I would like to know how I can measure the vibration coming from my hand shaking something. My experiment is like this. I put a ball made of strong glass into a closed empty box made of strong glass too. The box is small enough for me to be held with one hand. I have to shake the box with one hand so that the ball is bouncing inside and produce sound.
How do I measure how often (or how intense?) the sound comes out in one minute? This definitely cannot be done just by ear. I know this is a matter of vibration as the slower I shake the less intense the sound is produced. What tool must I use?
Knowing this will help my project a lot as I plan to include it in a competition. I searched in google/youtube and found something called vibrameter I believe? Or vibratometer? I forget but I couldn't understand how to apply it in my case. Also, my physics memory cannot seem to recall any tool useful for this.
