ZF unveils chassis based system to cancel tyre noise
Mar 9th 2026
ZF's software driven chassis noise control uses sensor data and tiny damper movements to cancel tyre noise near 200 Hz, promising quieter cabins without heavy insulation or expensive speaker systems.
- ZF's Active Noise Reduction uses a Smart Chassis Sensor with an integrated accelerometer to measure vibrations transmitted from tyres to the cabin.
- An algorithm in ZF's CubiX platform recognises tyre cavity noise around 200 Hz and commands micromovements in semiactive dampers to generate a counter signal.
- The micromovements are too small to affect the dampers primary job of handling vertical suspension motion, so ride and roadholding are unchanged.
- The software based approach removes the need for cabin microphones and speaker based acoustic systems typically found only in luxury cars.
- ZF supplies about 40 percent of semiactive dampers worldwide, so the technology could spread to lower priced cars.
