The Future of Audio Measurements – SoundHub Denmark
Weds May 25th, 8.30-12.30
Presenters: Steve Temme, Listen Inc.; Michael Trolle, VibrAkustik
Join us at SoundHub in Struer for a great day of presentations and discussion on the latest in audio measurement. The presentations will cover a variety of audio test topics including the end of line testing for improved efficiency and yield, measurement in real-world conditions, free-field measurements without a test chamber and more. There will also be consultation time when we are happy to answer your questions or discuss any aspect of audio test. This event is highly relevant for anyone needing to test audio products, both in R&D and production.
8.30-9.00: Check-in, coffee & Welcome by VibrAkustik & Sound Hub Denmark (Michael Trolle and Rie Kold Pripsø)
9.00-9.30: Perceptual distortion measurements
9.30-10.00: Accurate measurement of headphones and hearing assistance devices under real world conditions
10.00-10.30: Coffee and discussion time
10.30-11.00: New features in SoundCheck version 20
11.00-11.30: Free-field speaker measurements without an anechoic chamber
11.30-12.30: Consultation time: Bring us your audio devices and your measurement challenges and we’ll discuss your measurement options and demonstrate how your devices can be measured
Note: there will be live demonstrations on all topics, and a display of hardware for a complete measurement chain including fixtures, measurement microphones and sensors, audio interfaces and turntable.
Detailed Content Information
Perceptual Distortion Measurements: Perceptual distortion measurements enable production line yield to be increased by rejecting only devices with audible Rub & Buzz defects rather than any distortion defects, and Listen’s new enhanced Perceptual Rub & Buzz (ePRB) algorithm is the first to perform even better than the human ear! Through proprietary noise reduction technology and advanced perceptual algorithms, its performance in a noisy factory environment is comparable to the performance of a trained listener under normal listening conditions. Learn more about the science behind this algorithm, see the results, and learn how to implement it in your end-of-line tests.
Accurate Headphone Measurements in Real World Conditions: In this demo-focused session, we will demonstrate how to accurately measure Headphones and Hearing Assistance Devices under real world conditions with real world signals such as speech and music. For example, we will demonstrate, in real time, how to adjust the headphone fit for a proper seal on the head and torso simulator and measure headphone ANC with real background noise with our Multi Signal Real Time Analyzer
New Features in SoundCheck: The newly released SoundCheck 20 is at the forefront of audio measurement with new features for multichannel and communications, increasing its capabilities for audio measurement of smart speakers, infotainment systems, headphones and hearables, and other voice-activated and multichannel devices. In this 30 minute session, we will demonstrate the new features and explain how they are used for testing a variety of audio products and applications.
Free-field Speaker Measurements without an anechoic chamber: Can’t afford or get time in an anechoic chamber? That’s not a problem if you have SoundCheck! In this practical session, we will demonstrate a method first developed by Listen president Steve Temme back in 1993, known as the ‘splice’ technique. This measurement technique is easy to configure and enables you to make highly accurate free-field measurements in an ordinary room, avoiding the expense of an anechoic chamber and enabling measurements in your home or office.
