摘要： A lined duct is divided into two parallel branches by means of a rigid partition. The phase speed of the fundamental mode in each branch depends on the liner configuration and can differ markedly from the free-space phase speed. When the liners in the two branches are not the same, the corresponding phase speeds will be different and a relative phase lag between the waves in the two branches results. This, in turn, leads to interference between these wave components (and their reflections) both at the exit and entrance of the parallel branch pair. This interference can be exploited for the purpose of obtaining a low-frequency attenuation which is substantially larger than the attenuation of the unpartitioned duct.
摘要翻译：衬里的管道通过刚性隔板分成两个平行的分支。每个分支中基模的相位速度取决于衬套结构，并且可以与自由空间相位速度明显不同。当两个分支中的线束不相同时，相应的相位速度将不同，并且两个分支中的波之间产生相对相位滞后。这反过来又导致平行分支对的出口和入口处的这些波浪分量（及其反射）之间的干扰。这种干扰可以用于获得基本上大于未分割管道的衰减的低频衰减的目的。

摘要： A liner assembly includes a plurality of aligned passages providing a large open area combined with openings much smaller than a length of the passages. The plurality of passages are disposed parallel with each other and include an opening transverse to incident sound waves. The passages are separated by walls and are blocked at an end distal from the openings. Sound waves incident on a face of the liner enter the passages and are dissipated by viscous losses. Sound energy is further dissipated as thermal energy to the walls of the passages. The long narrow passages provide the desired visco-thermal losses for sound energy in a broad frequency range.

摘要： An elevator cab ceiling (22) includes an upper ceiling panel (26), a lower ceiling panel (28), and a ventilation channel (30) extending between the upper ceiling panel (26) and the lower ceiling panel (28). The ventilation channel (30) extends at an oblique angle relative to the upper ceiling panel (26) and separates space between the upper (26) and lower (28) ceiling panels into an upper cavity (32) and a lower cavity (34). A plurality of partitions (36) are formed within at least one of the upper (32) or lower (34) cavities. In one example, an acoustically resistive element (42) extends at least partially along a portion of the ventilation channel (30). The plurality of partitions (36) and the acoustically resistive element (42) cooperate to reduce noise levels transmitted into an elevator cab (10) via the ventilation channel (30).

摘要： The sound attenuating device of the present invention is a bulk layer connected to a support member which forms a plurality of Helmholtz resonators. This invention is particularly useful in a vehicle where the bulk layer attenuates high frequency noise, i.e. above about 1000 Hz, while the resonators can be tuned across the device to absorb at different lower frequencies in different areas of the device.

摘要： An active noise control system includes sensors 16,26 which detects noise 114 and provides electronic signals to an active noise control (ANC) controller 20. The controller provides electronic anti-noise signals to a speaker 24 which is connected to, and provides acoustic anti-noise into, a plurality of active resonators 120-124. The resonators 120-124 are disposed successively along the propagation direction of the noise 114 and provide time-delayed anti-noise acoustic output signals each of which attenuates a portion of the noise 114. The phasing of the anti-noise signals from the resonators 120-124 may be accomplished by acoustic and/or electronic time delays.
