Mannequin heads with ear microphones capture realistic spatial audio for recording

Evidence

In some cases it is practical to use dummy heads in binaural response measurements and recordings (Møller, 1992). The dummy heads are also known as head and torso simulators, artificial heads, or binaural microphones. They are designed to approximate the head-related acoustics of a typical human subject. Figure 12.4b shows a dummy head with a removable pinna unit, where condenser microphones are used in place of the ear drums. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1411
