Benefits of Delta
Improved user acceptance
Delta's Receiver-In-The-Ear technology (RITE*) places the speaker directly in the ear and the amplifier behind it, for maximum user acceptance.
Clear, comfortable sound quality
Delta delivers a smoother, less distorted sound than thin tube BTE solutions because it avoids the problem of tube resonance.
Frequency response from Delta compared with a typical "thin tube" solution showing the improved sound quality by placing the receiver in the ear canal. The typical tube resonance occurring at 2500, 3500 and 4500Hz is avoided, thereby improving sound quality.
Superior directionality
The triangular shape of Delta enables a 9mm intermicrophone spacing to be achieved in a horizontal plane for greater directional efficiency. This gives Delta far superior directionality in the 2K to 8KHz region. There are also many situations where hearing instruments should not be in directional mode. Delta uses an automatic, multiband adaptive directional system to continuously select the sound processing that gives the best speech to noise ratio for any listening situation, and is capable of reducing several competing noise sources simultaneously.
Noise Management
Working in synergy with the directional system is Delta’s ‘always active’ noise management system. In noisy situations, Delta applies narrow band noise reduction in order to improve listener comfort. In the presence of speech in noise, Delta 8000 uses its patented VoiceFinder™ technology to ensure that noise reduction is optimally applied to speech sensitive frequency bands. In short, Delta delivers the comfort of a narrow band noise reduction system without reducing speech intelligibility.
Artificial Intelligence
The key to making Delta’s noise reduction, compression and directional systems work together in harmony is Delta’s unique Artificial Intelligence enabled system. This system is programmed to continuously optimize the Voice to Noise ratio of Delta so that it instantly and seamlessly changes Delta’s settings. In this way, Delta delivers the best possible combination of sound quality, speech understanding and comfort in all situations.
