Building on 25 years of innovation, Bluetooth® LE Audio enhances the performance of Bluetooth audio, adds standardized support for hearing aids, and introduces Auracast™ broadcast audio, a new capability that will enable an audio source device (e.g., smartphone, tablet, TV, or public sound systems) to broadcast one or more audio streams to an unlimited number of audio sink devices (e.g., earbuds, speakers, hearing aids, etc.). 

Industry experts forecast swift adoption of Auracast™ broadcast audio across a wide range of audio markets.

Recently, Qualcomm released its annual State of Sound report. This report features a summary of research insights based on data from thousands of audio consumers around the world. The State of Sound research looks at audio device purchase drivers as well as interest in current and future use cases to better understand the features that today’s users look for in earbuds, headphones, speakers, and other audio products.

The following is an excerpt from the 2023 State of Sound report that focuses on Auracast™ broadcast audio.

Feature Focus: Bluetooth LE Audio

A new age of Bluetooth® technology is here. With the latest Bluetooth LE Audio specification, the way we experience audio is set to evolve. From Auracast™ broadcast audio and hearing assistance, to new use cases that have not been imagined yet, Bluetooth LE Audio has rekindled innovation in wireless audio and will set the stage for the next 20 years of innovation in the space.

Respondents are interested in a whole range of features that could be enabled by Auracast™ broadcast audio. When asked, “which of the following audio sharing experiences would you be interested in?” respondents were most interested in enhancing their hearing in social/ professional situations, connecting to a choice of screens when at a gym, airport departure boards, cinema screen, restaurant, etc., sharing music/video with friends on their earbuds/ headphones and more.

Hearing Enhancement is an Emerging Use Case for Personal Audio

As the capabilities of audio platforms and technologies evolve—an emerging use case is hearing enhancement to help users communicate and listen more clearly. Hearing enhancement is not only for the hearing impaired; 61% of respondents said they struggle to hear in busy workplaces, lecture halls and meeting rooms. Additionally, 29% are using earbuds to block out background noise.

2023 State of Sound 2

Respondents this year have indicated hearing enhancement is becoming a more important purchase driver, with 24% listing hearing assistance/ enhancement as a key factor they would consider when purchasing their next earbuds. Interestingly, when splitting by age, this demand was higher in the ages 18-44 (27%) category vs. 45-64 (20%)

Consumers are interested in improving their hearing experience with audio devices. 60% of respondents listed hearing personalization (one-time hearing test for personalized audio) as a likely purchase driver for their next earbuds/ headphones. This was highest in China and India, at over 80%.

This year’s responses suggest that hearing enhancement could become more mainstream in the personal audio market in the future, and paired with technologies such as Auracast™ broadcast audio, listeners will benefit from these newer technologies, which will help them engage with the world around them.
