How are humans able to focus in on one voice only in a crowded noisy environment and yet microphones lack this talent? Professor Mike Brookes from Imperial College London shows how his research does something similar using multiple microphones. This allows you to listen to selective conversations in a crowded room; useful for hearing aids wearers and spies.
