PURPOSE: A sound pressure measurement device and an operating method thereof are provided to appropriately control the volume by measuring sound pressure of a receiver. CONSTITUTION: A sound pressure measurement device comprises a user input part(120), a control part(115), a receiver(105), a microphone(110), and a sound pressure measuring part(116). The user input part generates a sound pressure measurement signal tor measuring sound pressure. The control part plays a test file depending on the sound pressure measurement signal. The receiver outputs sound to the test file. The microphone senses the sound output from the receiver. The sound pressure measuring part measures sound pressure to the sound sensed by the microphone. |
