抄録

<p>We examined a method to estimate the low frequency sound source position at outside a building using a microphone array placed on the ground surface. We conducted the field experiments using a loud speaker and microphones to verify estimation accuracy. From the results, it was found that the position of low frequency sound sources of 40 Hz can be accurately estimated within an area of 1 m when eight microphones are placed in a lattice. Furthermore, when four microphones were used, the sound source position could be estimated with an accuracy of several meters.</p>
