Introducing Enhanced Perceptual Rub & Buzz (ePRB)

The new Enhanced Perceptual Rub & Buzz (ePRB) algorithm increases production line yield by rejecting only those speakers with audible Rub & Buzz defects. It offers excellent correlation with human perception, unmatched repeatability and reliability and is fast, adding no addition time to end of line tests. Watch the launch video to learn more about this ground-breaking perceptual distortion algorithm.

Not all distortion is audible. Perceptual Rub & Buzz measurements identify only those devices with audible Rub & Buzz defects, rather than all Rub & Buzz defects. Basing end-of-line pass/fail decisions on this metric increases yield while maintaining customer satisfaction.

Listen’s new enhanced Perceptual Rub & Buzz algorithm is the first to perform better than the human ear. Its proprietary noise reduction technology and advanced perceptual algorithms make its performance in a noisy factory environment comparable to the performance of a human ear under normal listening conditions. In other words, it is the only perceptual Rub & Buzz metric that accurately correlates real-world end-of-line results with listener perception.

Furthermore, it is highly repeatable, simple to configure and set limits, and can be simultaneously implemented with other end-of-line tests with no increase in overall test time.

Smart Speaker Test Demo

videostill_smart_speaker_test2See how easy it is to test a smart speaker such as the Amazon Echo in this short 4 minute video! We demonstrate how a SoundCheck test sequence can be set up to automatically activate the speaker, play a stimulus, record the response, and measure both the microphone and speaker performance.


Impedance Measurement

In this webinar we demonstrate how impedance can be measured using both highly accurate dual channel methods and simpler single channel methods. The presentation discusses the different test methods and show how each can be set up using SoundCheck. In addition, a novel, patent pending, method of single channel measurement that offers similar accuracy to conventional dual channel methods is presented. Presented by Steve Temme, Listen, Inc.
