Abstract:
An object detection device includes a microphone array that includes a plurality of non-directional microphones, and a processor that processes first sound data obtained by collecting sounds by the microphone array. The processor generates a plurality of items of second sound data having directivity in an arbitrary direction by sequentially changing a directivity direction based on the first sound data, and analyzes a sound pressure level and a frequency component of the second sound data, and determines that an object exists in a first direction in a case where a sound pressure level of a specific frequency, which is included in the frequency component of the second sound data having directivity in the first direction of the arbitrary direction, is equal to or larger than a first prescribed value.

Claim (Index 5):
The object detection device of  claims 1 ,\n wherein the processor detects an approach of the object based on change in time of the sound pressure level in the specific frequency, and determines that the object exists in a prescribed area in a case where the approach of the object is detected and the sound pressure level of the specific frequency is equal to or larger than a third prescribed value which is larger than the first prescribed value.
