PROBLEM TO BE SOLVED: To provide a sound insulation degree measuring device capable of measuring sound insulation performance to a high frequency generating component without increasing an operation amount.;SOLUTION: A sound insulation degree measuring device 1 has a speaker 10, a microphone 20, and a control portion 40. The speaker 10 has a plurality of sound sources. The microphone 20 receives sound from the speaker 10, and measures an acoustic level. The control portion 40 calculates a virtual sound reception level received by the microphone 20 when an obstacle does not exist between the speaker 10 and the microphone 20, on the basis of a positional relationship between the speaker 10 and the microphone 20 and transmission characteristics for measuring a sound insulation degree; and calculates a sound insulation degree on the basis of the calculated virtual sound reception level and a sound reception level measured by the microphone.;COPYRIGHT: (C)2013,JPO&INPIT
