Current through June 11, 2024
New motor vehicles tested for compliance with NAC 484D.155,
				  together with any auxiliary equipment that would be in use while the vehicle is
				  in motion on the highway, must be operated as follows:
1. Trucks, truck-tractors and buses that have
				a manufacturer's gross vehicle weight rating of 6,000 pounds or more must be
				operated under the condition of grade, load, acceleration, deceleration and
				gear selection that is found to give the maximum noise at a speed up to 35
				miles per hour.
2. Trucks,
				truck-tractors and buses that have a gross vehicle weight rating of less than
				6,000 pounds and passenger cars must be tested at curb weight plus weight of
				the driver and when necessary one technician, and be operated as follows:
(a) Motor vehicles equipped with three-speed
				or four-speed manual transmissions must be operated in second gear. Vehicles
				equipped with four-speed manual transmissions must also be operated in second
				gear. Vehicles equipped with five-speed manual transmissions must be operated
				in second gear. Vehicles equipped with automatic transmissions must be operated
				with transmissions engaged in low gear. Vehicles which reach maximum rated
				engine speed at less than 30 miles per hour or before reaching a point 25 feet
				beyond the microphone line must be operated in the next highest gear. Auxiliary
				step-up ratios or overdrive must not be engaged on vehicles so
				equipped.
(b) The vehicle must
				proceed along the test path at a constant approach speed of 30 miles per hour.
				When the front of the vehicle reaches a point 25 feet from a line through the
				microphone intersecting the path of the vehicle at right angles, the throttle
				must be fully opened. The throttle must be held open until the rear of the
				vehicle is approximately 100 feet beyond the microphone, or until the maximum
				rated engine speed is obtained at which point the throttle is gradually closed.
				Wheel slip must be avoided during this test.
Nevada Administrative Code › Chapter 484D - Equipment and Size, Weight and Load of Vehicles › EQUIPMENT OF VEHICLES › Noise Emission Standards › Section 484D.185 - Noise emission measurements: Vehicle noise level

Current through June 11, 2024
The measured noise level of a vehicle must be reported as
				  follows:
1. The sound level reading
				for determining compliance with NAC 484D.150 must be the highest reading
				obtained as the vehicle or combination of vehicles passes through the measuring
				site on the highway. Sound level readings must be recorded on vehicles which
				are in lanes of travel with centerlines at or beyond 50 feet and which produce
				noise levels exceeding the regulatory limits.
2. The sound level readings for determining
				compliance of new motor vehicles with NAC 484D.155 must be obtained by making
				at least four measurements for each side of the vehicle. Sufficient preliminary
				runs must be made to familiarize the driver with the operation of the vehicle
				and to stabilize the engine operating condition. The A-weighted sound level for
				each side is the average of the two highest readings on that side which are
				within 2 dB of each other. The noise level reported for the vehicle must be the
				sound level of the loudest side of the vehicle. Obvious vehicle malfunction
				nullifies the test.
3. Tolerances
				are necessary due to unavoidable variations in test site, vehicle operation,
				test equipment, temperature and wind gradients, and inherent differences in
				nominally identical vehicles. Vehicles specified in NAC 484D.150 may not be
				considered in violation unless they exceed the limits in that section by more
				than 2 dB. New vehicles must be designed to comply with the limits in NAC
				484D.155 at the time of manufacture to ensure that the vehicles will not exceed
				those limits plus a 2 dB tolerance when tested by an enforcement
				agency.
