Oticon Alta2 Pro
Oticon Alta2 is the premium hearing solution family from Oticon. Alta2 is built on Oticon's most advanced technology, and it delivers Oticon's finest listening performance. A range of breakthrough features combine to give you enhanced sound quality and reduce the effort required to listen and understand. In short, Oticon Alta2 is Oticon's best listening experience ever. Oticon Alta2 Pro heads the new line of Inium Sense hearing aids. With the new, even more powerful Inium Sense processor, you are now able to have improved soft speech understanding, tinnitus relief and much more. Ranging from Invisible hearing aids to discreet hearing aids over the ear called the Design range.
Alta2 includes all of Oticon's BrainHearing technologies. These are designed to support your brain and help it make sense of sound with less effort. This makes understanding easier, allowing you to engage fully in conversations and enjoy more of life's situations.
Speech Guard E
All nonlinear hearing instruments change gain as the input level changes. However, the control over the timing of these changes is key. Historically, hearing care professionals have had to choose between slow acting and fast acting systems, invariably making compromises to the quality or clarity of the speech signal.
Traditional approaches to compression can cause some information in the speech signal to get lost or distorted. Speech Guard E controls the dynamic properties of Oticon's multichannel nonlinear hearing instruments, applying gain and compression in a way that is designed to fully preserve the details of the speech waveform.
What makes Speech Guard E unique is the ability to monitor the speech signal in two ways:
Inium Sense provides the power to take these two sets of inputs and drive changes in gain. The goal is to provide stable amplification across the broadest bandwidth possible, yet still respond appropriately to the full, natural dynamic range of the signal in complex environments.
The gain of the instrument is determined by the long-term average of the speech signal in the environment. However, any time there's a change in signal conditions outside the normal dynamic properties of a stable speech signal, the system is temporarily managed by the rapid response gain adjustment system.
Speech Guard E vs. Fast compression
The example below shows how Speech Guard E provides more stable amplification as compared to a fast acting compression system. Speech Guard E adaptive compression system only changes gain when necessary.
Research has shown that Speech Guard E provides better speech understanding, especially in complex listening environments. The better we can preserve the details in the speech waveform, the easier it is for the brain to fully understand the speech signal.
The more easily a patient can identify various distinct sounds in the environment, the easier it is to distinguish between these sounds. They can then choose which one to attend to and which ones to ignore. The auditory system is a binaural system and Spatial Sound is designed to support the natural localization process.
Some manufacturers have chosen to use communication between instruments to create an artificial, situation specific, narrow directionality mode. In contrast, Oticon uses high speed data sharing to balance the gain and compression response between the two hearing instruments. This allows the instruments to preserve the on-going, ear-to-ear level differences in sound that are so vital to localization.
When the patient's two hearing instruments can exchange large amounts of data very quickly, new signal processing possibilities are opened up. Complex signal processing is only available when using a high speed communication link between instruments and is not feasible using Bluetooth or 2.4 GHz data transmission technologies.
Soft Speech Booster
Optimizing the audibility of soft sounds without over-amplifying other background sounds is a delicate balancing act, because every patient's brain processes soft sounds differently. What sounds soft to one person with hearing loss may seem uncomfortably loud to another. This presents a challenge because soft, high frequency speech sounds are part of about 75% of everyday listening environments, not just quieter, one-on-one communications.
