External-Ear Replica for Acoustical Testing

Abstract: An artificial ear was designed to simulate the mechanical and acoustical properties of the external ear, up to and including the impedance of the eardrum. The sensing element is a B & K 4132 electrostatic microphone terminating a simulated earcanal with an acoustical impedance-matching network that, combined with the microphone, furnishes the eardrum impedance. The canal proper has dimensions approximating those of the real ear and is surrounded by a plastisol pinna of realistic dimensions and texture. The… Show more

“…In 1966, Bauer et al of the CBS laboratories [90,91] presented amanikin ( Figure 11)based on anthropometric data from sevenastronauts 16 .The manikin wasdeveloped for measurements of sound transmission through astronaut helmets and testing of communication equipment, such as headphones and microphones, to be used in spaceships. Fort his reason, the manikin also had an artificial voice, implemented using aloudspeaker.…”

“…Für die Kalibrierung von Kopfhörem und andere Messungen der subjektiven Akustik wurde ein künstlicher Kopf entwickelt, bei dem der Gehörgang anatomisch richtig nachgebildet und die Impedanz des Trommelfells durch ein elektrisches Netzwerk realisiert wurde [112], [113]. Ein einfacherer künstlicher Kopf hat sich bei Richtungshörversuchen bewährt [114].…”
