Fun with materials.

What happens when you put an accelerometer on a piece of MDF and hit it with a ballpeen hammer. Lets take a look.

Audio spectrum 64K point FFT of piezoelectric acclerometer with CLIO.

Love hitting stuff and see what happens! :)

Nick B:
That’s an interesting and fun test.... and also useful if you’re having a bad day  :D 🔨 

jimbones:
Hal, I want to get some accelerometer's to start experimenting, could you recommend some?

HAL:
Digikey has one like the Audiomatica CLIO version that needs power to run.  Has a different connector, so will not work directly with CLIO.  It does have sensitivity data usually.

They sell a preamp, but that has a lot of gain that might not be what is needed.

Hope that helps.

Thank you Hal for performing the experiment and sharing the results with us. The results are quite interesting.
May I ask the type, thickness, size of the MDF? If proprietary, I understand.

Cheers and great weekend.
