用于降低噪声的凹入表面特征和凸出表面特征
摘要：
公开了一种用于降低噪声的凹入表面特征和凸出表面特征。提供了一种车辆的乘客舱的面板(诸如仪表板)和一种降低发出的面板噪声的制造面板的方法。车辆的乘客舱的面板具有被形成为接纳装配部件、焊接部和紧固件的专属区域。在专属区域之间可获得空隙区域，所述空隙区域被形成为包括多个凸出表面特征和多个凹入表面特征，以用于降低发出的面板噪声。公开了一种用于在空隙区域中形成增大空隙区域的刚度以降低发出的面板噪声的多个凸出表面特征和多个凹入表面特征的方法。
摘要（英）：

Recessed and raised surface features for noise reduction are disclosed. A panel of the passenger compartment of a vehicle, such as a dash panel, and a method of making a panel with reduced radiated panel noise. A panel of the passenger compartment of a vehicle has committed regions that are formed to receive assembled components, welds and fasteners. Interstitial regions are available between thecommitted regions that are formed to include a plurality of raised surface features and a plurality of recessed surface features for reducing radiated panel noise. A method is disclosed for forming aplurality of raised surface features and a plurality of recessed surface features in the interstitial regions that increase the stiffness of the interstitial regions to reduce radiated panel noise.
