At Listen, we’re at the forefront of audio measurement research, and we’re always looking to improve on existing audio measurement techniques, even our own! Loose Particle detection has been a valuable production metric for analyzing transient distortion since we launched it in 2004. This new iteration uses our own original research to improve accuracy and […]
6月7日 上午10点（中国时间) / June 7th, 10am China time 测试智能设备，如智能音箱、可听设备、手表等，涉及许多不同应用领域的测试组合。从简单的换能器测试到开环测试，蓝牙测量，语音激活测试，电信标准测试，助听器测量等等，不胜枚举。在这个以演示为重点的研讨会上，我们将展示SoundCheck是如何在整个智能设备设计过程中进行所有你需要的测量，从组件选择到预认证测试。 演讲者: Steve Temme, Steve Tatarunis, Mark Latshaw 持续时间：1小时 Testing smart devices such as smart speakers, hearables, watches and more involves a combination of tests from many different application areas.

2023年6月1日 上午10点（中国时间） | June 1st 2023. 10am (China Time) 请参加Listen最新算法–增强型散落粒子（eLP）的发布研讨会。这种新的算法大大改善了生产线的瞬态失真测量，它提供了高精确度，易于与人类感知相关联，并将瞬态失真假象与谐波失真分开识别，便于故障排除。它也是识别音频设备中嘎嘎作响的按钮，以及汽车嗡嗡声、吱吱声和嘎嘎声（BSR）测量的理想选择。这种新的算法是基于原始研究，并使用了以前没有用于失真测量的技术。请参加这个简短的在线研讨会，由Steve Temme先生进行演示，并详细解释这个算法的工作原理。 Join us for a launch seminar for Listen’s latest algorithm, enhanced Loose Particles (eLP). This new algorithm significantly improves production line transient distortion measurement. It offers high accuracy, easy correlation to human perception, and identifies transient distortion artifacts separately from harmonic distortion […]

Active noise cancellation tests are a common headphone measurement. SoundCheck makes these measurements easily, and can even measure the battery drain caused by active noise cancellation. The configuration for active noise cancellation test is similar to a regular headphone test, in that you need a head and torso simulator or alternative headphone test fixture, and […]
For a limited time we are offering deep discounts on a system upgrade to enable you to get up to date with the latest version of SoundCheck. The upgrade offer is a simple flat rate: $4,175 for owners of SoundCheck 15 or 16, $3,402 for owners of version 17, $2,646 for owners of versions 18 […]
Steve Temme discusses the transition from R&D to production testing in this March 2023 issue of AudioXpress. Production line audio testing poses many challenges such as noisy environments, harsh operating conditions, high throughput, relative limits, and more. In this article, Steve Temme shares his observations and outlines the main considerations to ensure a successful operation. […]
It’s easy to make comprehensive audio measurement on Bluetooth Headphones, headsets and hearables with SoundCheck. With the simple addition of a stand-alone Bluetooth interface to your existing test configuration, measurements can be made exactly the same way as your conventional wired headphones. Rather than the test signal being directly transmitted to the headphones via a […]
We have a new automotive test sequence to measure Transient Distortion (also known as buzz, squeak, and rattle, Rub & Buzz, or impulsive distortion), Frequency Response, and Max SPL to the suggested measurement methods set out in the AES Technical Committee on Automotive Audio’s recently published white paper on in-car acoustic measurements. The three measurements […]
