# Can two microphones placed within centimeter distance together measure a distance of the sound source?

I have placed two microphones placed within 1 or 2 cm distance. They can receive and record sounds around them. I want to detect the distance of the sound source (specially human voice) and the direction of the sound source using those microphones. Is it feasible when the distance of the sound source is short (i.e. around 10 cm).

• two microphones can detect direction, not distance May 7 at 19:15
• Any way to estimate distance from microphones? Even using more than two mic? @jsotola May 7 at 19:21
• think about it ... a pair of microphones can be used to determine the direction of the sound source ... adding a third microphone gives you three pairs of microphones May 7 at 19:25
• You could use the mics to determine the distance between each other... May 7 at 19:28
• Yes, but why do you need to determine the distance? What use is knowing the distance from someone's ears to their mouth? Your question says the microphones are 1 - 2 cm apart - now you're mentioning earbuds which would be the width of a head apart. Can you see why your readers could be confused? May 7 at 22:04
