A sound suppression chamber for a heating, ventilation and air conditioning (HVAC) air handling assembly including a first end, a second end, and a middle portion. The first end includes an aperture that resonates with airflow from the HVAC air handling assembly, the airflow from the HVAC air handling assembly generating an incident sound wave corresponding to a target tone. The second end is closed and opposite the first end. The middle portion extends between the first end and the second end. The first end, the second end, and the middle portion defining a cavity of the sound suppression chamber. The sound suppression chamber generates a reflected wave that is 180 degrees out of phase from the incident sound wave and reflected into the HVAC air handling assembly through the aperture to suppress the target tone.
