(57) Abstract :
A compressor system and a method of reducing noise in the compressor system. The compressor system includes an inlet port
configured to receive gas, an outlet port configured to output compressed gas, and a compressor pump connected to the inlet port
via a pneumatic line and to the outlet port. The compressor pump is configured to pressurize gas input through the inlet port and to
output a compressed gas through the outlet port. The compressor pump generates noise during operation of the compressor pump.
The compressor system further comprises a side-branch resonator having a housing forming a cavity and an elongated member
connected to the housing. The elongated member is pneumatically connected to the pneumatic line between the inlet port and the
compressor pump. The side-branch resonator is configured to substantially reduce noise generated by the compressor pump, to
monitor an operation of the compressor pump, or both.
