The Global Standardization of AVAS: A Quiet Revolution in Safety
As electric vehicles become ubiquitous, the standardization of AVAS is crucial. Regulations in the EU, USA, Japan, and China mandate similar but not identical requirements for minimum sound levels, frequency ranges, and operating conditions (e.g., speed thresholds).
The goal is to ensure that pedestrians worldwide can consistently recognize the sound of a slow-moving electric vehicle, regardless of its make or model. This creates a universal "audio cue" for safety. Ongoing research focuses on optimizing these sounds to be effective without adding unnecessary noise pollution to urban environments.
FAQ
Q: Do AVAS sounds work for people with hearing impairments?A: They are designed to be effective for a wide range of hearing abilities. The sounds often include lower frequencies that can be felt as vibrations, which can aid those with partial hearing loss.
