Rub&Buzz Test with 100% correlation to the ear
Customers can enjoy fast and reliable Rub&Buzz test results even in noisy factory environments. The typical Rub&Buzz test time is less than one second (< 1.0 sec.).
The patented PureSoundTM technology is a revolutionary new approach for perceptual audio testing. The algorithms model the human ear as a transient analyzer, effectively measuring every audible manufacturing imperfection with an unmatched correlation to the acuity of “Golden Ears” – “you measure what you hear”.
PureSound^TM detects the even subtle manufacturing flaws of speakers or transducers enabling the automatic qualification of the nature of these defects.
Hundreds of systems around the globe are in day to day operation, benchmarking against the best human golden ears performance. PureSound^TM repeatedly provides consistent, objective test results with a 100% correlation to the human ear.
