at some common acoustic issues in home offices and how they relate to conference call clarity.
Background Noise – Obviously, it’s difficult to understand speech when there is a lot of background noise. It is vital that you isolate yourself from extraneous sound sources as best you can. Some sources (TV, HVAC) are easier to control than others (traffic noise, pets, children etc.). Make sure your office is “closed off” from intruding noise. Remember, sound is a little like water; it will “pour in” through any openings, such as gaps around doors. If possible, install full perimeter seals and door sweeps to improve sound isolation in your office. If you have sound transmitting through a wall, ceiling or floor, you can consider adding a layer of mass loaded vinyl to the assembly in order to help block unwanted air-borne noise. You can then cover the mass loaded vinyl with SoundChannels® like in this blog.
Reverberation – In simple terms, reverberation is the sound energy that remains in a listening environment as a result of lingering reflections. The reverberation time (RT or RT60) quantifies how quickly an impulse sound decays in a space. Reverberation time is dependent upon the volume and surface materials of a given room. Large spaces with hard materials (tile, drywall etc.) have longer reverberation times, while small rooms furnished with “softer” materials (carpet, drapes etc.) sound more much more “dead”. Speaker phone conversations require a very short reverb time, for optimal clarity, somewhere in the .5s range (half of a second). You can reduce reverberation in your home office with the addition of “fluffy” or irregular furnishings, acoustic panels, rugs, curtains and plants.
Flutter Echoes – Flutter echo, which can be heard as an annoying “ringing sound”, is caused by parallel reflective surfaces. In certain critical listing environments, sound diffusers are used to alleviate flutter echo. Flutter echoes can greatly degrade conference call clarity. This phenomenon can occur between two walls or floor-to-ceiling. To control flutter echoes in your office, you should break up any parallel surfaces with furnishings and/or sound absorptive treatment.
