Extension of a signal safeguarding-based acoustic system measurement method -- Reducing requirement for signal-dependent and random response measurement --

Abstract (in Japanese) (See Japanese page) 
(in English) We propose an extension of a signal safeguarding-based acoustic measurement method that enables using any sounds, such as music recordings, to test acoustic systems. This article removes restrictions in our previous proposal of a signal safeguarding-based acoustic measurement method. Our previous proposal required strict periodicity in safeguarded test signals because of the periodic nature of discrete Fourier transform. We propose substantially lengthening the test signal segment and smooth-shaping segment edges without deteriorating the safeguarding and practically made segment as a periodic signal. Preliminary tests using an existing acoustic system illustrated the feasibility of the proposed method. Formulation of the method and clarification of the design procedure is the next research topic.
