Title: Doug Olsen: Innovator in Audio Technology

Introduction

Doug Olsen is a notable inventor based in Mesa, AZ (US), recognized for his contributions to audio technology. He holds 2 patents that focus on enhancing audio experiences, particularly in the context of hearing augmentation and noise reduction.

Latest Patents

One of Doug's latest patents is titled "Ambient-aware background noise reduction for hearing augmentation." This innovative audio system is designed to reduce stationary noise while maintaining dynamic environmental sounds in the received input audio signal. The system incorporates a signal-to-noise ratio (SNR) estimator that calculates both a priori and a posteriori SNRs. A gain function utilizes these estimated SNRs to compute coefficients for a frequency domain noise reduction filter, which processes the input audio signal to produce an output audio signal. The SNR estimator, gain function, and filter work iteratively over multiple frames of the input audio signal, ensuring optimal sound quality.

Another significant patent is "Single-microphone wind detection for audio device." This method detects wind noise affecting a single microphone by analyzing an audio signal indicative of sound incident on it. The process involves dividing the audio signal into several frames and determining the presence of wind noise through a correlation metric and power ratio differences between frequency ranges. This innovative approach enhances the clarity of audio recordings in windy conditions.
