Noise Control/Binaural Spatial Mapping

Noise Control prioritizes speech in noise by making discrete adjustments per memory to Voice iQ²/Voice iQ/Noise, AudioScapes, and InVision Directionality. Voice iQ²/Voice iQ/Noise reduces noise and preserves speech to improve the patient's experience in noise. Its fast-acting algorithm is active 100% of the time to reduce the effects of noise even between the pauses and syllables of speech. AudioScapes enhance comfort in a variety of challenging environments (Quiet, Wind, and Machine Noise) by incorporating slow-acting noise reduction strategies. InVision Directionality improves speech understanding in noisy situations through the use of state-of-the art directional microphone technology. The activity level and directionality (Omni, Directional, and Dynamic) settings can be selected independently per memory environment. Any adjustments can be demonstrated live to the patient by simply talking or playing an audio file via Media Player. Noise Control is only available for Advance 26, Advance 26 Micro, Advance 24, Advance 25, and Advance 23 products.

Binaural Spatial Mapping enhances sound quality and reduces listening effort by automatically adjusting synced wireless hearing aids to facilitate the best signal-to-noise ratio (SNR) and comfort in any listening situation. InVision Directionality (Dynamic Directionality) facilitates an optimal signal-to-noise ratio when speech is present and AudioScapes (Wind and Machine Noise) enhance comfort when noise is present but speech is absent. Binaural Spatial Mapping is available on all wireless products except Advance i426, i326, 524, 424, and 324.

Binaural Spatial Mapping is automatically enabled for all environments and memories. InVision Directionality (Dynamic Directionality) is not available for Telephone memories or memories that employ a fixed directional (e.g., Restaurant/Party) or omni-directional (e.g., Theatre/Distance) microphone strategy. If Binaural Processing Off is selected for any memory, this feature is not available and "N/A" displays. The environment selected for each memory displays in a tool tip by pointing to any memory tab.

In order for the ear-to-ear feature to function within a specific environment and memory, the adaptive feature must be enabled in the memory for both hearing aids. In addition, Binaural Spatial Mapping can only be enabled within the specific environment and memory when the activity level for each hearing aid is 1 or greater. The activity level within the specific environment and memory can be different per ear side as long as neither side is set to 0.

This feature is available on all wireless products except Advance i526, i426, i326, 524, 424, 324, and Advance Micro i526. If selected, which is checked by default, communication between the left and right hearing aids improves patient comfort in wind noise by ensuring that both devices make coordinated changes in response to the sound environment.
    Machine Noise Binaural Spatial Mapping Denotes whether or not to automatically enhance comfort when machine noise is present but speech is absent for all memories. This feature is available on all wireless products except Advance i526, i426, i326, 524, 424, 324, and Advance Micro i526. If selected, which is checked by default, binaural communication between the hearing aids provides more symmetrical noise reduction and increases patient comfort in environments with machine noise.
    Directionality 
    Binaural Spatial Mapping
    Denotes whether or not to automatically facilitate an optimal signal-to-noise ratio when speech is present for all memories. This feature is available on all wireless products except Advance i426, i326, 524, 424, and 324. If selected, which is checked by default, wireless communication between the right and left hearing aids improves the ability of the directional system to adapt to changes in the listening environment and to ensure that speech signals are always preserved binaurally. The system detects the direction of the signal source, compares the SNR between the right and left ears, and chooses the side with the better SNR to determine the directional focus for the hearing aids. If no speech is detected, the system adapts to provide the most comfortable listening setting.
