The FX100 Audio Analyzer is ideally suited for the acoustic testing of transducers and microphones of mobile phones. The optional Rub and Buzz detection ensures a 100% correlation to the human ear, so making tests by human operators obsolete. It is the first solution that enables the manufacturers to conduct a reliable automated quality test. The system includes phantom power supply for the measuring microphone. The typical test cycle time is < 1 second incl. a patented noise cancellation algorithm that immunizes the measurement process against factory noise.
The audio quality test typically comprises of the following measurements.
- 音圧レベル (SPL)
- Rub & Buzz of transducers
