초록

An acoustic silencer for dampening unwanted resonant and pressure pulses in a pipe or duct work and includes an expansion chamber having an enclosed volume through which a pipe or duct work extends, thereby defining an annular volume within the enclosed volume between the process pipe and the expansion chamber. An insert disposed within the annular volume extends along the length of the process pipe and forms an acoustic volume within the annular volume and defines a resonant passage length that is of a length so as to dampen one or more frequencies of t...
