The Standardization of Partitioning Audible Sound by A7B

Abstract

Scholars and analysts of sound hope to have a standard system that is self-explanatory in assigning different tones including low, mid, and high, to any given sound with certain pitch. Yet, such system has not been developed, or recognized in the field. The absence of the system may bring about different results in analyzing sounds due to the lack of standardized vocabulary and objectivity. This paper suggests a way to improve the current situation using 7 bandwidths of sound in order to standardize the process of partitioning tones and thus proposes the implementation of the Acoustic 7 Bandwidths (A7B) system as a portioning system of audible sound, an indicator of sound tone in other words. The proposed system is based on the proper partitioning of sounds in audible range to humans and has an advantage of relatively easy implementation. The following 7 bandwidths of sound contain same cents range of frequency for each category: ultra-low tone, low tone, mid-low tone, mid-tone, mid-high tone, and ultra-high tone. The use of the standardized system of partitioning sound through A7B will provide objective analysis and fair comparison of sounds with respect to tone and frequency.
