TNM 2.5 (effective July 10, 2017)
This noise model is no longer supported by our office.
MnDOT now uses a noise model named MINNOISEV31 rather than the previous version MINNOISE. MINNOISE was a STAMINA based noise model that was modified to use MnDOT heavy truck emission levels and allowed the use of noise berms as well as noise walls. The new model MINNOISEV31 is the same as MINNOISE except that input limits for roadways, barriers and receivers were increased. The new limits can be found in the USERGUIDE referred to below.
