Noise Levels of DAS Antenna Equipment

A study completed by Hammett & Edison, Inc, Consulting Engineers,  shows that the maximum calculated noise levels from this equipment at a distance of 25 feet will be 40.0 right, 42.2 front, 40.1 left and 39.5 dBA back.    Combined with the ambient noise (called “local ambient level of no less than 40 dBA), the equipment sound will be audible with an increase of  +3.0 dBA right, +2.0 dBA front, +3.0 dBA left and +3.3 dBA back.
