The Electric Motor Horn Market has been estimated to grow from USD 32.1 billion in 2020 to USD 44.3 billion by 2025. Between 2025 and 2035, the market is forecast to expand at a CAGR of 7.2%, surpassing USD 88.6 billion by the end of the period. Regulatory mandates and design shifts toward energy-efficient and compact horn systems have remained key growth determinants across both ICE and electric vehicle platforms.
Federal standards such as those outlined by the Federal Motor Carrier Safety Administration (FMCSA) require that every motor vehicle must be equipped with a horn capable of emitting sound audible under normal conditions from at least 200 feet. Compliance with such safety mandates has prompted continuous product development. According to BossHorn, motor vehicle horns must produce a sound that is both clearly discernible and not unreasonably harsh, underlining the importance of tonal clarity and sound pressure levels in horn selection.

The integration of low-current, high-decibel electric motor horns has been increasingly favored by OEMs focused on modular and sustainable vehicular architecture. These horns, being less susceptible to performance degradation, have been adopted in harsh-use environments such as commercial trucks and electric two-wheelers. The advancement of brushless DC motor technology has supported this transition, enabling reduced power consumption while maintaining acoustic compliance.
Urban noise control programs, particularly in densely populated markets across East Asia and Europe, have driven R&D in directional sound projection and frequency modulation. Manufacturers have introduced dual-tone horns and pitch-adjustable variants to meet varying jurisdictional needs.
In recent trade reports, leading Tier-1 suppliers emphasized that electric horns designed for battery-powered vehicles must also align with vehicle acoustics and overall NVH (noise, vibration, and harshness) calibration.
Additionally, the aftermarket segment has experienced growth with demand for customizable and retrofitted horn systems that adhere to local regulations without voiding OEM warranties. As vehicle platforms evolve, the standardization of compact and compliant horn modules is expected to continue driving innovation and procurement strategies in the global electric motor horn market.
The 110 dB to 118 dB sound pressure segment is expected to lead the global automotive horn market, capturing approximately 48% of total market share in 2025. Over the forecast period from 2025 to 2035, the segment is projected to grow at a CAGR of 7.5%, slightly exceeding the overall market growth rate of 7.2%. This decibel range offers the optimal balance between loudness for effective auditory signaling and compliance with global vehicular noise regulations.
Automakers across regions such as Europe, North America, and Asia-Pacific are increasingly standardizing horn outputs in the 110-118 dB range, ensuring both safety and regulatory adherence. Horns in this range are widely adopted in passenger cars, light commercial vehicles, and two-wheelers for urban and highway driving conditions.
Manufacturers are also incorporating tone modulation and multi-frequency horns within this category to improve sound directionality and vehicle-specific tuning. As cities enforce stricter noise pollution norms, this segment is benefiting from its alignment with urban acoustic limits while retaining effectiveness in high-traffic environments.
Original Equipment Manufacturers (OEMs) are projected to remain the dominant sales channel for automotive horns, accounting for approximately 67% of the global market in 2025. The segment is expected to expand at a CAGR of 7.3% between 2025 and 2035, driven by factory-level horn integration during vehicle assembly and rising global vehicle production volumes.
OEMs are increasingly collaborating with component suppliers to incorporate horn systems that align with platform-specific design and safety requirements. These systems are often tested and validated for durability, water resistance, and temperature tolerance to ensure long-term functionality.
Furthermore, electric vehicle (EV) platforms are demanding specially tuned horn acoustics due to quieter drivetrain noise, reinforcing the importance of OEM-level acoustic engineering. Regulatory compliance related to pedestrian alert systems is also encouraging integration of standardized horn outputs as part of vehicle homologation processes. The trend toward embedded acoustic safety features is reinforcing the OEM channel’s dominance in delivering performance-assured horn systems.
Challenge
Noise Pollution and Regulatory Constraints
Regulatory limitations on noise pollution from vehicles pose one of the greatest challenges to the electric motor horn industry. Governments globally are imposing stringent sound limits on horns to curb urban noise pollution, especially within residential and commercial areas.
Manufacturers must innovate and come up with horns that provide enough safety notification while reducing noise disturbance in order to meet such regulations. The expense of developing and incorporating advanced noise-control technologies into electric horns contributes to production costs, making affordability and mass adoption challenging.
