Choose a smooth (and round) tube as opposed to a flexible one. The latter gives more resistance when the air passes through, which diminishes the actual airflow and increases the noise. Furthermore, the flexible tube is often thinner, resulting in greater heat loss and an increased risk of condensation. Drops of water from the hood might be the result, especially if there is no return valve mounted on the outside wall in order to prevent cool air from entering the duct system.Consider insulating your duct in order to minimize condensation and noise. If you are acquiring a wall mounted cooker hood, you could also consider attenuating the noise by adding insulation around the chimney. You could also consider the relatively simple solution of simply building a chimney cover in plasterboard to be painted in your kitchen’s colors.
