As I begin thinking of things I want to do in my classroom next year, I turned towards audio and video. I want my class to be heavily intertwined with projects. One of the issues I repeatedly see in classrooms is poor sound quality on student videos. What could I do to help with narration or voice overs in student projects? I did a little research on this and I found a DIY $20 solution. I made my own sound booth from an 18 gallon tub, a twin size “egg crate” mattress pad, and spray adhesive.
Now that I have the booth made it’s time to test it. I have a SnowBall microphone for the booth. My students will have Chromebooks to record their audio. The great thing about the Chromebook is you can connect USB microphones and they work great. If you do not have external microphones to use, you could simply place the Chromebook in the booth to record using the default microphone.
There are a number of apps available to record and edit audio on the Chromebook. For this test I used AudioRecorder. It is a simple app to record and save audio as a wav file. This app also works offline. So here are the test audio files.
Without the sound booth
Using the sound booth
I believe there is just enough of a difference for the audio to sound clear and full. If you are interested in taking about 15 minutes to create a DIY sound booth for your classroom, here is the video tutorial I used to make mine.
The only thing I didn’t like the tutorial is I did not cut the hole in the bottom to set the microphone in. with the SnowBall mic there was enough stability that I didn’t feel I needed the hole.
So if you try this, I want to hear from you. Comment below with your experiences. Also, if you use Chromebooks, what apps are you using for audio recording and editing?
