Talk:Robinson-Dadson curves
From Wikipedia, the free encyclopedia
[edit] confused
There are two significantly different graphs, with both the same labels on the axes and description. Shouldnt it explain somewhere what the difference is? 217.166.90.180 09:23, 8 April 2006 (UTC)
Look again - the descriptions are different! One is clearly marked Robinson-Dadson and the other Fletcher-Munson. The debate over the difference is fully described here and on the associated pages. Both are compared with the new ISO standard, which supercedes them. --Lindosland 13:19, 24 June 2006 (UTC)
