Thanks, though it seems like the list contains corded tools and none of the models I’ve been considering. It also looks like the sheet only lists sound power level, i.e. something like overall loudness. While lower sound in general is of course good, what I’m trying to find is a drill driver that doesn’t have as high pitched sound as most 18V tools do. For example both DCD791 and DDF484 have a listed SPL of 76 dBA, but I found the noise from the DDF484 to be more annoying due to it having higher frequency.
