摘要： The technology described in this document can be embodied in a computer-implemented method that includes receiving a first plurality of values representing a set of current coefficients of an adaptive filter disposed in an active noise cancellation system. The method also includes computing a second plurality of values each of which represents an instantaneous difference between a current coefficient and a corresponding preceding coefficient of the adaptive filter, and estimating, based on the second plurality of values, one or more instantaneous magnitudes of a transfer function that represents an effect of a secondary path of the active noise cancellation system. The method further includes updating the first plurality of values based on estimates of the one or more instantaneous magnitudes to generate a set of updated coefficients for the adaptive filter, and programming the adaptive filter with the set of updated coefficients
摘要翻译：本文中描述的技术可以体现在计算机实现的方法中，该方法包括接收表示设置在主动噪声消除系统中的自适应滤波器的一组当前系数的第一多个值。该方法还包括计算第二多个值，每个值表示当前系数和自适应滤波器的对应的先前系数之间的瞬时差，并且基于第二多个值，估计传输的一个或多个瞬时幅度表示主动噪声消除系统的辅助路径的影响的功能。该方法还包括基于一个或多个瞬时幅度的估计来更新第一多个值，以生成用于自适应滤波器的更新系数集合，以及用更新后的系数集合对自适应滤波器进行编程

摘要： An active noise reduction earbud includes a housing and a first feedforward microphone disposed in the housing. A first sound inlet opening extends through the housing and is configured to conduct external sound to the first feedforward microphone. The first sound inlet opening is configured to sit within a concha cavum of a user's ear and faces toward an auricle of the user's ear when the earbud is worn.
