Modding an SPL Meter
« on: January 02, 2017, 10:51:20 PM »
My spl meter should go down to 30dBc, but even in very quiet environments the best it can do is 50dBc.

I'm assuming it's own self noise is limiting the measurement. Anyone with experience modding these? Or do I just need to buy a higher end model?
