WebbIn general, uncertainties should preferably be determined following the principles laid down in ISO/IEC Guide 98-3, the Guide to the expression of uncertainty in measurement (GUM:1995). According to current knowledge, it seems impossible to formulate these models for the different quantities in building acoustics. Therefore, the concepts of … Webbwe add the fraction uncertainties of the involved quantities. Take the following example: a = 2 ± 0.2 & b = 3 ± 0.3 We are given, c = b/a Find the absolute uncertainty & percentage uncertainty in c. c = 3/2 = 1.5; in case powers are involved: when powers are involved in the given expressions, we find the uncertainties in the same way as above ...
