SoundCheck - Fast & Reliable Production Line Test
SoundCheck is perfect for the production line as its advanced algorithms allow fast and repeatable testing even in high noise environments, and it integrates fully with automated production lines. It is more reliable than human listeners, and much simpler and less expensive than ‘rack and stack’ systems. A range of lower budget production line software packages offers the functionality required for a manufacturing environment
at significantly less cost than a full R&D system.
Fast
SoundCheck’s advanced algorithms allow extremely fast testing. For example, SoundCheck can carry out a full transducer analysis in as little as one second — including generating the stimulus, measuring all the necessary parameters, comparing the results to a reference standard, and displaying the result as a simple pass/fail message. Multi-channel software and hardware options enable many system parameters to be measured at once for rapid testing of multi-channel devices (e.g. mixing boards or surround sound systems) and batch testing.
Repeatable
Specially designed filters and analysis algorithms distinguish between test signals and background noise to offer repeatable results in noisy manufacturing environments. In addition to measuring all faults that can be heard by human listeners (Rub & Buzz, loose particles, etc.), SoundCheck can also detect and quantify faults that cannot be heard by the human ear such as reverse polarity.
Easy to Use
Tests can be configured for ‘one-click’ or automated operation that will generate a pass/fail output, and various levels of password protection enable you to control who may access and modify test sequences. To further simplify manufacturing tests, a Chinese language option ensures that your overseas production staff or 3rd party vendors understand the on-screen instructions. This all adds up to a system that offers simple, error-free operation.
No Downtime
The SoundCheck platform virtually eliminates test system downtime as all the hardware components — a PC and a professional audio sound card — are easy to purchase and inexpensive to maintain. Should problems occur, your own staff can to get the line back up and running using standard off-the-shelf parts. Optional remote diagnosis via the Internet enables immediate assistance from a Listen support engineer.
Integrated with your Production Line
SoundCheck is compatible with automation software and communicates with hardware such as barcode systems and PLCs, using RS-232, IEEE-488, Bluetooth, FireWire, USB, and TTL interfaces. SoundCheck can be controlled by other programs through LabVIEW or by any programming language that supports ActiveX commands (VB.NET, C#, C++, Java etc.), so it is fully compatible with most test platforms. All test results can be recorded in SoundCheck or output to other software for full statistical process control. Within
an automated environment, tests can be configured to start when the device under test is in place, and failed devices automatically removed from the production line.
Database and Statistical Capabilities
Tests can be configured for multiple data output options. These may include a comparison to reference standards with a PASS/FAIL indication for the production line operator, customized SoundCheck reports, or writing of complete test results to databases such as Microsoft® Access, SQL or Oracle® for archiving, data-mining or report writing. SoundCheck also features an extensive statistical analysis toolbox which includes Gage R&R, max, min, mean, standard deviation, yield, Cpk, and Best Fit to Average.
