 Tyre Cavity Microphone (TCM)
Wind Noise Microphone

The TCM is a remote controlled radio microphone designed to capture the noise inside the tyre's cavity.

TCM250The TCM comprises two small curved aluminum modules, interconnecting cable, radio receiver with integral antenna, magnetic antenna with 5 meter cable, for in-vehicle recording.
The two aluminum modules are tensioned against the wheel hub by a stainless steel harness. The modules are connected by a multicore umbilical cable that includes the antenna.

The TMC is controlled by a radio key fob. On standby the TCM battery last 7 days and when transmitting continuously 8 hours. It can be turned off between recordings to allow recording over several days.

The Radio receiver, with BNC socket, provides an output signal suitable for analysis and recording systems.

The radio ling range is dependent on wheel and body screening but is typically >10 meters.



Bay Systems Wind Noise Microphone


An accurate and cost effective solution for the measurement of wind/turbulent flow induced noise

The Bay Systems Wind Noise Microphone is supplied with all signal conditioning needed to allow the signal to be recorded using a standard ADC system. The data presented in this technical note was collected using the BAY Acquisition and Reporting System (BARS) which is a 24bit ADC with a choice of +/-1v and +/-10volt range and IEPE power. The input range used for this
work was +/-10v. The typical frequency response of the BAY WNM is flat to better than +/- 3dB
from 80Hz-8kHz.
