I wrote a whitepaper looking at the principles of digital signal processing, algorithms,and software that improve hearing for people with hearing loss. This article is intended as an introduction. The complete whitepaper is available for download. The inspiration for this whitepaper comes from the World Health Organization's recent World Report on Hearing (WHO), which shows that 1.5 billion people worldwide have some degree of hearing loss and 430 million people need rehabilitation services. Shockingly, less than 3% (on average worldwide) use hearing aids.

Imagine Marketing, the parent company of boAt a leading consumer electronics brand in India, announced a collaboration with Dirac to include digital audio optimization solutions from the Swedish digital audio processing company in its next-generation audio range of products. boAt currently ranks #1 among the wireless hearables brands in India in terms of volume since 2019. Imagine recently established a 50/50 joint venture with Dixon to expand manufacturing in India.

7 Sensing Software, a company working in advanced embedded audio DSP and machine learning solutions, announced that it has entered into a collaboration with Analog Devices, Inc. The two companies are working together to incorporate 7 Sensing’s state-of-the-art audio solutions for wireless earbuds and headsets embedded into Analog Devices’ recently expanded family of low power codecs. 7 Sensing's Pure Voice solution and Hearing Augmentation suite will expand Analog Device's hardware platform with a valuable, differentiated feature set for manufacturers and brands.

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.
