The analysis of noise, vibration, and harshness (NVH) is one of the most demanding disciplines in measurement technology. The goal is to precisely measure unwanted noise, vibrations, and harshness in mechanical systems, identify their causes, and optimize product quality in a targeted manner. While this is highly relevant in mechanical engineering and aerospace, it is currently proving to be a decisive competitive factor in the automotive industry.
New requirements in automotive development
The shift toward electric mobility has fundamentally changed the requirements for NVH analysis. With the internal combustion engine no longer providing a masking background noise, previously unnoticed high-frequency noises, transmission vibrations, and squeak-and-rattle phenomena have come to the forefront. For development engineers and test bench experts, this means: higher measurement accuracy, faster data acquisition, and absolute reliability in signal analysis.
Maximum performance on the test bench: The LTTsmart
To handle these complex measurement tasks, you need hardware capable of capturing even the finest vibrations. This is exactly where the LTTsmart measurement system comes in:
- Highest sampling rates and dynamic range: Seamless acquisition of even transient signals and high-frequency effects.
- Precise synchronization: Perfect coordination of parallel measurement channels for complex NVH investigations.
- Industrial-grade robustness: Ideally suited for long-term use on modern vehicle and component test benches.
With the LTTsmart, engineers and measurement technicians gain the data foundation needed to efficiently analyze acoustic weak points and ensure premium-level ride comfort.
