Phonak Audéo Infinio Ultra Sphere I70-R

Advanced AI hearing for confident speech clarity in noise

The Phonak Audéo Infinio Ultra Sphere I70-R is a powerful rechargeable hearing aid designed for people who want exceptional speech clarity in noise, without needing every top-tier feature.

It shares the same core platform as the premium I90 model, including Phonak’s advanced dual-chip architecture and AI-driven speech processing, delivering outstanding real-world performance at a more accessible level.

At the heart of the Ultra Sphere I70-R is Phonak’s innovative dual-processor system. One processor manages everyday sound quality, efficiency and wireless connectivity, while a dedicated AI sound-processing chip works continuously to separate speech from background noise in real time. This allows voices to remain clear and stable, even in busy environments with multiple speakers.

The latest AutoSense™ operating system automatically analyses your surroundings and adapts seamlessly as environments change. Whether you are in conversation at home, in a café, at work, or outdoors, the hearing aids adjust automatically to balance speech clarity, comfort and environmental awareness — without manual adjustments.

The Ultra Sphere I70-R provides excellent all-day battery performance on a single charge, even with regular audio streaming and advanced processing active. Rechargeable convenience means no disposable batteries, with simple charging at home or on the go

Connectivity is fast, stable and universal. The I70-R supports hands-free phone calls and audio streaming from smartphones, tablets and computers, with the ability to pair multiple Bluetooth devices and switch between them smoothly. Built-in support for future Bluetooth audio broadcasts and remote microphone systems further enhances hearing performance in challenging listening situations.

The hearing aids are also designed for real-world durability. Improved protection against moisture, sweat and dust helps ensure reliable performance day after day, whether you are active, outdoors, or caught in changing weather.

How the I70-R differs from the I90-R

The Ultra Sphere I70-R delivers the same core AI speech separation and sound quality as the I90-R, but with fewer advanced automation layers and fine-tuning features. The I90-R offers additional enhancement options for the most extreme listening situations, while the I70-R focuses on the features that provide the greatest everyday benefit for most users.

For many people, the I70-R represents the ideal balance — premium technology, excellent speech understanding in noise, and outstanding value.

Highly Water Resistant and “Life Proof”

Of real significance is the superior water resistance provided by Phonak Audeo Infinio hearing aids. They have multiple layers of moisture, dust and dirt protection affording them an Ingress Protection Rating that exceeds the industry average of iP68. Whether you’re caught in a rain shower or exposed to dust, these hearing aids are engineered to perform reliably in various environmental conditions.

The exterior has a hydrophobic coating which causes water and moisture to instantly bead and slide off. The microphone inlets and ports have been redesigned into a labyrinth layout so moisture has little chance of reaching the microphones.
In the unlikely event that any moisture enters the shell of the hearing aid, all the internal electronics and the lithium ion rechargeable battery are completely sealed away by a Parylene coating. There is little to no chance of corrosion even if moisture enters the hearing aid.

Parylene conformal coating is a thin film coating technology used to improve the capabilities of leading-edge technologies. It is applied as vapour and the coating layer perfectly conforms to complex shapes and provides complete and even coverage.

Product designers use Parylene to waterproof electronics, add dry lubricity or enhance adhesion to other coatings. Parylene coatings are a popular choice in applications where reliability and performance matter most. It has become the protective coating of choice for industrial and consumer electronics, aerospace and medical applications.

Reliability testing has successfully included prolonged immersions in salt water, chlorinated pool water, fresh water. So they are truly “Life Proof”. Although it is still not recommended that you swim whilst wearing your hearing aids as there’s a chance of them being lost. Also the receivers that although readily replaceable aren’t quite as water resistant and the main body of the RIC style hearing aid.

Highly Durable Phonak Infinio

To ensure robustness and reliability ,Phonak Infinio’s development has also included over 10,000 hours and 135 individual rigorous mechanical tests. From impact ressiatnce to button reliability tests.

Amazing Technologies Working in Concert

For over 75 years, Phonak has been committed to addressing the number one concern for people living with hearing loss and that is to improve their ability to understand speech in noise. The ability to understand in noise is one of the most important predictors for hearing aid satisfaction.

Adaptive Directional Microphone Technology:

A well established way to improve speech understanding in noise is the use of adaptive directional microphone systems. Where two or more microphones work together to prioritise input from a specific directional and can adapt the focal patterns (polar patterns) to focus on the speech sound and steer away from dominant noise sources. Phonak introduced StereoZoom in 2012 which used the input from the pair of microphones on the left hearing aid and compared and coordinated the inputs from the right hearing aid in real time to create a virtual 8 microphone network with create a super directional or “beam forming” focus on the target speech signal. This substantially improved signal to noise ratio SNR

StereoZoom 2.0 was introduced in 2022 with Phonak Lumity which was deigned to balance spatial awareness at lower levels with speech focus at higher levels of competing noise. The strength of Stereozoom 2.0 is adapted to the environment based on noise level.

AutoSense OS 6.0 in Phonak Audeo Sphere Infinio hearing aids will continue to identify challenging acoustic environments and automatically transition into Spheric Speech in the loud noise program. Spheric Speech in Loud Noise being a unique combination of directional microphone technology and Spheric Speech Clarity.

Spherical Speech Clarity

Phonak claims that theirs is the first hearing aid technology to fully exploit an AI systems ability to separate speech from noise.

Spherical Speech Clarity is an AI based solution designed to differentiate the desired speech signal from unwanted noise, effectively removing undesirable sound while maintaining the speech signal in real-time. This improves Signal-To-Noise Ratio by up tot 10dB which effectively doubles the ability to follow speech in competing noise.

This process is powered by Phonak’s Deep Spheric Optimised Neural Integrated Chip (DEEPSONIC™) and the Audio Quality Estimator DNN.

Steps in Signal Processing:

Sound Scene Classification: Signal processing starts with AutoSense 6.0 analysing the sound scene to determine the type of processing required to maximise user benefit within the specific context.
Following sound scene classification hearing aid microphones are adjusted to restore a degree of spatial awareness.
In the next Step Spheric Speech Clarity identifies and removes unwanted noise from the audio signal, retaining only speech sound. This is the work of the Deep Neural Network (DNN) that was trained with 4.5 million parameters and 22 million sound samples for this purpose. The DNN computes a 64 frequency mask that separates speech from noise and then applies it to the audio signal.

What is a Deep Neural Network (DNN)

Describing electronic computational systems as neural networks is an analogy. Calculations in artificial neural networks although related are not the same as the ones that occur in biological brains. A single layer in a Neural Network (NN) is built from simple operations of largely addition and multiplications. With Inputs and parameters that affect outputs. In the case of Phonak’s Spheric Speech Clarity the Input is the full sound spectrogram containing 64 frequencies and phases, so there can be from x1 to x128.

A Deep Neural Network (DNN) is built from chaining multiple layers of calculations together. So, DNN’s are complex computational models that simulate the way the human brain processes information. DNN’s allows vast amounts of parallel computation to occur which allow them to detect complex patterns in sound, make predictions, and solve tasks.

Training a Deep Neural Network

Training the Deep Neural Network involved the use of an Audio Quality Estimator taken from a huge sample of human perception based preferred audio quality. Approximately 350 humans rated the noise, sound quality and overall preference of 30,000 sound files resulting in nearly a million human ratings. These audio files rated on:

How much noise does it contain?
How Good is the overall sound quality? Are there any distortions?
Overall, How much do people like how it sounds?

The result is a DNN that can predict human ratings on any piece of audio data. This contributes to the optimum balance of speech clarity and sound quality in any acoustic environment.

Results of a Field Study

A fixed directional microphone setting combined with noise cancelling algorithms like Phonak Noise Block and Dynamic Noise Cancelling (DNC) creates a signal to noise ratio improvement of 5.1dB. These features then combined with SteroZoom 2.0 increases this improved SNR to 6.4dB.

Spherical Speech Clarity combined with StereoZoom narrow microphone directionality creates an unprecedented SNR improvement of 9dB at default strength and 10.2dB at maximum strength. The strength of the Spheric Speech Clarity can be adjusted by the hearing care professional or by the user with the MyPhonak App.

Phonak claims “Spheric Speech Clarity is not only Phonak’s best performing technology to date, but it also outperforms three key competitors.” This allows you to focus on what is relevant while having a conversation in a challenging listening environment.
