Production lines without and with EQset

A day without EQset versus one with EQset™

There are many factors involved with running a production line that can affect its efficiency. Some of them are controllable and others are just facts of life.  Calibration (particularly calibration frequency) is one area that can be adjusted and have a considerable impact on the performance of the line. Of course, there is a trade-off. The trade-off for traditional microphones on a production line is increased uncertainty. Reduced calibration is more uptime on the line, but it results in an increase of good units being tagged bad and bad units making their way into the market, damaging customer satisfaction and adding the expense of returned products. Another option is a microphone that is stable and accurate without frequent calibration.


Pass-fail windows, uncertainty, false passes, and false failures

Pass-fail windows

On a production line, the devices under test (DUTs) have a set of specifications from R&D or the customer that they must comply with. This can be viewed as a window on a graph.
