NoiseCheck

NoiseCheck ‘listens’ to the product and quantifies both the level and frequency of the noise to ensure that they are within pre-set limits. It can simultaneously carry out time-domain analysis for transient noise and frequency domain analysis for steady-state noise, replicating the human ear’s ability to hear both types of noise at once. It offers many advantages over human listeners, such as detailed fault detection analysis, clearly displaying the type and magnitude of the fault, automatic saving of data for later analysis, automated record keeping/part traceability, and can easily be integrated as part of an automated production line. NoiseCheck can also be used in the R&D lab to aid in the design of quiet products.

Operation is simple. The device under test is powered up, either using DC connect, a power supply that integrates with NoiseCheck for automated testing, (for devices requiring a power supply less than 10V DC) or an external source, and Noisecheck records the noise it produces via a microphone. If it is preferable to measure vibration rather than sound, an accelerometer or a laser vibrometer may be used instead of the microphone. For testing run up/down and variable speed products such as some fans, DC Connect can be programmed via NoiseCheck to ramp voltage up/down.
