London, Ontario based Resource Stage has some great free printable resources on all things audio.
The articles that seemed most helpful for schools are:
- Evaluating And Comparing Speakers
- Your Simple Audio System Cheat Sheet
- Glossary of Audio Terms
- Portable Sound Systems
The only problem is that they’re a bit tricky to find. You want to click on the icon in the top right corner that looks like a folder. I’ve circled the icon you’re looking for in red on the graphic above.
Tip of the hat to the CODE (Council of Ontario Drama and Dance Educators) blog.
