How does it work?
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
Can NoiseQC be integrated with PLC or MES systems?
April 28, 2025 stladmin No comments
Yes. The system supports digital I/O and network communication, allowing seamless integration with PLCs, MES, or custom software.
Is data from each test stored for traceability?
April 28, 2025 stladmin No comments
Yes. All test results can be logged with time stamps and classifications. Reports can be exported for QA audits and batch tracking.
Can I use multiple microphones or test stations?
April 28, 2025 stladmin No comments
Yes. NoiseQC can support multi-channel setups and simultaneous testing across different stations in your line.
Does NoiseQC require manual listening or expert tuning?
April 28, 2025 stladmin No comments
No. The system is automated and repeatable, eliminating subjective human judgment. Thresholds can be tuned by non-experts with minimal training.
Is the system suitable for high-speed production lines?
April 28, 2025 stladmin No comments
Yes. NoiseQC performs real-time analysis with decision times under 2 seconds, making it suitable for high-throughput environments.
How does NoiseQC know if a sound is ‘good’ or ‘bad’?
April 28, 2025 stladmin No comments
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.
Can NoiseQC detect subtle acoustic defects like buzzing or rattling?
April 28, 2025 stladmin No comments
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.
What types of products can be tested with NoiseQC?
April 28, 2025 stladmin No comments
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.
Can NoiseQC perform measurements on a sample with 2 engines ?
June 28, 2016 stladmin No comments
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…
Can we measure multiple RPM’s on 1 sample?
June 28, 2016 admin No comments
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.
Should I use sound or vibration measurements to improve my QC process?
February 19, 2016 admin No comments
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.
How to improve the Quality Control in my production line?
February 19, 2016 admin No comments
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…
Can we use multiple tests on each sample ?
November 21, 2018 admin No comments
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.
