The purpose of these sequences is to test the left and right earphone outputs as well as the microphone input of a USB headset. Because SoundCheck supports both analog and digital interfaces, the headset simply plugs into a computer USB port and configures as a digital channel to be tested like a conventional device. For […]
Visit us at ISEAT China’s leading electroacoustics event, where we’re showcasing our latest products with our local distributor S&V Samford. We’ll be demonstrating SoundCheck 24 – our new release – as well as new products for automotive and headphone testing. SoundCheck 24 contains a host of new features to cut test development time and get […]
This sequence measures single-frequency interference (tonal noise) in the send path of a communication device to ensure compliance with the Microsoft Teams Audio Test Specification (Section 6.6). A calibrated mouth simulator plays an IEEE Male speech stimulus at 94 dBSPL followed by a period of silence, which is recorded through the device under test. The […]
This sequence measures single-frequency interference (tonal noise) in the receive path of a communication device to ensure compliance with the Microsoft Teams Audio Test Specification (Section 6.13). The sequence plays and records a test signal containing digital silence directly through the device under test to detect potential narrow-band impairments caused by internal electrical, fan, or […]
We’re excited to announce the launch of a brand new instructional series Audio Basics. In this series we walk you through the key measurements used to characterize audio transducers, explaining what they are, what they tell us about performance and why they matter. We’ll also look at how each parameter is measured, and how the […]
Last week, industry expert and Listen President Steve Temme presented the latest recommendations for automotive audio measurement and the evolving methods used to evaluate modern in-car infotainment systems at Harman’s North American Headquarters in Novi, Michigan. Recorded ahead of the AES Automotive Conference, the presentation discusses the work of the AES Technical Committee on Automotive […]
I’ve just returned from the AES Automotive Audio Conference in Detroit – an event I always look forward to because it combines two of my favorite passions: cars and audio. With an interesting mix of attendees from automotive OEMs, Tier 1 suppliers, loudspeaker manufacturers, researchers and measurement engineers, it’s a great place to see the […]
Standardized measurement of in-car audio systems remains an ongoing challenge, particularly regarding microphone configuration and placement, test signals, and correlation with perception. Current recommendations from the AES Technical Committee on Automotive Audio (TC-AA) advocate spatial averaging using multi-microphone arrays to improve repeatability. While this method reduces the influence of reflections and standing waves to improve […]
