ALMA 2010 Winter Symposium
Las Vegas, January 5-6, 2010

Show Preview: Visit the Listen booth for a demo of SoundCheck ONETM, the new low cost, easy-to-use test system for production line testing of loudspeakers, microspeakers and microphones. Containing hardware, software and a sound card, this system is so simple it takes just a minute to set up and can perform comprehensive tests in less than one second.

Paper Presentation: Steve Temme will be presenting a paper entitled "New Method for Measurement of Rub & Buzz Based on a Perceptual Model"
Abstract: Manufacturing defects in loudspeaker production can often be identified by an increase in Rub & Buzz distortion. This type of distortion is quite noticeable because it contributes an edgy sound to the reproduction and is annoying because it often sounds separate or disembodied from the fundamental signal. The annoyance of Rub & Buzz distortion is tied intimately to human perception of sound and psychoacoustics. To properly implement automated production-line testing of loudspeaker Rub & Buzz defects, one has to model or imitate the hearing process using a sufficiently accurate perceptual model. This paper describes the results of a Rub & Buzz detection system using a simplified perceptual model based on human masking thresholds that yields excellent results

Tutorial Presentation: : Brian Fallon will be presenting a tutorial entitled "Testing Headphone Speakers"
Abstract: Testing the basic parameters of a headphone such as frequency response, distortion, and impedance is basically the same as testing a loudspeaker.  However, because of the different listening environment of headphones and earphones, there are some unique challenges that need to be addressed.  These include coupling and sealing of the device under test, accounting for the response of human ear, and differences between testing for repeatability and testing under real world conditions.  This tutorial will cover solutions to these challenges and will demonstrate several examples of headphone testing.
