With Apple® and Google® removing headphone jacks in the latest smartphones and moving to wireless earbuds, it can be said that wired audio connections will soon become tomorrow's behemoths. Both these consumer electronics giants and leading startups strive Developed for 'real wireless' headsets, the major design challenge they will face is maintaining battery life around the clock, and it is interesting to note that many years ago hearing aids were able to solve this problem and run on a compact battery for 7-10 days.
The main difference between the two is that hearing aids are the first to focus on voice processing to restore sounds that are easy for the wearer to understand, while consumer earbuds are more focused on providing stereo music. As a result, hearing aids typically do not contain a power hungry traditional Bluetooth® radio, Any mobile phone directly receives an audio stream, but it's hard to find a high-end hearing aid with fewer than two radio configurations today: a near-field magnetic induction (NFMI) radio for ear-to-ear transmission of audio and data, Multi-protocol 2.4 GHz radios for field communication. Today's hearing aids use far-field radios that can be coupled to mobile devices via Bluetooth low energy technology and exchange data at modest rates. If the accessory 'uses the same wireless language' (or protocol) They can also transfer audio from remote accessories.Apple smartphones use their own proprietary wireless protocols to connect directly to most high-end hearing aids and deliver the audio to the wearer's ears without intervening devices.These custom protocols All operate on the worldwide available 2.4 GHz radio band, same as the traditional Bluetooth and Bluetooth low energy bands Of course, this connection does have an impact on battery life, but hearing aid wearers need to replace batteries only a few days after enjoying the benefits of these wireless features.
Wireless connectivity brings some exciting new features to hearing aid wearers, allowing for easy remote control of hearing aids with a smartphone, as well as unlimited adjustment and fine tuning.Mobile application developers can take advantage of geolocation and big data And other advanced features for crowdsourcing hearing aids for a given location and acoustic environment.Today, such features already exist in the market, combined with the recent over-the-counter (OTC) legislation in the United States that will not be too long for users to ' Adapt to buy on the shelf of a local pharmacy.
To take full advantage of these features, mobile applications must know how to communicate with hearing aids to adjust many parameters, and today's audiologists need to debug with the new wearer's condition using sophisticated debugging software running on a personal computer (PC) Adjustment) of hearing aids. Now, thanks to the ubiquity of the wireless connection of smartphones, it is easy to imagine that this process can be done remotely even when hearing aid wearers are inconvenient to go face-to-face with audiologists. In addition, The user interface presents a subset of these sophisticated tuning features that allow selected customer groups to self-debug when allowed, an exciting new area where innovation opportunities are ripe.
As part of the Ezairo® Pre-Suite, our Mobile Software Development Kit (SDK) provides middleware for seamless docking of smartphones to hearing aids Developers can now use high-level on iOS® and Android® Application APIs that are the same as they have been used on PC platforms for many years.The combination of ON Semiconductor's Hearing Aid firmware package and a Bluetooth enabled low energy Smartphone together form a complete solution that drives hearing aid manufacturers Into a new era of intelligent, hearing aids.
