For the purpose of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.
A-WEIGHTED SOUND LEVEL. The sound pressure level in decibels as measured on a sound level meter using the A-weighing network. The level so read is designated db(A) or dBA.
DECIBEL or db. A unit for measuring the volume of a sound, equal to 20 times the logarithm to the base ten of the ratio of the pressure of the sound measured to the reference pressure, which is 20 micropascals (20 micronewtons per square meter).
MOTOR VEHICLE. Consistent with IC 9-13-2-105, a vehicle that is self-propelled. The term does not include a farm tractor, an implement of agriculture designed to be operated primarily in a farm field or on farm premises, or an electric personal assistive mobility device.
NOISE LEVEL. The A-weighted sound level produced by a motor vehicle.
PERSON. Any individual, association, partnership, or corporation which includes any officer, employee, department, agency or instrumentality.
SOUND LEVEL METER. An instrument which includes a microphone, amplifier, RMS detector, integrator or time averager, output meter, and weighting networks used to measure sound pressure levels. The instrument shall be used for measurement of the intensity of sound and calibrated in decibels as standardized by the American National Standards Institute (ANSI). Readings shall be made on a db(A) scale.
TRAFFIC NOISE. Sound made by a motor vehicle operated either on the public right-of-way or private property.
