What is an important consideration when installing ductwork in a residential setting to reduce noise?

Choosing flexible duct options is a significant consideration when it comes to reducing noise in a residential setting. Flexible ducts can absorb vibrations and sound better than rigid ducts, which tend to transmit noise more effectively. This characteristic makes flexible ducts particularly advantageous in reducing the transmission of both airborne noise from the HVAC system and structure-borne noise generated by airflow within the system.

Additionally, flexible ducts are easier to navigate in tight spaces and can minimize sharp bends that would otherwise increase turbulence and noise and contribute positively to the overall duct design, ensuring a quieter operation. In contrast, using larger ducts might help to reduce velocity and potentially lower noise levels, but it may not be practical in many residential applications where space is limited or specific physical constraints exist.

Increasing airflow velocity generally increases noise levels, as high velocity can lead to turbulence and a louder system operation, while adding insulation typically provides more effective noise reduction for existing ductwork systems rather than being a primary consideration during installation. Therefore, the use of flexible duct options stands out as the most effective choice for noise reduction in a residential ductwork installation.
