Ai measurement Location 2, 75 P. from the centerline of the wicks. <br /> the highest I.mary noise ICrcl due to tram passbcs without horn noise vvas measured to be <br /> 89 dBA. This L,,,a, sound lere1 occurred during lour separate train passbys. <br /> At the planned minimum setback or 57 It. from the tracks. the L,,,a, noise level <br /> increases to 91 dBA. Tl-e exterior 1_,,,.,, value at the building setback is the noise level <br /> from which the interior 1-max ralue is calculated. <br />
