According to the authorities, Electric Cars must emit some sort of sound, whether artificial or natural, to warn neighboring residents. According to a new set of standards put forth by the Automotive Industry Standards Committee of the Central government, electric automobiles will soon be required to generate some sort of sound, either naturally occurring or created artificially, to alarm adjacent walkers and persons (AISC)
Both passenger automobiles and freight carriers must abide by the rules. The Technical Standing Committee of the Central Motor Vehicles Rules, 1989 may soon incorporate these most recent draught standards.
The new regulations require EV makers to modify their powertrains so that they emit some sort of sound when moving. If this can’t be done, a loud speaker-like device called an Acoustic Vehicle Alerting System (AVAS) needs to be placed.
However, the issue is that adding a loud speaker could further deplete the battery at a time when EV manufacturers are already having a difficult time extending the actual range of their vehicles.
While sound does alert those nearby, it also contributes to noise pollution over time. Additionally, these standards are being implemented at a time when producers like Hyundai have mastered the skill of producing almost silent IC engines.
Following the implementation of these guidelines, EV manufacturers are anticipated to add primary transmissions with helical gear pairs to their product lines in order to make a whining sound. Two-wheeler manufacturers Harley Davidson and Triumph now use a similar approach in their EV powertrains to provide natural sound. But in the end, all forms of sound energy deplete something else, in this case battery charge.
