HEAD acoustics Launches Acoustic Environment for Realistic Noise and Reverberation Measurements

Users of mobile phones, voice-operated smart home devices or hands-free terminals have to deal with different background noises and room reverberation that impair their user experience. Therefore, realistic performance tests of communication devices do not only need to consider background noise but also reverberation. HEAD acoustics launches 3PASS reverb for this purpose, a software option for its background noise simulation systems 3PASS lab and 3PASS flex.

Accusonus Releases ERA-Bundle Single-Knob Plugins for Audio Repair

We have witnessed the evolution of digital processing algorithms getting so sophisticated that it actually becomes possible to "fix in post" those audio recordings that feature common problems such as background noises, excessive reverb, and voice sibilants and plosives. Many existing processing and audio repair packages feature a world of possibilities to handle such problems, but sometimes users simple need to get "things done," quickly. That's what software company Accusonus proposes, with the ERA-bundle of single-knob plugins.

Time Synchronous Averaging

July 26, 2015 by Christopher J. Struck

Time Synchronous Averaging

When performing electroacoustical response measurements, an important practical consideration is the reduction of uncorrelated background noise. Synchronous averaging (i.e., “complex averaging,” “time domain averaging,” or “vector averaging”) is a technique originally developed to analyze the vibration signature or rotating machines and gearboxes. It can be used to improve the S/N ratio measurement. This article was published originally in Voice Coil November 2012.
