Abstract/Summary
Active Noise and Vibration Control (ANVC) systems are of increasing relevance as urban areas get more densely populated with people and their noise sources. Community noise is of great importance to many forms of transit that aim to bring mobility to a region with minimal subsequent noise pollution. Active Vibration Control (AVC) is an emerging field of research which can be employed to further mitigated unwanted harshness in an acoustic environment by extending the principals of Active Noise Control (ANC)to solid mediums using surface transducers and piezoelectric actuators.
The Audio Research Codec (ARC) is a compact, cost-effective system designed for research and development of active noise cancellation and active vibration control systems. The ARC system is designed to implement several parallel ANC channels for research in 3-Dimensional noise cancellation. With 16 input and output channels, it supports analog microphone and digital pulse density modulation (PDM) sources as well as various transducers such as piezoelectric actuators and loudspeakers. The system facilitates the exploration of ANC and AVC algorithms such as FXLMS, LMS, AP, and RLS for noise reduction in diverse applications. Boasting a user-friendly serial monitor interface, expandable data storage, and real-time digital signal processing, the Audio Research Codec is an affordable tool for researchers, students, and professionals alike.
