Application of Analysis of Variance and Taguchi Method for the Identification of Key Parameters and their Impact on Sound Measurement.

Abstract

This work is done to measure the sound density and improve its quality. And this is done by measuring the sound intensity in different situations and surroundings. To determine the effect of significant parameters throughout the sound measurement. The results of the various experiments of the sound measurement are viewed by applying some tools in Design of Experiments (DOF), Such as Taguchi method and Analysis of Variance (ANOVA) [1]. In these experiments there are four factors considered, they are temperature, distance, wind speed and angle of the sensor. These factors were chosen because they are the most parameters that can affect the quality of the sound. The results show that the factor speed is the most significant factor with percentage 1.79% according to the ANOVA table. Therefore, this work is considered as an effective tool to find the important parameters and their effect in sound measurement.
