Abstract
In this research, the masking performance and the mental influence of five representative maskers are compared. Sound masking is an effective method to provide speech privacy and sound insulation in the environment where the structural sound insulation solutions, such as building a inner wall or a private room, are difficult to be carried out. In the preceding studies of sound masking, various maskers have been proposed. However, there is few research which comprehensively compares these various maskers. Therefore, this research aims to compare and investigate these maskers. As the first stage, this report introduces the generating principle and method of the maskers, and investigate the features of the maskers by frequency property analysis. Moreover, a trial to evaluate the sound masking performance by using the correlation coefficients of the time domain signals is conducted.
