AUTOMOTIVE NOISE MITIGATION

A method for noise cancellation includes monitoring a system for a current operating point, monitoring the system for a predetermined disturbance, and in response to the predetermined disturbance, determining the disturbance to be in one of a transient or steady state response period. A set of data...

Beschreibung
Zusammenfassung:	A method for noise cancellation includes monitoring a system for a current operating point, monitoring the system for a predetermined disturbance, and in response to the predetermined disturbance, determining the disturbance to be in one of a transient or steady state response period. A set of data is selected corresponding to the current operating point of the system, the disturbance, and the response period from a database containing predetermined noise cancellation waveform data. A noise cancelling waveform is output to audio transducers based upon the selected set of data. 一种用于噪声消除的方法包括：对于当前操作点监视系统；对于预定干扰监视系统；以及响应于预定干扰，确定干扰处于瞬态或稳态响应周期中的一个。从包含预定噪声消除波形数据的数据库中选择与系统的当前操作点、干扰和响应周期相对应的数据集。基于选择的数据集将噪声消除波形输出到音频换能器。
