Microphones are placed near a device under test. NoiseQC compares its acoustic signature to a reference. If the signature falls outside of tolerance, the product fails.
Details on what kind of comparison is done (time-domain, frequency-domain, both?)
How the reference is created (learned from a golden sample?)
Whether it works on multiple units simultaneously

Yes. The system supports digital I/O and network communication, allowing seamless integration with PLCs, MES, or custom software.

Yes. All test results can be logged with time stamps and classifications. Reports can be exported for QA audits and batch tracking.

Yes. NoiseQC can support multi-channel setups and simultaneous testing across different stations in your line.

No. The system is automated and repeatable, eliminating subjective human judgment. Thresholds can be tuned by non-experts with minimal training.

Yes. NoiseQC performs real-time analysis with decision times under 2 seconds, making it suitable for high-throughput environments.

You can record a “golden sample” or upload a reference file. NoiseQC compares each tested unit to this profile using smart thresholds and Go/No Go logic.

Yes, NoiseQC is designed to identify even subtle issues like buzz, squeak, rattle (BSR), or low-level harmonic noise through frequency and time-based analysis.

NoiseQC is ideal for products with moving parts or noise signatures, such as motors, fans, valves, relays, pumps, or complete assemblies in automotive, electronics, appliances, and tools.

Yes, NoiseQC can be configured to measure the noise / vibrations of a unit with 2 engines, either running simultaneously or consequently. There will be ‘golden egg’ reference spectra for…

NoiseQC has the possibility to create multiple scenario’s for testing. So you could run the NoiseQC test on 1 engine with for example 5 RPM’s. Each setting for the engine where each RPM of course will have it’s own noise or vibration spectrum.

Depending on the local situation it can be better to use either noise or vibration measurements to find faulty products coming from your production line. Sound measurements are good if the ambient sound level around the production line is at least 10 decibel lower than the sound level produced by the device under testing. If the surroundings are too noisy, vibrations can be used to check the quality of each product by means of an accelerometer.

If your products have any moving / rotating parts, it is very easy to check with noise- or vibration measurements. You can measure the noise ‘fingerprint’ or vibration ‘fingerprint’ of…

NoiseQC end of line quality testing software has a build in option to perform up to 6 different tests on each product (i.e. rpm or load), either manually triggered or by PLC.
