The 'Silent Horn System' is an innovation in the existing automobile horn system, developed by us. It uses IR LEDs and TSOPs to transmit and receive Infrared signals as horn. Buzzers are used produce sound inside vehicles to alert the driver.
The government is also planning to to reducethe noise level of horns on vehicles to under 100 decibels, a reduction of about 10% from the existing maximum permissible limit. As per Central MotorVehicle Rules, the noise range forhorns is currently fixed between 93 decibels (dB) and 112 dB.
Apart from our understanding the honk is usually meant for the driver of the vehicle in front. However, it is heard by everybody in the area, creating noise pollution. with the noiseless horn the sound directly reaches the target with no noise going into the surrounding environment.
