This sequence demonstrates how SC20’s new enhanced Perceptual Rub & Buzz algorithm compares to normalized Rub & Buzz and subjective listening. Running this sequence on a batch of good and bad buzzing loudspeakers should help identify by measurement, audibly defective units and where to set production limits. Starting the sequence, the user is asked at […]
This sequence is an example of the many types of tests that can be performed quickly and simultaneously on a loudspeaker production line. It includes perceptual distortion measurement with the new enhanced Perceptual Rub & Buzz algorithm. A stepped sine sweep (StweepTM) from 20 kHz to 50 Hz is played through the speaker and measured […]
Come and see us at ALTI Expo 2022 in Las Vegas, June 5-6. We’ll be exhibiting SoundCheck 20, the latest release of our popular audio measurement software, as well as AmpConnect 621, our new multichannel hardware interface. Company founder and president, Steve Temme will present a paper on our new enhanced Perceptual Rub & Buzz […]
We’ll be attending and exhibiting at the AES International Automotive Conference in Detroit, June 8-10. Stop by and visit our booth to learn more about the latest version of SoundCheck, including a host of new features designed for multichannel and communications testing, as well as the new enhanced perceptual Rub & Buzz algorithm. Listen founder […]
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 […]
May 18th 2022. 10am (China Time) / 2022年5月18日上午10点（中国时间） In this short seminar, Les Quindipan explores the use of SoundCheck for end-of-line production testing. He discusses typical test configurations and the type of measurements that can be made, how to set pass/fail limits and how to optimize tests for high throughput. He will also explain how […]
Steve Temme discusses the evolution of production line Rub & Buzz measurements in this April 2022 issue of AudioXpress. Starting with simultaneous analysis of higher order harmonics, he explains the progression of improvements including the greater accuracy offered by normalized distortion measurements, and progressing to the introduction of perceptual metrics. He covers the introduction of […]
March 24, 2022. 10:00am China time Listen continues to lead the way in perceptual distortion measurements with our new Enhanced Perceptual Rub & Buzz algorithm. This new product, based on years of original research, offers unrivaled repeatability, reliability and correlation to human hearing, making it an unbeatable solution for end-of-line perceptual audio test. Our launch […]
April 12th, 2022. 9.00am and 2.00pm Eastern US time (6.00am and 11.00am West Coast time) Virtual instruments, included in SoundCheck, are a cost-effective and portable software-based alternative to hardware instrumentation, ideal for making quick measurements or viewing device behavior in real time. In this educational seminar, Les Quindipan walks through a demonstration of the virtual […]
This sequence is used to measure the NRR, or Noise Reduction Rating, of a hearing protection device to the ANSI S3.19-1974 standard. NRR is a numerical representation of the sound attenuation of a device. The sequence first measures the response spectrum of the unoccluded hearing protector test fixture, then makes a second measurement with the […]
