Product Research and Development

Almost all products and components contain an element of sound and vibration, even if it is not part of the key offering itself. We expect excellent sound performance from a speaker system and vibration durability in vehicles, but do not always consider how the spin cycle of a washing machine affects the life span of the motor driving it - or that there is more to the hum of a lawnmower than meets the ear.

Spot Testing, Real-Time Analysis and Post-Processing

Manufacturers are often required to conduct some sound and vibration testing. It may be necessary to meet general sound and vibration requirements, to document performance, to conform to internal or external standards or to satisfy customer expectations.

To do this, it is often sufficient to perform generalized testing. This ranges from spot measurements to verify and document noise and vibration, through real time analysis of signals to establish levels and confirm performance, to advanced post-processing of data for development and quality assurance of products.

Ease of Use for Both Experts and Occasional Users

Where sound and vibration is not a key offering of products or where sound and vibration expertise is limited, systems must be simple to set up and use. It must be easy to view the status of the data-acquisition system, such as the health of each channel, and its cables and transducers.

Quick and easy setup, such as input ranging and transducer identification, are also keys to clear, effective testing, as is software that is easy to use and fit for purpose. If requirements are likely to expand over time, scalability also comes into play when selecting a measurement and analysis system.
