Electric Vehicle Sound Generator Market Size

The global electric vehicle sound generator market size was valued at USD 1.5 billion in 2024 and is estimated to register a CAGR of 10% between 2025 and 2034. The demand for electric vehicle sound generators (EVSGs) is being fueled by the growing popularity of electric vehicles (EVs) as the former remain technically quiet at low speeds. By the end of 2024, total sales of electric vehicles reached 17.1 million, signifying a 21% increase year on year.
 

In December 2024, sales hit an all-time high of 1.9 million, indicating an increase of 26% compared to December 2023. Electric vehicles, unlike vehicles with internal combustion engines, emit no or very low noise, making it difficult for pedestrians to detect them in urban areas. Therefore, artificial sound systems are now being used for the detection of EVs and have now also become a necessity to ensure pedestrian safety of issuing regulations.
 

Furthermore, mandates have been issued globally, requiring EVs to produce a certain sound at low speeds, which further leads to adoption of EVs with the implementation of EVSGs. With growing manufacturing and sale of EVs, from two-wheelers to commercial fleets, EVSGs are now becoming an accepted standard feature.  The alignment of EV expansion and demand for sound generation is primarily high in densely populated regions with heavy pedestrian traffic, where safety concerns are heightened.
 

Regulatory measures for pedestrian safety are another major feature contributing to the rising demand for EVSG market. Government authorities in major countries including the U.S., EU, and Japan have enacted laws necessitating that EVs emit sound warnings at low speeds to alert pedestrians, especially the visually impaired. Conforming to FMVSS 141 and UN ECE R138 standards has made EVSG installation compulsory for manufacturers. As a result, EVSGs have now moved from an optional feature to core feature in most electric vehicles, thus driving its adoption across industry.
