Electric vehicles (EVs), as the name suggests, have an electric motor which makes them one of the quietest means of transport. Hybrid vehicles produce internal combustion engine noise and are therefore far louder than EVs, the silence is often considered an advantage for cabin comfort, it poses a significant danger to pedestrians, especially the elderly and disabled. Acoustic vehicle alerting systems (AVAS) are now required by law in the US, EU, Japan, and China IV. These systems generate artificial sounds at low speeds to alert pedestrians. Coupled with the double-digit growth in global EV production, that is helping propel the demand for vehicle sound synthesis systems.
 

For instance, the European Union (EU) has had regulations in place since 2019 for EVs and hybrids requiring them to make warning sounds when driving below the threshold of 20 km/h. U.S. counterparts with the national highway traffic safety administration (NHTSA) have similar provisions in which vehicles operating below 30 km/h are subjected to the same standard. Such provisions are not merely recommendations but rather effective laws which need to be complied with by automakers. This brings forth the notion of sound synthesis technology as a market driven necessity. With the adoption of stricter safety regulations by countries and regions, particularly in core urban areas, the use of such technologies becomes mandatory fueling expansion into new markets.
 

Contemporary automotive manufacturers focus on sound design to create emotional interactions to make brand association and increase visibility among users. Vehicle sound synthesis now expands beyond safety to branding and the broader sensory ecosystem of an electric vehicle. OEMs are developing unique audio profiles for their vehicles, including muscle car roars, space-age hums and soothing melodies. BMW, Tesla and Mercedes-Benz are examples of manufacturers who contracted sound designers and composers to tailor such experiences. Enhancing and differentiating the customer experience through sound integration not only improves the experience but also shifts market strategies towards a premium differentiator in an increasingly competitive EV market.
 

For instance, in June 2022, the change of sound design into a brand and experience identity tool is exemplified by BMW's partnership with award-winning film composer Hans Zimmer. As part of BMW’s iconic sounds electric initiative, Zimmer was commissioned to compose unique electric soundtracks for BMW’s EV line.

Global Vehicle Sound Synthesis Technology Market Analysis

Based on product, the market is segmented into internal sound system and external sound system. In 2024, the external sound system segment held a market revenue of over USD 950 million.
 

• As autonomous driving systems in the car industry advance and the shared economy model takes hold, exterior sound is becoming increasingly necessary for human-machine interaction.  One method used by automobiles to alert pedestrians of their presence is honking.  Arousal is provided via sound synthesis in self-driving automobiles, which frequently lack a driver to activate a signaling horn.  As a result, external sound systems must be considered a significant, feature-rich, and revenue-generating technology.
   
• Due to the legal repercussions of being non-compliant, automakers are directing their research and development, as well as legal budgets, to external systems. Because these systems are required and standardized, original equipment manufacturers are switching to mass production which makes them more competitively priced and easier to obtain. This scope of deployment provides external sound systems with a competitive advantage over less mandatory internal sound alternatives.
   
• Vehicles such as delivery vans and even low-cost electric cars are equipped with external sound systems because of mandatory safety regulations. On the other hand, internal sound systems are popular among luxury vehicles but this reduces the market share. Generally, external systems yield higher profit, as their adoption propels market growth.
   
• For instance, in July 2024, all new electric and hybrid cars in the European Union must have external sound systems that operate below 20 km/h. The U.S. NHTSA also requires such systems for speeds below 30 km/h.

Based on propulsion, the market is divided into an internal combustion engine and electric vehicles. The electric vehicles segment held a major market share of 74% in 2024 and is expected to grow significantly over the forecast period.
 

• Battery electric vehicles, or BEVs run on an internal combustion engine and are silent in nature. BEVs are different from hybrid electric cars (HEVs) or plug-in hybrid electric vehicles (PHEVs) in that they are completely electric and do not require any kind of engine.  While a completely silent cabin increases passenger comfort, it poses a serious risk to walkers and other active non-vehicular travelers. 
   
• BEVs mostly rely on external sound synthesis devices, such as the acoustic vehicle alerting devices (AVAS), to improve safety features and reduce the chance of accidents.  These systems are regarded as the most advanced adopters of technology because of their heavy dependence on artificially generated engine noise. Sedans evolve toward more intelligent and connected platforms; FCCs are combined within the power distribution units to protect low-voltage systems and ensure uninterrupted operation. Their integration ensures that main functions such as navigation, climate control, and safety sensors work reliably without electrical interruptions.
   
• Fuel cell vehicles, or FCEVs, have traditionally lagged other types of electric vehicles (EVs) in terms of infrastructure, and the stagnation of hydrogen-focused policies is a large determining factor. Auxiliary electric driven vehicles (AEDVs) have also confronted a similar lack of focus policies which have kept their type stalled in comparison to fully electric vehicles. 
   
• The development of this submarket has been greatly shaped by worldwide regulatory policies that particularly mandate the integration of sound systems on BEVs for superficial audio output at lower speeds. Europe, the USA, Japan, and China have enacted such protective legislation requiring these regions to device low speed collision mitigation sounders on BEVs, which require the vehicle to produce sounds at low speeds to aid in collision avoidance. Thanks to these policies, every new BEV is sold with vehicle sound synthesis technology in these regions, therefore, increasing market income.
   
• For instance, In January 2024, Nissan launched the updated 2024 LEAF, which continues to feature its Vehicle Sound for Pedestrians (VSP) system. This artificial sound technology emits external alert tones at low speeds to increase pedestrian safety, along with global AVAS regulations. It helps in VSP functionality as part of its broader EV safety and compliance framework reinforcing Nissan’s commitment to urban road safety.

At the same time, regulatory bodies concerned with pedestrian safety are trying to quiet the existing traffic noise, which draws their attention to electric and hybrid passenger vehicles that are mostly inaudible operating at lower speeds.
   
• Electric passenger cars in politically and economically developed regions such as the European Union, United States, China, and Japan will now have to come equipped with acoustic vehicle alerting systems (AVAS), a system that artificially alerts people of the vehicle's movement since it operates silently. Such measures, focused predominantly on the passenger vehicle market, have extensively increased the market for sound synthesis technology in this category.
   
• The volume of sales of passenger cars as compared to commercial vehicles has greatly fueled the growth of this segment. Automobiles such as the Tesla Model 3, Hyundai Kona Electric, and Volkswagen ID.4 have also shifted the market towards BEV which increases the demand for both integrated sound synthesis software and hardware. Competition in the market for EV passenger cars also contributes to the large-scale production and mass standardization of AVAS (Automated voice alert systems) systems in electric passenger cars. Each of these systems requires associated hardware and custom compliant sound output software which is not commercially feasible when compared to the lower demand for servicing commercial vehicles.
   
• For instance, in March 2024, sales of passenger vehicles remain significantly higher than those of commercial vehicles. The OICA estimates that over 66 million passenger vehicles and 25 million commercial vehicles were sold in 2023. The bulk of electric vehicles sold are categorized as passenger vehicles, the demand for hardware components such as AVAS speakers, control units, and sound modules is higher.
