Videos - Noise, Vibration and Harshness

PicoScope NVH episode 1: An introduction

Presented by Pico Technology: Steve Smith and Frank Massey explain the theory of Noise Vibration and Harshness (NVH), defining NVH and explaining the NVH tools from Pico.

PicoScope NVH episode 2: The theory of NVH

Presented by Pico Technology: Steve Smith and Frank Massey explain the theory of Noise Vibration and Harshness (NVH) and how humans differ in their interpretation of noise and vibration.

PicoScope NVH episode 3: NVH set up

Presented by Pico Technology: Steve Smith and Frank Massey explain their approach when dealing with a customer complaint and how to set up the tools and do the tests.

PicoScope NVH episode 4: Working with NVH

Presented by Pico Technology: Steve Smith and Frank Massey discuss the road test results end how you can use the tools to analyze the different areas.

PicoScope NVH episode 5: NVH Time Domain

Presented by Pico Technology: Steve Smith and Frank Massey discuss typical customer complaints that require a different diagnostic approach, cue "Time Domain".

PicoScope NVH episode 6: NVH noise and sound analysis

Presented by Pico Technology: Steve Smith and Frank Massey talk about using the microphone on Channel D in combination with the accelerometer. They cover the importance of where the microphone is placed and how to analyse the result.

PicoScope NVH episode 7: NVH case studies

Presented by Pico Technology: Steve Smith and Frank Massey talk about Frank's case study, the different techniques used and the results.

PicoDiagnostics NVH Kit

Taken from a series on automotive vibration analyzers. In this episode, the PicoScope NVH Analyzer for independent repair shops, tire stores, and automotive dealerships is shown in operation.

3-axis vibration measurement

Steve Smith talks about our NVH kit and completes a 3-axis vibration measurement.

Review of the PicoDiagnostics NVH kit

Scott Brown, President of diag.net uses the Pico NVH kit to identify a vibration in a Chevrolet S10.  

NVH: Using Multiple Sensor Mode | PicoScope Automotive

In this video we use the Pico NVH Advanced diagnostic kit to locate and diagnose an offending wheel bearing on a Ford Ka. 

Knock Knock (What’s That Noise?)

In this video, Steve Smith investigates a knocking noise, with the help of multiple accelerometers and our NVH software.

Wind noise and water ingress with an automotive oscilloscope and Noise, Vibration and Harshness NVH

In this video, our Automotive guru Steve Smith uses the PicoScope automotive oscilloscope and Pico's NVH kit to test wind noise and water ingress, he describes the use of the function generator in combination with our NVH record feature to find the source of potential wind noises and water leaks.

Find that Rattle!

Diagnosing the source of cabin squeaks and rattles is both time consuming and costly as a result. Trying to reproduce these offending noises may involve multiple road tests with at least 1Technician and a driver, often without success! Using the Pico NVH function generator, the vehicle can be “excited” using a broad range of frequencies generated by the in-car audio system without leaving the workshop. This will leave the Technician free to pursue the source of the rattle which may not be located inside the cabin!

Finding the cause of a cabin vibration with the PicoScope function generator

Steve Smith is showing how he used the function generator in the NVH software to find the cause of a vibration in his car, which had been bothering him for a long time.
