I am trying to do some measurements using a Radio Shack Digital SPL Meter to get some values in order to assist me in determining speaker placement. I used the Alan Parsons Soundcheck2 CD as the source for the levels. After doing so, was getting ready to either pitch my speakers, the meter, or commit Hari-kari (maybe all of them).
I then remembered that the RS meter has some issues with regards to accuracy (it's been awhile since I've done this). Googled and found a bunch of correction values, all generally within a few db of each other, however, they are mostly for the older analog meter.
So, 2 questions:
1) Are the Analog and Digital versions of this meter roughly the same (i.e., can I use correction values for the Analog meter for my Digital meter)?; and
2) Is there a concensus on the correction values to use? I got my numbers from this site,and it seems roughly the same as several others.http://diyaudioprojects.com/Testeq/RadioShack_33-2050/33-2050.htm
