NVH Diagnostics Starter Kit
Starter, Standard or Advanced
The Starter NVH Kit will allow you to measure vibrations on 3 axes, (X, Y and Z).
The Standard NVH Kit gives you the option to also measure vibration or sound on a single axis at an additional location on the vehicle.
The Advanced NVH Kit gives you the option to measure vibration or sound at four different locations on the vehicle.
The Starter to Standard Upgrade Kit gives you an extra set of all the kit items.
All kits are available in a carry case or foam tray. The foam trays enable users to store their NVH Diagnostics kits safely in a tool chest of their own choosing.
NVH - Noise Vibration Harshness problems
The root of all NVH problems is a vibration. In some cases, these are unwanted or unexpected vibrations, and in other cases, they are normal and always present (e.g. engine combustion), but they are noticeably disturbing when transmitted to the passenger compartment.
Sound is simply a vibration that is transmitted through the air (or another medium) and is heard when it reaches a person's ear. Although the perfect hearing range is 20 Hz to 20 kHz, most of us are more like 100 Hz to 15 kHz at best. Vibrations are usually felt at frequencies below 200 Hz, and in the overlapping frequency, range vibrations can be both felt and heard.
In order to deal with this frequency range effectively, our PicoDiagnostics NVH kits contain both microphones (for sound), and accelerometers (for vibrations).
Traditionally, NVH problems have been viewed as difficult to solve, with NVH complaints being subjective as people have different levels of NVH acceptance or feeling. A technician needs the right tools and procedures to be able to tackle these issues effectively, to diagnose complaints in an objective, repeatable and easy manner. The PicoDiagnostics NVH kits do this, while also generating customer reports to show that an improvement has been made against the customer’s complaint.
