Yes, I don't know if you read the paper I posted but it said:
Efforts to reduce the noise emitted by vehicles have been ongoing. In 1997, the
average sound level for passenger cars was about 90 dBA (Wiener, 1997).
Currently, U.S. automobile manufacturers design cars to meet the European noise
limit of 78 dBA [Federal Highway Administration (FHWA), 1995]. The U.S.
Federal-Aid Highway Act of 1970 mandated FHWA to develop noise standards for
mitigating highway traffic noise (FHWA, 1995).
Other efforts have focused on quieter tires and pavement. Purdue University’s
Institute for Safe, Quiet and Durable Highways has conducted federally funded
research to design tires that make less noise (Wiebusch, 2001). Arizona is
involved in a Quiet Pavement Pilot Program with a modified highway surface. In
initial tests, this surface reduced moving vehicle noise by 3 to 12 dBA
compared to conventional surfaces (Manuel, 2005).
Hogan (2008) studied pedestrian injuries involving hybrid vehicles. This
analysis was principally based on data from the U.S. Fatality Analysis
Reporting System (FARS), which captures data on all U.S. motor-vehicle-related
deaths occurring in public, from 2001 to 2006.
The analysis showed that, based on reported incidents, hybrids are no more
dangerous to pedestrians than other vehicles, and little variation exists in
how and why blind or sighted pedestrians die in vehicular incidents.

The National Federation for the Blind (NFB) and the American Council of the
Blind have been vocal regarding the perceived hazard of too-quiet vehicles
because blind people use the sounds of traf c to determine when it is safe to
cross streets (Sau- erburger, 2008). These organizations have lobbied the
government and vehicle manufacturers to build in some type of obvious noise
when a vehicle is in quiet, low-speed opera- tion (NFB, 2010).
