Abstract:
A sound pressure gradient microphone includes: a first non-directional microphone; a second non-directional microphone; a delay device that receives an output of the second non-directional microphone; and a subtractor that receives an output of the first non-directional microphone and an output of the delay device. The subtractor outputs a difference between the output of the first non-directional microphone and the output of the delay device. A phase of the first non-directional microphone is ahead of a phase of the second non-directional microphone.

Claim (Index 7):
A sound pressure gradient microphone comprising:\n a first non-directional microphone; a second non-directional microphone; a first digital filter that receives an output of the first non-directional microphone; a second digital filter that receives an output of the second non-directional microphone; a delay device that receives an output of the second digital filter; and a subtractor that receives an output of the first digital filter and an output of the delay device, and outputs a difference between the output of the first digital filter and the output of the delay device, wherein the first and second digital filters are set so as to achieve the state where a phase of a signal output from the first digital filter is ahead of a phase of a signal output from the second digital filter.
