Bluetooth LE Benefits for Hearing Aids

Bluetooth Wireless Hearing Aids

Bluetooth technology is a wireless communication standard which allows various electronic devices to connect and exchange data over short distances. The technology uses radio waves set to a high frequency to transmit data without interference or security risks. A wide variety of products incorporating Bluetooth connectivity have been developed, including mobile phones, music players, computers, tablets, cars and televisions. When Bluetooth is incorporated into hearing aids, it offers substantial benefits.

What is Bluetooth Classic?

Originally there was no Bluetooth Classic or Bluetooth Low Energy – it was simply Bluetooth, a protocol that we now refer to as Bluetooth Classic since the introduction of Bluetooth Low Energy.

Bluetooth Classic facilitates short-range wireless communication between devices, operating in the 2.4 GHz industrial, scientific, and medical band and allows devices like smartphones, computers, headphones, and countless other electronics to exchange data over short distances without the need for wires.

What is Bluetooth LE?

Bluetooth LE (Low Energy) is fundamentally different from Bluetooth Classic in that it reduces power consumption and cost while maintaining a similar communication range.

Bluetooth LE (Low Energy) is designed to provide significantly reduced power consumption, making it perfect for hearing aids to operate for extended periods without frequent recharging.

Key Benefits of Bluetooth LE

Energy Efficiency: The main advantage of Bluetooth LE is its ability to maintain a long battery life for connected devices, which is crucial for hearing aids and other devices, such as wearables, health trackers, and IoT devices.
Cost-Effective: Since Bluetooth LE requires less power, the overall cost of running devices is lower. It can also contribute to lower manufacturing costs.
Extended Range: Bluetooth LE typically offers a greater range than classic Bluetooth, making it suitable for applications that require longer distances.
Versatility: Bluetooth LE supports a wide range of hearing aids, devices and applications..
Interoperability: Bluetooth LE maintains compatibility with existing Bluetooth devices and systems, ensuring seamless integration and communication.
Speed: Although optimised for energy efficiency, Bluetooth LE offers sufficient speed for today's hearing aids and applications.
Security: Bluetooth LE incorporates robust security features to protect data transmission, which is vital for sensitive applications like health monitoring.

Bluetooth LE is paving the way for a new generation of connected hearing aids and devices that are smarter, more efficient, and increasingly integrated into our daily lives.

Comparison: Bluetooth Classic vs Bluetooth LE

Feature	Bluetooth Classic	Bluetooth LE
Energy Efficiency	Higher power consumption, not suitable for devices needing long battery life.	Optimised for low power consumption, ideal for battery-powered devices.
Data Rate	Higher data rates (up to 3 Mbps) suitable for audio streaming and file transfers.	Lower data rates (up to 1 Mbps), suitable for transmitting small amounts of data.
Range	Typically up to 100 meters in ideal conditions.	Can offer similar or greater range, depending on implementation and environment.
Connection Setup	Slower connection setup, takes more time to establish a connection.	Faster connection setup, allowing quick data exchange with minimal delay.
Cost	Generally higher due to more complex hardware and higher power requirements.	Generally lower due to simpler hardware and lower power requirements.
Compatibility	Widely compatible with existing devices; backwards compatible.	Compatible with newer devices that support Bluetooth LE; interoperability is maintained.
Security	Robust security features including encryption and secure pairing.	Equally strong security with similar encryption and secure pairing mechanisms.
Audio Quality	Supports high-quality audio transmission.	Suitable for high-quality audio streaming but with lower data rate.

Bluetooth Classic is often chosen for applications requiring higher data rates, like headphones and speakers. On the other hand, Bluetooth LE is the go-to for energy-efficient devices that need to operate on small batteries for long periods, such as hearing aids, fitness trackers and smart home sensors.
