I have the following SPL meter that was given to me. I was wondering how it compared to the Radio Shack SPL meter and it being digital would it work okay with my AVIA DVD?
There are 2 things that I question. The frequency response only measures down to 30hz, that won't be low enough, but I couldn't find the specs on the Radio Shack model so I don't know if it measures lower. The other is the accuracy, is +/-2dB acceptable?
Any suggestions or advice is appreciated.
Guy Kuo, I'd really like your response if possible.
Thanks,
