Message The meter can only read from 50-115 that is why I have no readings below 50.

The table was 2 sets of numbers for the A and C readings, so the first 2 are A readings the second 2 are C. (I will put this into excel tomorrow for anyone interested, email me.

There are actually 3 major sound readings A, B and C. A is most common, as you see most readings listed as dba since that is what most people can hear. The C rating is also used frequently as this calulates in background noise and reads the entire sound spectrum which includes those sound levels only felt that are not audible. If you need more info, email me and I will suggest a book tomorrow when I am in my office that explains everything.
