Patented & Radically Better

Technology Advantages

Suppresses both repetitive sounds (such as plane engine noise) and dynamic sounds (like the baby crying in the row behind you) by 50% or more, across the full range of human hearing and beyond, with nearly no latency (less than 1 millionth of a second), using very little processing power. Over 10x the effective frequency range of the commonly used X-LMS Adaptive Filter technology (aka ANC or Automatic Noise Cancelling).

Product Benefit Examples:

Mobile Phone: Hear and Be Heard, wherever you are.

Headphones/Earbuds: Quiet the crying babies and engine noise. A lighter & more comfortable product.

Virtual Assistants: Will understand you better. Will “hear” you over the music you asked it to play. Won’t “self-wake” when a commercial says its name.

Laptops/Tablets/Webcams: Never hear “please mute” on a conference call again. Keep your home life out of your home office.

VR/AR/Gaming: Eliminates the “Broadcast Echo” which happens when a user is not wearing a headset.

Air Conditioning Systems & Appliances: Quieter living and working environments.

Vehicle Cabins: Quieter with lower materials cost.

Military: Improved communications, surveillance and stealth.

How is Silencer Devices Radically Better than other technology?

X-LMS Adaptive Filters:

• Commonly used in headphones & earbuds. Often referred to as “ANC” (automatic noise cancelling)

• Effective on repetitive/cyclical sounds, but not on dynamic sounds

• Effective on lower frequencies between 60Hz – 2500Hz (fails where the ear is most sensitive)

AI-Assisted Finite Impulse Response Filters:

• Used in Microsoft Teams “High” noise reduction setting, which warns you it is a processing power / bandwidth hog

• Can suppress high frequencies, repetitive & dynamic sounds

• Requires significant processing power, time, and energy

Silencer Devices Technology:

• Creates the exact anti-noise required for the application, across the spectrum, in real time (~ 0.0000052s latency)

• Suppresses repetitive & dynamic sounds of any frequency, using very little processing power and energy

• Accomplishes all of the above by effectively pre-calculating the solution to the anti-noise equations

Silencer Devices was formed to help make the world a quieter place, so we can live at our best with less stress. Initially, we spent considerable time and resources trying to use and meaningfully improve upon the legacy LMS Filter-based noise cancelling technology commonly used in headsets, headphones, true wireless earbuds, etc. As you may know, LMS technology was initially commercialized in the 1980’s and, as we came to realize, in practice, it is not effective on frequencies above 2500 Hz or on dynamic sounds like music or people talking.

Since AI-based systems require significant processing resources, they are currently impractical for portable devices, and the processing time required limits their ability to suppress sounds in real time for your real life needs. Therefore, we did not pursue that path.

Frankly, we were about to give up just before we envisioned our new approach, which is effective across the Audio Spectrum and beyond, and can handle both repetitive and dynamic sounds. This means that Silencer Devices technology works on the airplane engine noise and the crying baby. In addition, our patented technology was developed with cost of deployment in mind. Clearly, we have created a Radically Better Electronic Noise Cancelling Technology.
