Title: Edwin Randolph Cole: Innovator in Noise Cancellation Technology

Introduction

Edwin Randolph Cole is a prominent inventor based in Dallas, TX, known for his significant contributions to noise cancellation technology. With a total of 12 patents to his name, Cole has made a remarkable impact in the field of audio engineering.

Latest Patents

One of Cole's latest patents is a method and system for hybrid noise cancellation. This innovative technology involves receiving first microphone signals that represent first sound waves and second microphone signals that represent second sound waves. The system performs analog processing in response to the first microphone signals to estimate noise in the first sound waves, generating first analog signals to cancel some of the estimated noise. Similarly, digital processing is conducted in response to the second microphone signals to estimate noise in the second sound waves, resulting in digital information for noise cancellation. The digital information is then converted into second analog signals, which are combined with the first analog signals to create third analog signals for effective noise cancellation in both sound waves.
