Presently, value of passenger vehicle shifted from more than conventional transporting tools. Its comfort become important consideration beside its functionality, and no exception for its cabin noise also. Vendors and engineers have given their effort in minimizing vehicle cabin noise within many methods for many years. One of them is Active Noise Control (ANC) method by giving opposite signal called anti-noise that interfere and cancel each other with the noise itself. BBTA3 - BPPT have performed development of ANC system since last year, especially for medium passenger vehicle. Implementing Least Mean Square (LMS) algorithm and broadband feedforward strategy, least significance but a promising result have been achieved by the 1st prototype that have been tested in mid of 2020. Around 1 dB of best average decrement of cabin noise have been noted for its lab-scaled testing, and less than 0.5 dB for its road test result. Comprehensive approaches have been recommended for next step of development, including algorithm enhancement, hardware specification improvement, and spin-off research about acoustic-noise energy harvesting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
