Abstract:Multi-microphone measurements of the passby noise emissions from three dedicated multi-axle trucks and from transient trucking were made at nine highway sites and one standard (SAE-J366b) measuring site. Measurements were made in and around Fort Wayne, Indiana, at sites of varied unobstructed configurations. Included in this report are tabulated peak RMS noise levels measured, curves of A-weighted noise levels versus offset distance, graphic noise level time history recordings, and 1/3-octave frequency spectra versus offset distance for selected events.
