用于检测并衰减通信系统中的吸气噪声的方法和装置
摘要：
用于检测并衰减在连接到加压空气传递系统的通信系统中的吸气噪声的方法，该方法包括步骤：基于吸气噪声生成吸气噪声模型(912、1012)；接收包括吸气噪声的输入信号(802)；将输入信号与噪声模型做比较(810)，以获得相似性测量；基于相似性测量确定增益因数(854)；以及基于该增益因数修改输入信号(852)，其中基于该增益因数衰减输入信号中的吸气噪声。
摘要（英）：

A method for detecting and attenuating inhalation noise in a communication system coupled to a pressurized air delivery system, the method including the steps of: generating an inhalation noise model ( 912, 1012 ) based on inhalation noise; receiving an input signal ( 802 ) that includes inhalation noise; comparing ( 810 ) the input signal to the noise model to obtain a similarity measure; determining ( 854 ) a gain factor based on the similarity measure; and modifying ( 852 ) the input signal based on the gain factor, wherein the inhalation noise in the input signal is attenuated based on the gain factor.
