In an effort to provide students with a better way to record audition (for movie narration, video reflections, screencasts, and so forth) I have experiments with a few ideas.
Let me preface this by saying I have no illusions about the audiophile quality of these experiments, they are by no means perfect. What they are, instead, is a way to lesson the din of a classroom, and improve sound quality, when recording audio. My sound booth solutions will win no acoustic awards but they do a surprisingly good job in a few areas:
- limiting background noise
- providing more depth/richness to the student's voice since it forces them to be closer to the iPad/laptop microphone
- make everyone else in the room more aware of recording happening
- it was surprising to see how quiet the rest of the room got when everyone noticed the cubes being used
I have taken 3 closets and converted them into "sound booths" which I will cover in another blog post shortly. The problem with the closets are they are closets; they are fixed to a room, they are usually used for other things, like closet things, and they take a lot to convert into a reasonable sound booth.
I was aiming for a less expensive, portable solution. To that end I used extra foam purchased for the bigger closet project and some extra Ikea storage bins I had at home and created 3 portable "audio cubes" for students to record sound.
How I did it...
Velcro, acoustic foam, Ikea cubes...
I took 24x24 pieces of Pyramid foam and cut them to 6x6 (6 triangles by 6 triangles) for the 2 sides of the cube and 5x5 for the top of the cube. I used one SonoPanel for the back of the cube. Left the bottom empty for placing the student device:
Cubes in action:
- Storage cubes
- Ikea: Drona
- $4.99 each
- $27.99 per box (used a single box)
- Auralex Acoustic foam
- Sono Flat Panel
Yes, the acoustic foam is expensive. I probably didn't need the SonoFlat panel piece (but it looks cool). With the $269 investment I've gotten 3 closest and 3 cubes done with about 1/2 of the case left over.
So it's a roughly $350 investment and some time but you can get a ton of flexible and portable audio recording solutions out of it.
I will be posting a write-up of how I built the audio closets shortly.
