Multi-muffler sound attenuator assembly

摘要

A unitary, skid-type sound attenuator assembly for simultaneously managing sound from multiple sources. The assembly may include a dedicated muffler for each sound source. In turn, each of these mufflers includes an outlet for directing sound toward a location such as between the various mufflers of the assembly so as to provide an added level of noise cancellation. Additionally, the assembly may include an attenuator at such a common central location for further noise reduction. The attenuator may also serve a filtering function, for example where the sound sources are engines and the assembly is utilized for managing exhaust therefrom such as in an oilfield environment.

主权项

1. A multi-muffler assembly for attenuating sound from multiple sources, the assembly comprising:
a first muffler device having a first inlet coupled to a first of the sources and a first outlet to direct muffled sound therefrom; and a second muffler device having a second inlet coupled to a second of the sources and a second outlet to direct muffled sound therefrom, the muffled sound from the first outlet directed to the muffled sound from the second outlet at a common location for attaining a degree of sound cancellation.
