A study on individual frequency bandwidth using addition signal in noise signal

Abstract

This paper proposes different ways to study individualized bandwidth. This bandwidth is used in noise signal for recognition and analysis in various ways but previous methods only apply weighted dB(A) and dB(C) to sound pressure level or one in low frequency scope. Also, there are A weight sound level (LA), NC curve (Noise Criteria Curves), and NR curve (Noise Rating Curves). This research tries to find out about individualized bandwidth by using frequency bandwidth and applying this to different fields such as recognition, analysis, and reduction.
