Together with the German microphone company Neumann they constructed the first binaural microphone: the KU80, which became the first commercially available dummy head for binaural recordings. But soon they realized that they had built a sufficiently working microphone for 3D sound recordings. Then, in the late 1960s three German engineers (Henning Wilkens, Georg Plenge und Ralf Kürer) at the Berlin Heinrich Hertz institute designed several dummy heads to be used for an objective comparison of room acoustics of concert halls. One problem for building a working dummy head was that some principles of human spatial hearing were still not understood: e.g. However, dummy head recordings were not successful for a long time. De Boer and Vermeulen also coined the term “Kunstkopf”. Roughly at the same time engineers (De Boer and Vermeulen) at the Dutch Philips laboratory constructed an artificial head to be used as a kind of binaural hearing aid. Mannequin for studying the influence of the head shape on sound recording quality (De Boer & Vermeulen 1939). Originally, Oscar had been designed as a test instrument for the improvement of telephone technology, but the team around Harvey Fletcher also used Oscar for some music recordings. engineers at Bell labs built an artificial head named “Oscar”. In the 1920s and 30s, different groups in the US and Europe experimented with binaural recording: e.g. Listening to binaural recordings with head phones is (sometimes) a really amazing experience – I will come back to this point in another post.ĭummy head recording has a long (pre-)history that dates back to the late 19th century: Clement Ader’s theatrophone was e.g. For playback, listeners rely on (good) head phones, one of the short comings of this technology as normal loudspeaker playback does not give you the acoustic cues for spatial sound localization. The human brain uses these tiny differences between the two ear/microphone signals (and other, e.g. The technique “exploits” basic principles of human spatial hearing: very small frequency adjustments that occur when sound wraps around the human head and is transformed by the outer and inner ear. The technology uses two microphones that are usually situated in the ears of a mannequin: this is why the technique is often called “dummy head recording”. ![]() To learn more about how and for what purposes Amazon uses personal information (such as Amazon Store order history), please visit our Privacy Notice.So what is Kunstkopf stereophony? Put simply, it is a 3D audio recording technology that enables listeners to relocate all recorded sound sources in space as if they were in the original recording situation.
