Abstract
An acoustic cavity conditions the air flowing from a blower to reduce noise in the airflow. The air flowing directly out of the blower exhibits pulses produced by each impeller blade or fan blade. The airflow noise is thereby induced at certain frequencies. Printing operations inside a printer can also occur at specific frequencies. Introducing the airflow directly into certain areas of a printer can result in the noise frequencies and printing frequencies to combine and produce noticeable printing artifacts. An acoustic cavity tuned to dampen the airflow noise can condition the airflow and eradicate the printing artifacts.
