PROBLEM TO BE SOLVED: To provide a measurement device capable of improving accuracy of measurement results of an impulse response and frequency characteristics of a measurement object system including an output device and a reception device, and further to provide a program.SOLUTION: First measurement data and second measurement data are obtained from first TSP signal data 241A and second TSP signal data 241B, data of a TSP signal in which amplitude components are controlled in consideration of average frequency characteristics, in which a low-frequency amplitude is relatively emphasized than a high-frequency amplitude, the first measurement data and the second measurement data are combined together and frequency characteristic data 235 are obtained even when the average frequency characteristics of a measurement object system, for example, sealed headphone, have variations depending upon a frequency. Consequently, it is possible to measure the measurement object system with accuracy higher than that of a conventional method. |
