Tyre Cavity Microphone (TCM)

The TCM is a remote controlled radio microphone designed to capture the noise inside the tyre’s cavity.
The TCM comprises two small curved aluminium modules.
These are tensioned against the wheel hub by a stainless steel harness and connected by a multi-core cable and antenna.

The TCM will enable engineers to:-

Measure tyre noise accurately
Gather data free from background noise
Develop tyres faster
Select the best tyres for a vehicle
Reduce vehicle interior road noise levels by enabling better road noise route tracking
