Technology Benefits - How it Works

IntelliSonic™ Acoustic Technology
Enhances microphone performance three ways...

Now there is no barrier to your voice-integrated product designs.
IntelliSonic technology brings superior audio clarity to the latest hands-free communication products and applications. When evaluating the different sound conditioning solutions available today, you need to understand the different components and their technical prowess. The Knowles patented array processing, noise suppression and AEC are quite unique.

When more than one microphone is aligned in an array, Knowles' patented algorithm predicates itself upon a time-delay principle to configure an array processor with a predetermined Look Angle and Angle of Acceptance onto the speech source. All acoustic plane waves outside the angle of acceptance are attenuated by greater than 15 dB for a two-element array. Knowles' algorithm can attenuate by greater than 20 dB for a 4-element array.

Within the angle of acceptance the algorithm has controllable adaptive noise filters. Depending upon the anticipated environment, the intended feature (telephony or voice recognition), and the discriminating, subjective nature of the human ear, the parameters of the noise suppression are determined specifically for each application.

In the end, Knowles' IntelliSonic(tm) technology allows a device to attain the SNR levels needed for high-level VR accuracy and clear, concise speech over the bandwidth of telephony or VoIP applications. In short, it allows hands-free usage of the voice applications. It eliminates the need for an ear bud or headset. It is intuitive and natural. It enables multimedia-messaging services and the future voice applications.

Simpler, more affordable audio.
If your product is Windows® based, IntelliSonic software can be loaded. Knowles also provides a complete embedded solution for DSP platforms.

Acoustic Porting
Acoustic porting is the seamless conduction of sound into a microphone for the lowest possible sound loss. Knowles Acoustics designs and manufactures acoustic porting solutions for every microphone we offer. These designs represent our ongoing research into the latest materials for sound sealing and conducting.

IntelliSonic Software
The capture and output of perfect sound is all the more achievable when sound is processed by our IntelliSonic software to eliminate unwanted sound, while enhancing desired sound. The software achieves this through array processing, the suppression of stationary and non-stationary noise, and echo cancellation.

Product Applications

IntelliSonic technology is ideal for mobile phones, PDAs/smart phones, PCs, notebook computers/tablets, video cameras, voice recognition systems and specialty applications (voice-based biometrics, gaming, drive through systems, interactive kiosks, etc.). The software can be installed directly to your application, if your product is Windows® XP based. Knowles can also provide embedded solutions allowing the complete algorithm or subsets to be ported to embedded RTOS'es and DSPs. Please contact us for more information.
