INSPIRIA™ Ultimate (GA3285) is a premium DSP product with matchless performance, extreme flexibility and distinctive features. With state-of-the-art VOYAGEUR™ digital technology and advanced high-end hearing aid algorithms, Inspiria Ultimate offers outstanding sound quality and versatile functionality.
Inspiria Ultimate features iLog™ Datalogging, automatic Adaptive Directional Microphones (ADM), Advanced Feedback Cancellation (FBC 3.0), Adaptive Noise Reduction (ANR3.1), 16-bands of graphic equalization and superior 20-bit wide bandwidth (up to 16 kHz) sound quality of the Voyageur DSP platform delivering unprecedented sound quality, comfort and audibility to hearing aid wearers.
iLog Datalogging unlocks new capabilities for hearing-aid counselling and fine tuning. iLog increases the efficiency of fitting sessions by enabling focussed communication between the hearing instrument user and the hearing care professional. Two parallel methods of datalogging are used to record both detailed short-term hearing aid state information, as well as long-term statistics. The short-term method records detailed hearing aid usage patterns over a 2-3 week window at 15 minute intervals. iLog simultaneously records:
Battery level
Volume control setting
Program memory selection
Ambient sound level and
Length of time the hearing aid was powered on
The long-term method tracks usage statistics over the life of the hearing aid, recording frequency of use for each program memory and overall lifetime use of the hearing aid (Figure 1).
iLog provides important information to help the hearing care professional increase hearing aid user benefit and satisfaction.
ADM 2.0 is a two-microphone processing scheme for hearing aids. The ADM automatically reduces the level of sound sources originating from behind or from the side of the hearing-aid wearer by adjusting the null in the microphone polar pattern to minimize the noise level at the output of the ADM. The automatic steering of the null provides improved signal to noise ratio. The polar patterns change with the nature and location of the noise sources. The rear mic processing is automatically powered-off when not required to save current and offer extended battery life.
Adaptive Feedback Cancellation ~ AFC 3
AFC 3 estimates the portion of the hearing aid output signal that is due to feedback and adaptively cancels the feedback from the signal path as illustrated in Figure 3 using a LMS-based phase cancellation algorithm.
AFC 3 offers up to 30dB of Added Stable Gain with the use of a 40-tap FIR filter. The Added Stable Gain on AFC 3.2 was benchmarked to be greater than most competitive products, which were measured at the National Research Council, Canada. Furthermore, an innovative approach to entrainment management on the AFC 3.2 enhances the efficacy of the product without injecting any distortions to the signal path and offering imperceptible removal of feedback in most environments while maintaining leading edge adaptation speeds.
Adaptive Noise Reduction ~ ANR 3.1
ANR 3.1 is a pioneering solution that improves hearing in noise with two unique attributes:
Continuous monitoring and adjustment across 128 frequency bands
Advanced psychoacoustic models to eliminate audible noise and reduce the amount of distortion inherent in all gain-adjusting algorithms
Utilizing Voyageur technology, ANR 3.1 offers independent noise reduction in an industry-leading 128 frequency bands. This allows for finer resolution removal of noise from a composite signal while enhancing the speech component with advanced psychoacoustics employed in the algorithm. ANR 3.1 offers a versatile noise reduction scheme with up to 12 dB noise reduction. The perceived speech is maintained with excellent sound quality and utmost hearing comfort for the user.
