![]() Some binaural-head microphones were developed for purposes other than music recording, such as medical, psychological, space and aeronautical acoustics research. ![]() Sennheiser used to make a model, the MKE-2002, that had the microphones mounted on a type of doctor's stethoscope and Soundman makes the OKMI and II in- ear microphones. A variation on this idea would have the recordist place small microphones into their own ears to capture the sound from their own unique perspective. It's been called many names: artificial-head, binaural-head, dummy-head, head-and-torso-simulator (HATS), and (adopting the German term) kunstkopf microphone. Those reflection patterns cause different comb- filtering effects, giving a unique signature frequency response for each direction of sound.Ī dummy-head microphone is a two-channel system where the pair of recorded signals is meant to be reproduced independently to each ear, hence the term binaural. The directional cues result from the variations in reflection patterns occurring at the outer ear. ![]() The goal here is to imitate our natural hearing system, particularly the way our ears collect the spatial characteristics of any sound and its surrounding environment. This imitation should then mimic the physical properties and paths that a sound follows to our eardrums, with the left and right microphone diaphragms acting as eardrums. Construct a mannequin imitation of a human head with a microphone inserted into each of its ears. Dummy-head microphones - the idea behind them is as simple as their name implies.
