The State of New York has announced a statewide ban on such operations. Buffalo, NY and Pittsburgh, PA have announced a ban. Colorado has numerous activities to stop fracking.
Roadway noise is the collective sound energy emanating from motor vehicles. It consists chiefly of road surface, tire, engine/transmission, aerodynamic, and braking elements. Noise of rolling tires driving on pavement is found to be the biggest contributor of highway noise and increases with higher vehicle speeds. [1] [2] [3]
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks.

The Illinois Highway Code (605 ILCS 5) states that all state highways are to be numbered and that no state highway shall go unnumbered. [2] In addition, roads in the system include state highways that connect
Active noise cancelling (ANC) is a software process that uses existing in-vehicle infotainment hardware to eliminate undesirable noise within the interior of a vehicle. This elimination technique is known as harmonic order reduction, where unwanted audio signals are identified by sensors and filtered out of the overall interior vehicle sound. [3]
