Hear more easily, even when it's noisy

Every day you're constantly moving through different environments — and your sound processor should adapt to all of them automatically.

Cochlear™ Baha® 5 sound processors feature advanced technology to help you hear your best, whether you're out on a windy day, in a busy playground or rushing through an airport.

Baha 5 Sound Processor features include:

  • 17 channel sound analysis

  • scene classifier

  • active directionality

  • active gain

  • noise and feedback management systems

  • data logging.

Excellent sound quality

The Baha system lets you experience clearer sound with less risk of annoying squeaks and squeals.

It does this by combining feedback management with a transducer that produces less distortion than other bone conduction systems.1

"I feel comfortable as a parent knowing that whatever environment he walks into, his sound processors adapt."

- Emily, mother of Josh, Cochlear™ Baha® recipient, USA

Sound processors that adapt to your world — automatically

We designed our SmartSound® iQ technology to replicate natural hearing. It automatically adapts to your environment without the need to make manual adjustments.

How it works:

  • Analyses your surroundings and identifies the listening environment as one of seven scenes, such as quiet, noisy or windy.

  • Sound is adjusted automatically for your environment with SmartSound iQ technology to deliver your best hearing.

  • Enhances speech to help you hear what’s being said and tunes down background noise so you can confidently join the conversation.

Data logging provides important information to your hearing health professional

Life is busy. Some days it's tough to remember the details of how you're using your sound processor.

That's why Baha 5 sound processors feature data logging technology that records detailed information about how you use them.

Data logging gives your hearing care professional evidence to show how the system is working for you. They will use this information to make decisions about how to adjust your device to make sure your hearing is always at its best.

Peace of mind for parents

The data logging function gives you added confidence that your child is hearing their best at all times.

The information allows your hearing care professional to know how your child is using the system.

This includes the number of hours per day the sound processor is on, the different sound environments your child experiences throughout the day and the volume levels that were in use.
