Abstract(in English) | We propose a new signal for measuring acoustic impulse responses of rooms and audio equipment. The signal, named as "warped TSP", is a combination of TSP(Time stretched pulses) and Logarithmic-TSP to improve the accuracy both in low and high frequency regions where the ambient or background noise is relatively high. We are able to define an optimal signal in accordance with the spectral distribution of the background noise. In this report, we describe the method for designing the warped TSP and show the dependency between the parameter and the spectral distribution. Moreover, we demonstrate the effectiveness of the warped TSP by measuring the room acoustics and headphone characteristics in the real environments. |
