A breakthrough in noise reduction technology could make electric vehicles quieter without relying on active sound systems. Researchers have developed particle dampers designed to absorb vibrations in electric vehicle inverters, a common source of unwanted noise. These passive systems could improve comfort for passengers and reduce environmental noise pollution. The innovation may also simplify vehicle design by eliminating the need for complex electronic sound masking.
