Title: Andre L Goldstein: Innovator in Personal Listening Devices
Introduction
Andre L Goldstein is a notable inventor based in San Jose, California. He has made significant contributions to the field of personal listening devices, holding a total of five patents. His work focuses on enhancing user experience through innovative technologies that improve sound quality and noise cancellation.
Latest Patents
One of Goldstein's latest patents is for a close-talk detector for personal listening devices with adaptive active noise control. This invention detects a user's speech signal while an adaptive noise cancellation (ANC) process is active. It helps prevent the filter coefficients of the ANC process from being corrupted, thereby reducing the risk of adaptive filters diverging. The detector uses a vibration sensor signal and microphone signals to assert a signal that can slow down or halt the adaptation of the filter when speech is detected. This allows the ANC process to resume its normal adaptation rate when no speech is detected.
Another significant patent by Goldstein is for adaptive audio equalization for personal listening devices. This invention features an audio processor with an ANC processor that computes an S-filter to estimate the transfer function from an earpiece speaker to an error microphone. The ANC processor produces an anti-noise signal to reduce ambient noise. Additionally, an adaptive equalization processor adjusts an EQ filter while audio content is filtered before being delivered to the speaker.
