A head-related transfer function (HRTF), also known as anatomical transfer function (ATF), is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others. Generally speaking, the HRTF boosts frequencies from 2–5 kHz with a primary resonance of +17 dB at 2,700 Hz. But the response curve is more complex than a single bump, affects a broad frequency spectrum, and varies significantly from person to person.

  • 머리전달함수(Head Related Transfer Function, HRTF)은 동일한 소리를 전방위에서 발생시켜 방향에 따른 주파수 반응을 측정하여 3차원 함수로 정리한 것을 말한다. 한때, 일본에서 들어온 번역명인 두부전달함수(頭部伝達関数)가 쓰인적이 있었으나 현재는 학계에서 머리전달함수라는 정정한 용어를 사용한다. (ko)
  • 頭部伝達関数（とうぶでんたつかんすう、Head-Related Transfer Function, HRTF）とは、耳殻、人頭および肩までふくめた周辺物によって生じる音の変化を伝達関数として表現したものである。 HRTF ということばは周波数領域における表現に対してつかわれるが、これをフーリエ変換して時間領域において表現したものを頭部インパルス応答（Head-Related Impulse Response, HRIR）という。これは、1個のインパルスを発生させたときの応答特性である。 (ja)
  • 頭部相關傳輸函數（Head Related Transfer Functions，缩写：HRTF）又稱為ATF（anatomical transfer function），是一種音效定位演算法。 HRTF是一組濾波器，即利用HD （Interaural Time Delay）、IAD（Interaural Amplitude Difference）和等技術產生立體音效，使聲音傳遞至人耳內的耳廓，耳道和鼓膜時，聆聽者會有環繞音效之感覺。透過DSP，HRTF可實時處理虛擬世界的音源。 (zh)
  • Die Head-Related Transfer Function (meist nur HRTF, seltener kopfbezogene oder Außenohr-Übertragungsfunktion) beschreibt die komplexe Filterwirkung von Kopf, Außenohr (Pinna) und Rumpf. Diese Amplituden-Auswertung ist neben den Laufzeitdifferenzen zwischen den Ohren wesentliche Grundlage unseres akustischen Lokalisationssystems. (de)
  • Función de transferencia relacionada con la cabeza (HRTF) en inglés llamada "Head-related transfer function". Es una respuesta que caracteriza cómo un oído recibe un sonido desde un punto en el espacio. A medida que el sonido golpea al oyente, el tamaño y la forma de la cabeza, las orejas, el canal auditivo, la densidad de la cabeza, el tamaño y la forma de las cavidades nasales y orales, transforman el sonido y afectan la forma en que se percibe, aumentando algunas frecuencias y atenuando otras. En términos generales, la HRTF aumenta las frecuencias de 2 a 5 kHz con una resonancia primaria de +17 dB a 2,700 Hz. Pero la curva de respuesta es más compleja que un solo golpe, afecta a un amplio espectro de frecuencias y varía significativamente de una persona a otra. (es)

  • La fonction de transfert relative à la tête ou HRTF ((en) head-related transfer function) caractérise par une fonction de transfert mathématique les transformations apportées aux ondes sonores par le corps d'un auditeur, principalement la tête, le pavillon de l'oreille et le conduit auditif, qui permettent à l'être humain de repérer l'origine d'un son, tant en azimut (horizontalement) qu'en site (verticalement).
