Embodiment Construction

[0019] The invention will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments are shown. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the invention to those skilled in the art. the scope of the invention. In the drawings, like reference numerals refer to like elements.

[0020] A method for determining the distance (D) between the ears of a wearer of a sound generating object is disclosed. The method includes selecting a model for representing the shape of a head of a wearer of the sound generating object in order to obtain a central axis of the wearer's head.

[0021] The method includes associating (such as arranging or positioning) a first sound generating object with an ear of a wearer, wherein the fi...

Abstract

The present invention discloses a method for determining the distance (D) between the ears of a wearer of a sound generating object. The method comprises the steps of selecting a model for representing the shape of a wearer's head (2) of a sound generating object (4) in order to obtain a central axis (6) of the wearer's head. A subsequent step is to associate a first sound generating object with the wearer's ear, wherein the first sound generating object comprises a first accelerometer (10) and a second accelerometer (12), the respective accelerometers being arranged to measure At least one acceleration component (al, a2) intersecting the central axis of the wearer's head at substantially right angles. The two accelerometers are arranged such that a straight line (14) which intersects the central axis of the wearer's head at substantially right angles passes through the two accelerometers so that the acceleration components (a1, a2) have the same direction, the two The accelerometers are separated by a known distance (Δr). The method further comprises the steps of determining a value of a first acceleration component (a1) by a first accelerometer and determining a value of a second acceleration component (a2) by a second accelerometer when the wearer's head is in motion . In a further step, the distance (D) between the wearer's ears is determined on the basis of the obtained values ​​of the acceleration components (a1, a2). The present disclosure also relates to a first hearable sound generating object comprising two accelerometers.

Description

technical field [0001] The present disclosure generally relates to methods for determining the distance between the ears of a wearer of a sound generating object. Background technique [0002] In the field of virtual sound presentation through devices such as headphones, hearing aids or hearables, it may be expected that the listener receives externalized sounds, ie sounds that contain spatial cues. These spatial cues are usually generated by software on the basis of information available in the electrical audio signal. This creates the illusion of a virtual sound source that is external to the listener's head. [0003] For a satisfactory user experience in this regard, the physical (ie Euclidean) distance between the listener's two ears needs to be accurately established. This is the case, for example, if the general head-related transfer function (HRTF) needs to be adjusted to match the geometry of the user's head. A related example concerns bilateral beamformers, where...
