Air and Electric Horns represent two primary technologies in automotive sound systems. Air horns, commonly used in heavy-duty vehicles, deliver high-volume sound using compressed air. Electric horns, however, dominate passenger vehicles for their reliability and compact design. Technological improvements have led to hybrid systems combining both features for enhanced performance. These horns are designed for varying frequencies to ensure audibility in all traffic environments, maintaining road safety while meeting regulatory standards for noise control.

Vehicle Acoustic Alert Systems (VAAS) are becoming mandatory for electric and hybrid vehicles. They emit artificial sounds to warn pedestrians of approaching silent vehicles.

Key Features

  • Frequency modulation for audibility.

  • Weather-adaptive sound output.

  • Compliance with global EV regulations.

Market Impact

VAAS is a major driver of innovation, expanding the horn system’s role beyond conventional safety.

FAQs

Q1: Why are VAAS needed?
To alert pedestrians around quiet EVs.
Q2: Are they standardized?
Yes, under international safety norms.
Q3: Can sounds be customized?
Yes, within regulatory limits.
