Acoustic Vehicle Alerting System Market - Global Forecast 2025-2030

The Acoustic Vehicle Alerting System Market size was estimated at USD 1.31 billion in 2024 and expected to reach USD 1.45 billion in 2025, at a CAGR 10.35% to reach USD 2.38 billion by 2030.

The transition to electric and hybrid mobility has created a paradox of safety and silence on public roads. While electric drivetrains deliver near-silent operation, this quietness poses a heightened risk for pedestrians, cyclists, and other vulnerable road users who rely on auditory cues to anticipate approaching vehicles. Regulatory bodies worldwide have recognized this gap and established mandatory Acoustic Vehicle Alerting System (AVAS) requirements to mitigate potential collisions and enhance urban safety. At low speeds, when tire and wind noise are insufficient, these systems generate artificial sounds designed to alert pedestrians without contributing to unnecessary noise pollution. Consequently, AVAS technology has evolved from an optional enhancement to a baseline safety feature for next-generation vehicles.

Driving this safety imperative is the Federal Motor Vehicle Safety Standard No. 141 in the United States, which mandates that hybrid and electric vehicles emit audible warnings until they reach 30 km/h. Issued in December 2016 and phased in through September 2020, this standard has compelled manufacturers to integrate robust speaker and control unit assemblies with consistent firmware across model lines, ensuring seamless compliance under the Pedestrian Safety Enhancement Act. Simultaneously, international harmonization efforts under UNECE Regulation R138 define detailed test procedures, spectral requirements, and minimum sound thresholds for speeds up to 20 km/h, further solidifying AVAS as a global safety linchpin.

Behind these regulatory frameworks lies a surging wave of electric vehicle (EV) adoption. According to the International Energy Agency, first-quarter EV sales in 2024 soared by approximately 25% over the same period in 2023, pushing total annual EV sales beyond 17 million units globally. This acceleration extends AVAS demand across diverse vehicle categories, from compact two-wheelers in Southeast Asia to heavy-duty electric buses in North America. With each electrified platform requiring dedicated acoustic modules, the AVAS market is firmly anchored to the broader electrification trajectory, promising sustained growth as OEMs and regulators converge on unified safety objectives.

The AVAS landscape is being redefined by successive waves of regulatory refinement, technological convergence, and infrastructure connectivity. In January 2025, the 02 Series of Amendments to UNECE Regulation R138 took effect, incorporating enhanced test metrics, clarified activation speed ranges, and standardized measurement protocols to address practical deployment challenges encountered since the rule’s 2018 inception &#10. These revisions mandate more precise frequency-shift requirements and stricter noise-level consistency checks, compelling suppliers to optimize transducer performance and acoustic calibration methods for global applicability.

Meanwhile, divergent technical nuances between UNECE and U.S. mandates have spurred innovation in component design. UNECE R138 stipulates sound output up to 20 km/h and permits optional continuous operation beyond that threshold, while FMVSS 141 extends mandatory alerts to 30 km/h with prescribed volume shifts at each cruising speed. Designers now reconcile these differences by developing configurable control algorithms that dynamically adapt acoustic profiles per jurisdiction, deploying multi-path compliance strategies that reduce development cycles and hardware variants.

Complementing regulatory drivers is the emergence of connected infrastructure. The U.S. Department of Transportation’s August 2024 National Deployment Plan for Vehicle-to-Everything (V2X) technologies earmarked a comprehensive roadmap for integrating AVAS with roadside units, traffic signals, and cloud-based analytics. Seed funding of nearly $60 million allocated to Arizona, Texas, and Utah through FHWA grants underscores a shift toward context-aware alerting, where AVAS modules can modulate volume in real time based on pedestrian density, crosswalk occupancy, and environmental noise levels. This fusion of V2X and AVAS heralds next-generation safety services that transcend standalone hardware, positioning acoustic alert systems as intelligent nodes within connected ecosystems.

At the technological frontier, manufacturers and specialist suppliers are investing in AI-driven sound modulation. Adaptive acoustic algorithms leverage vehicle-state data and environmental inputs to tailor alert signals, optimizing audibility while minimizing urban noise footprint. Pilot programs in European and Asian smart cities have demonstrated that AI-enhanced AVAS can reduce unnecessary sound output by up to 30% without compromising detection times for pedestrians. As these capabilities mature, AVAS solutions are poised to deliver personalized sound experiences that align with brand identities, safety standards, and community noise ordinances, marking a transformative shift from static beeps to dynamic, low-impact soundscapes.

Trade policy developments in 2024 and 2025 have introduced new cost considerations for AVAS supply chains, particularly for imported components and modules. In May 2024, the Biden administration quadrupled Section 301 tariffs on EV imports from China, raising rates from 25% to 100% to curb subsidized competition. Concurrently, tariffs on lithium-ion EV batteries increased from 7.5% to 25%, while allied battery parts and critical minerals faced similar hikes by 2026. These measures aim to incentivize domestic manufacturing but also elevate input costs for acoustic transducers, amplifiers, and control electronics that rely on imported materials and subassemblies.

The ripple effects on suppliers came into sharp focus when LG Energy Solution forecasted a slowdown in EV battery demand into early 2026, attributing part of the downturn to tariff headwinds and the imminent end of federal purchase incentives. Despite posting strong Q2 earnings, the company flagged potential underutilization of U.S. battery lines, prompting strategic redeployment toward energy storage systems to offset reduced EV volumes. For AVAS component manufacturers tied to battery pack production sites, this shift underscores the importance of geographic diversification and in-region partnerships to mitigate tariff exposure and policy-driven demand fluctuations.

Automakers are absorbing some of these costs to maintain competitive pricing. General Motors declared it would not raise sticker prices despite a $1.1 billion tariff impact, leveraging manufacturing efficiencies and localized production to shield consumers from direct cost pass-through. However, incremental incentives on legacy models are tapering, hinting at potential price adjustments of 4%–8% within 2025 as manufacturers balance margin preservation against volume objectives.

European-headquartered Stellantis experienced direct tariff charges totaling roughly €300 million during the first half of 2025, contributing to an expected net loss of €2.3 billion. The company cited 25% tariffs on non-U.S. assembly and paused cross-border supply flows as key factors in operational disruptions. These cost pressures have prompted Stellantis to accelerate nearshoring initiatives, restructure platform investments, and refine AVAS sourcing strategies to maintain regulatory compliance without sacrificing profitability amid evolving trade landscapes.

Drawing from a holistic segmentation framework reveals nuanced opportunities and challenges across AVAS market dimensions. Propulsion-driven dynamics illustrate that battery electric vehicles lead demand due to their prolonged silent operation, while fuel cell and hybrid configurations require more intermittent alert functions, influencing control unit sophistication and power management strategies. Plug-in hybrids present unique toggling requirements, prompting advanced software calibration to seamlessly engage AVAS only during electric-only driving modes.

Vehicle category segmentation demonstrates divergent requirements between commercial and passenger applications.
