Oticon Introduces Oticon More Hearing Aid with On-Board Deep Neural Network

Hearing aid manufacturer Oticon is challenging once again the conventions of hearing aid technology and looking at ways to leverage the latest advancements in edge-processing. The company launched Oticon More, the first-ever hearing aid built with an on-board deep neural network (DNN), to give people with mild-to-severe hearing loss a fuller, more balanced and more effortless hearing experience. The goal is to enhance hearing with an AI engine trained on real-life sounds.

German studio specialist Neumann.Berlin introduced the MA 1, an integrated hard/software tool for monitor alignment, acoustic calibration and room correction, tailor-made for Neumann studio monitors. Calibration algorithms, jointly developed with Fraunhofer IIS, the world’s leading institute for audio signal processing, ensure best possible monitoring quality in any environment – from acoustically untreated bedroom studios to professional control rooms.

Following up on the two Communication articles published in audioXpress October 2020, Hans W. Gierlich, from HEAD acoustics GmbH, a top expert in his field, contributed this great overview article. With most company employees working from home and the trend toward decentralized organizations and remote collaborations, where webinar and conferencing services are the new way of communication, this a timely topic.

Synopsys announced that DSP Group selected Synopsys DesignWare ARC EM5D Processor IP for its high-efficiency control and signal processing capabilities to enable development of its DBMC2-TWS advanced adaptive processing audio codec for true wireless stereo (TWS) headsets. To dynamically configure settings and filter parameters on-the-fly, the DBMC2-TWS integrates an ARC EM5D processor, abundant internal memory and numerous digital interfaces.

We probably listen to more music and podcasts in our cars than anywhere else. Which means this is where we’re pushing the boundaries of audio experience — less noise, personalized sound zones, and control. And we’re more aware of the safety implications, not distracting or tiring the driver. This article was published in audioXpress, June 2020.

Is it an understatement to say that echo cancellation has been a kind of “holy grail” ever since the first conference call? Nureva’s patented Microphone Mist technology rethinks that quest in innovative ways. In this article, Erica Yorga shares how the development process of a real-time calibration method for acoustic echo cancellation awarded surprising results.

audioXpress July 2020 is now available, and there's a quiet revolution happening in audio amplification. Essentially it is the direct result of strong innovation in Class-D technology, with incremental improvements introduced on multiple fronts. In this month's Market Update, J. Martins details a few of the "Class-D Products Getting Smarter" and then Stuart Yaniger discusses Class-D amplifiers from two of those companies: Purifi Audio and Orchard Audio. Also, Ward Maas details his visit to Purifi Audio. Dimitri Danyuk shares his "Fully Balanced Transconductance Preamplifier" project, Roger Russell is "Hunting the Elusive Transient," and Ed Simon concludes his "Powering Your Circuits" series. And there's much more valuable content in this edition. Download or view your issue online now.

This article by Hans W. Gierlich and Jan Reimes - two top experts in communication technologies from HEAD acoustics GmbH - details the expanded effort for understanding speech under noisy conditions, and addresses a new approach recently introduced by HEAD acoustics, resulting in a new model that can be used to test active noise cancellation (ANC) performance in complex scenarios where the system needs to distinguish between speech signals as part of the background noise and speech signals directed toward the users of these devices. This article was originally published in audioXpress, April 2020.

Pico Technology announced the further development of its PicoScope 6000E Series oscilloscopes with the launch of three new 4-channel models, each of which can be configured with 16 optional digital channels. With bandwidths of 300 or 500 MHz, 8-bit or 8/10/12-bit Flexible Resolution and up to 4 GS deep capture memory, these products enhance the existing PicoScope 6000E portfolio, adding to the 8-channel models that were introduced earlier in the year.

Sound Devices announced the NoiseAssist Noise Suppression Plugin for their 8-Series mixer-recorders. NoiseAssist is an advanced signal processing algorithm that reduces background noises such as traffic, generators, HVAC noise, and more. The plugin continuously monitors background noise to make sure only clean audio is recorded for the entire take. It features a simple user interface with only one adjustment, the amount of background noise to suppress. The plugin is available now for an introductory price of $600.
