SOUND PERFORMANCE MEASURING DEVICE OF A SOUND WAVE TRANSMITTING AND RECEIVING UNIT AND A COMPENSATION METHOD THEREOF USING A SOUND WAVE RETRO-REFLECTION DEVICE

摘要

PURPOSE: A sound performance measuring device of a sound wave transmitting and receiving unit and a compensation method thereof are provided to reflect incident sound waves to a reflection plane in the incident direction using a sound wave retro-reflection device. ;CONSTITUTION: A sound performance measuring device of a sound wave transmitting and receiving unit comprises: a sound wave retro-reflection device(100) provided with a main body unit and a retro-reflection unit reflecting the sound waves incident to the main body unit in the incident direction from a reflection plane; a sound wave transmitting and receiving unit(10) provided with many transducers generating sound waves and receiving the sound waves reflected from the reflection plane; a selection unit(192) selecting the transducer generating sound waves among the transducers; and an analysis unit(194) analyzing the sound waves reflected from the reflection plane among the sound waves generated from the selected transducer by the selection unit.;COPYRIGHT KIPO 2011
