Title: Teik Lim: Innovator in Active Noise Control Systems
Introduction
Teik Lim is a notable inventor based in Mason, OH (US), recognized for his contributions to the field of active noise control systems. With a total of 3 patents to his name, Lim has developed innovative solutions aimed at enhancing audio experiences in various environments.
Latest Patents
One of his latest patents is titled "Subband algorithm with threshold for robust broadband active noise control system." This invention describes an active noise control (ANC) system that utilizes a speaker and one or more processors. The processors implement an adaptive subband filtered reference control algorithm that applies thresholds to reference and error feedback signal paths. This system effectively responds to broadband non-Gaussian impulsive reference signals indicative of road noise in vehicles, allowing for partial cancellation of the noise through the speaker output.
Another significant patent is the "Variable bandwidth delayless subband algorithm for broadband active noise control system." This ANC system also includes a speaker and processors programmed to implement a delayless subband filtered-x least mean square control algorithm. The algorithm features a variable bandwidth discrete Fourier transform filter bank with multiple subbands. It responds to broadband white noise reference signals indicative of road noise, exhibiting a uniform gain spectrum across the defined frequency range and partially canceling the road noise via the speaker output.
