Abstract:
An apparatus for mitigating noise in a printer can include a plate having a plurality of holes distributed across the plate and extending through the plate. A portion of the plurality of holes can be dimensioned and configured to absorb acoustic noise across a given frequency band and another portion of the plurality of holes can be dimensioned and configured to absorb acoustic noise across another frequency band in a media path of a printer. The apparatus further can include an acoustic baffling material to cover the plate and that can be configured to dampen the acoustic noise across the given frequency band and the other frequency band.
