<font color='#000080'>Considering most people never bother with SPL meters, you will be lightyears ahead by having one at all. I use the digital - be sure to set it to slow response.
If I had to do it over, I may select the analogue as it would be easier to read. The needle is better than the digital number, IMO.
I have not heard that one is 'more accurate' over the other, but I suppose I could test that.</font>
