Hyper-realistic SONET modules
engineered for the sound pollution.

SONET designs products which control the horn system of the vehicles and suppress the horn line until it passes the TX zone. We mainly design TX and RX semiconductor embedded chips to communicate over RF signals.

Why Horn Pollution Matters ?

Understanding the invisible threat

📊
By the Numbers
Noise above 85dB causes permanent hearing damage. City traffic horns regularly exceed 110dB — equivalent to a jackhammer at close range.
🧠
Health Impact
Chronic exposure to horn pollution elevates cortisol, disrupts sleep cycles, and increases cardiovascular risk by up to 20% in urban residents.
🛡️
SONET Solution
Smart acoustic dampening panels analyze, intercept, and cancel horn frequencies in real-time — protecting zones like hospitals, schools, and homes.
🌐
Network Effect
Each SONET unit can cover upto kms and build a network in a metropolitan city.
