Figure 7 Values of the upper extreme of the 95% confidence interval [L’p,A,eq + U(L’p,A,eq)] based on Flat, Triangle, Rising, and Falling environmental noise spectra (see Figure 5). Calculations performed according to: the empirical method (E); the analytical full method applied to experimental values found in this work (AF); the analytical simplified method applied to experimental values found in this work (AS); the analytical simplified method applied to values found using manufactured-declared values according to ISO 4869-1 (ASI).
