Title: The Innovations of Andrew J Langley
Introduction
Andrew J Langley is a notable inventor based in Welwyn, GB. He has made significant contributions to the field of noise reduction technology, holding a total of 7 patents. His work focuses on developing systems that enhance sound quality and reduce unwanted noise in various environments.
Latest Patents
One of Langley's latest patents is a noise-reducing system. This active control system is designed to attenuate tonal noise in a defined region. The system includes sensors that generate signals indicative of the residual noise after attenuation, as well as the uncontrolled sound affecting the region. It features a signal processing circuit that processes these signals differently based on their tonal content. An adaptive filter is supplied with at least one of the generated signals, and its characteristics are controlled by the processing circuitry. Additionally, a transducer produces tonal-noise-attenuating disturbances in the region, while delay means are used to manage signals related to uncontrolled noise during the adaptive filtering process. This innovative system finds direct application in personal headsets or ear defenders.
Another significant invention by Langley is the adaptive resonator vibration control system. This technology aims to improve the effectiveness of noise cancellation in various applications.
