Title: The Innovations of Jeffrey William Sondermeyer
Introduction
Jeffrey William Sondermeyer is an accomplished inventor based in Bothell, Washington. He is known for his innovative contributions to audio technology, particularly in the realm of automatic volume control systems. His work has significantly impacted how audio systems adapt to varying ambient noise levels.
Latest Patents
Sondermeyer holds a patent for a "Method and apparatus for automatic volume control in an audio system." This invention features an improved adaptive filter that automatically adjusts signal gain based on the ambient noise level. The original music signal is processed through a normalized adaptive filter, which is then subtracted from the ambient room signal detected by a microphone. This process results in an error signal that estimates the ambient noise. The error signal is utilized to update adaptation coefficients, allowing the normalized adaptive filter to more accurately simulate the room transfer function. This innovation leads to a better estimate of ambient noise, enhancing the overall audio experience. The audio system is calibrated automatically upon initial use to determine adaptation coefficients and noise threshold levels, preventing runaway gain.
