Multi-criteria analyses use scoring and weighting systems based on criteria to test and compare alternatives. The table below shows a variety of different scoring systems, using noise as the criterion (Lee, 1987):

scoring method Basis of score
A B C D
absolute 65 62 71 75 Measured L10dBA levels
interval 0 -3 6 10 Difference in L10dBA levels using alternative A as a base
ordinal B A C D Ranking according to ascending L10dBA levels
binary 0 0 1 1

0 = less than 70 L10dBA; 1 = more than 70 L10dBA
