ANCoustics: A Systematic Analysis in Acoustics with Active Noise-Cancellation Technology

With the advancement of technology, especially regarding electronics and digital progression, the paper focuses on the provision of information on how acoustic factors relate to analog electronics, from principles and components, trends and applications, issues present, and a proposed solution to combat noise and acoustic discomfort. Sounds and acoustics are encountered in daily living, and with that comes relevant issues, mainly noise pollution and acoustic discomfort. Aside from the life-easing roles of electronic acoustics in society through modern applications in devices and components such as mobile devices and electrical instruments, there are also acoustic issues that can be found. With that, aside from presenting reliable and credible pieces of literature found on the trends and applications of analog electronics in acoustics, the paper also presented different sources that identified related issues and challenges, namely noise present in different common venues such as one’s neighborhood, public spaces, shopping malls, churches, and recording studios. To combat the issues, the authors propose an active noise-cancelling (ANC) post module system which consists of microphones, filter, inversion circuit, power amplifier, and speaker. The paper provides a brief but substantial learning experience and overview on vital and significant knowledge and innovation on acoustics through analog electronics, solving timely and relevant challenges on noise and acoustic discomfort.
