HRTF describes how a given sound wave input (parameterized as frequency and source location) is filtered by the diffraction and reflection properties of the head, pinna, and torso, before the sound reaches the transduction machinery of the eardrum and inner ear (see auditory system).

HRTF是声音向我们传输而来时的头部相位与频率响应。 其变化取决于头部与身体的构造：鼻子，耳廓，嘴巴，额头和骨头密度；肩膀，双臂，双脚…。

2021年8月9日 · Head related transfer functions (HRTF) describe how sound signals bounce, scatter, and diffract when they arrive at the head, and travel towards the ears. HRTFs produce distinct sound patterns that ultimately help the brain infer the spatial properties of the sound, such as its direction of arrival, 𝜃.

This crate uses Head-Related Impulse Response (HRIR) spheres to create HRTF spheres. HRTF sphere is a set of points in 3D space which are connected into a mesh forming triangulated sphere. Each point contains spectrum for left and right ears which will be used to modify samples from each spatial sound source to create binaural sound.

2020年7月14日 · Measured vs. simulated HRTF at 1033 Hz (left), 2067 Hz (center), and 3962 Hz (right). The agreement in results exhibited here shows that you can use COMSOL Multiphysics to compute the HRTF of an actual human head and shoulder geometry, lessening the need for tedious HRTF testing of individual subjects.

2013年9月27日 · Head-related transfer functions (HRTFs) represent the acoustical transfer function between a sound source and the entrance of the blocked ear canal. Imposing HRTFs onto a non-spatial audio signal and playing back the result over headphones evokes the perception of a virtual 3D auditory space.

Head-related transfer function (HRTF) is an advanced way of rendering audio so that sounds appear to come from a specific point in 3D space, synthesizing binaural audio. It provides more realistic audio than standard spatialized audio. For example, with HRTF, the player can hear whether a character is above or below them.

2019年7月30日 · ·HRTF英文全名为Head Related Transfer Function，这是一种声音定位的处理技术，其原理非常复杂，由于声音会从耳廓、或肩膀反射到人耳内部，于是当我们用两个音箱模拟声音定位时，可以利用HD ITD的运算方式，来计算不同方向或位置声音所产生的大小和音调等，进而 ...

The HRTF is defined as the ratio between the Fourier transform of the sound pressure at the entrance of the ear canal and the one in the middle of the head in the absence of the listener [16].

2019年4月22日 · 单从这个词讲——Head Related Transfer Function ，是个处理技术吧，就是声学定位技术。 让人耳有明确的360度声音位置的体验感，更加真实，符合一些应用范围。 现在 …
