Electronic Listening Tool for Wind or Whistle Noise?

6:21 pm Drivetrain and Noises, noises

Ford-Truck-1940

© DenLorsTools.com Summary: Master auto technician answers questions on how to find the cause of excessive wind noise and the use of the Steelman Chassis Ears. Electronic specialty tools like the wired and wireless versions are designed primarily to find sources of chassis noises.

Question – I have a question regarding: Steelman ChassisEar Squeak / Rattle Finder – Multi Mic Stethoscope. Product #: STE6600 I am looking for a wind whistle in my ’39 Ford pickup. I have been building my own setup to look for it but see that this instrument may be easier to use. My main question is whether or not the microphone cables are shielded? The electromagnetic noise is VERY bad in this old vehicle and tends to mask the whistle I am looking for. Thanks, Scott

Scott, thanks for the inquiry. The ChassisEAR cables for each channel are not shielded. I’m not sure that this would pick up wind noises very well anyway. This kit is best for finding deeper noises like from suspension, steering and drivetrain components. These type of noises are more apt to create a noise or vibration that resonates through the car’s chassis which can be detected by the microphones. In fact here is a list of what the manufacturer says the STE06600 is ideal for.

Wheel Bearings, Fuel Injectors, Brake Calipers,, Alternators, C.V. Joints, Water Pumps, Leaf and Coil Springs, Smog Pumps, Differentials, Power Steering Pumps, Transmissions, AC Compressors, Body Squeaks and Rattles, Industrial equipment and Under the Dash.

Wind Noises

Unfortunately, for wind noises there may be more time involved to find the problem. I’ve had some success in the past by temporarily using blue painters tape around window, windshield and doors for test purposes. Start in one of the suspected areas and see if anything changes when the tape is applied. Sometimes windshield seals look perfectly fine but can vibrate quickly at highway speeds and make high frequency noises.

Sometimes they’re not much fun, but with a methodical approach noises can be pinpointed. Good Luck!
