Regulatory Mandates for Pedestrian-Safety Compliance
Australia will require AVAS on all new electric vehicles starting November 2025, adding to mandates already in force across the EU, Canada, and the United States.[1]“Australia to Mandate EV Alert Sounds from November 2025,”, Royal Automobile Club of Victoria, racv.com.au UNECE Regulation R138 compels vehicles to emit artificial noise at 0–20 km/h, specifying minimum sound levels and gradual frequency shifts correlating with speed unece.org. Canada aligned its CMVSS 141 rule set with these guidelines, synchronising safety expectations throughout North America. Such uniform, non-negotiable rules eliminate demand uncertainty for the AVAS market by making acoustic systems a prerequisite for vehicle registration in regulated zones. With every compliance cycle, OEM purchasing departments lock in higher AVAS volumes, anchoring the forward order books of module suppliers.
Rapid Growth in Global EV Production Volumes
In 2024, global electric car production reached 17.3 million units, up 25% from 2023, with China responsible for more than 70% of the total.[2]“Global EV Outlook 2024,”, International Energy Agency, iea.org Each vehicle built in these plants requires an AVAS module, knitting the fortunes of acoustic suppliers to the robust EV growth curve. Model proliferation is also broadening, with the number of distinct electric car nameplates expected to top 1,000 by 2026, including many large SUVs that generate additional acoustic tuning work. Scaling effects are already driving down transducer and amplifier costs, encouraging faster adoption even in price-sensitive segments. Plug-in hybrids further enlarge the target pool because they must still emit artificial sound whenever the internal-combustion engine is off.
Rising OEM Focus on Brand-Customised Exterior Sound Signatures
General Motors signalled the marketing role of AVAS as early as 2012 when the Chevrolet Volt launched with a unique “Pedestrian Friendly Alert,” setting a precedent for branded exterior sound.[3]“The Evolution of EV Sound Design,”, General Motors Communications, gm.com Honda now plans downloadable “vintage performance” sound packs for its 0 Series EVs, turning AVAS into a software-defined revenue stream. Consumer testing shows that listeners prefer familiar, engine-like timbres to common monotone beeps. As premium brands attach emotional value to sound design, acoustic specialists with psychoacoustic expertise gain a competitive edge. The trend reframes AVAS as a brand-experience enhancer rather than a regulatory expense, boosting willingness to pay in luxury segments.
Integration of AVAS with V2X and Smart-City Infrastructure
The United States has earmarked USD 60 million to seed a national V2X network, enabling vehicles to exchange data with roadside units, traffic lights, and cloud services.[4]“National V2X Deployment Plan,”, U.S. Department of Transportation, transportation.govOnce connected, an AVAS module can calibrate output in real time, raising volume in crowded crosswalks and lowering it in quiet residential zones. Academic trials show that networked AVAS cuts reaction time for pedestrians while reducing ambient noise pollution. Chinese municipalities already test context-aware sound modulation in tier-1 smart-city districts, illustrating future opportunities for public-private platforms that fine-tune acoustic environments. Over the long term, integration with V2X will stretch AVAS functionality well beyond its current standalone status.
Restraints Impact Analysis

Lack of Globally Harmonised Sound-Level Regulations
UNECE rules serve as a baseline, yet the United States imposes slightly different spectral and decibel targets under FMVSS 141, obliging OEMs to engineer multiple hardware-software variants. That fragmentation raises validation costs and slows simultaneous global launches because each acoustic profile must pass local certification. Working-group negotiations at GlobalAutoRegs continue, but national priorities diverge between pedestrian safety and community noise control, delaying full convergence. The engineering burden lands hardest on mid-tier suppliers that lack the resources to maintain multiple product lines, thereby tempering short-term growth
Incremental BOM Cost Pressure for Mass-Market BEVs
An AVAS kit adds hardware and software expenses when automakers chase price parity with gasoline cars. The pinch is most acute in entry-level models sold in emerging economies where regulatory enforcement can lag. Research into piezoelectric micromachined ultrasonic transducers promises lower-voltage, higher-output solutions that shrink size and cost, but commercial scale is still several years away. Until those gains materialise, budget-constrained consumers may view AVAS as an unwelcome surcharge, restraining uptake in markets where subsidies are fading.
Segment Analysis

By Propulsion Type: BEV Leadership Reinforces Market Foundation
Battery electric vehicles owned 65.87% of the Acoustic Vehicle Alerting System market share in 2024 and carry the highest forecast CAGR at 14.83%, confirming that fully electric drivetrains remain the prime catalyst for acoustic alerting demand. Because BEVs are silent in every low-speed phase, their compliance windows are broader than those of hybrids, making AVAS non-negotiable. Plug-in hybrids contribute incremental volume because their electric-only mode requires artificial sound below 20 km/h.
Design complexity varies by propulsion. BEVs need continuous output management that minimizes battery drain, while PHEVs must toggle the sound on and off when engines start. Hybrid electric vehicles present narrower activation windows yet still create obligatory volume. Each configuration nuance gives control unit suppliers opportunities to differentiate through software efficiency, further deepening the AVAS market.
