8th grade science project

Room Acoustics Forum by Rives Audio

Welcome! Need support, you got it. Or share you ideas and experiences.

I'm looking for some ideas on how to set up a science fair project for my son that explores the differences in construction materials for attentuating sound. I've built a good many home made sound panels for my room but here's what I'm thinking:

Build a small box about 2' x 2' x 2'. Mount a speaker on sone side firing in. DRive with a signal generator. Install a SPL meter inside the box and line the box with different materials like plain sheetrock, wood, FG, foam, carpet, etc. etc. Record spls at varying frequencies w/varying materials and graph.

Any better ideas or improvements would be greatly appreciated. I need to keep it simple enough and not to big but make meaningful at a basic level.

Regards,
Jim D.
