Range hoods are increasingly popular for their ability to eliminate smoke and odors, providing a fresh and clean environment for users. However, during usage, the machine can become noisy, affecting occupants. Join Mytour to explore the reasons and remedies for a noisy range hood in this article.

A loud range hood can be discomforting for users.
The fundamental cause of a noisy range hood is often purchasing a low-quality model. In these inferior models, the motor is typically weak, and the components are loosely installed, making the operation difficult and generating loud noise.
Modern dust extractors are often equipped with various suction modes to accommodate different kitchen spaces. In the case of a large kitchen but a small range hood with low power, you are forced to choose a high suction mode, leading to a noisy extractor fan.
Range Hood with High Suction Mode
Incorrect placement during range hood installation can lead to excessive noise. Installing the range hood on an uneven or unstable surface will prevent the machine from having a firm support. During startup, the hood will shake, collide with the wall or cabinet, causing annoying noises.
Insufficient exhaust diameter, folding, or loose connections can cause the motor to operate in a compressed air condition. The internal engine gets clogged, unable to release air properly, leading to an overloaded and noisy extractor fan.

The duct with multiple bends creates noise.
A common but often overlooked cause is the presence of foreign objects inside the extractor fan. These can include small insects that crawl in or objects inserted by curious children through gaps, causing the fan blades to jam or break, resulting in noisy operation.
The noticeable difference between high-quality and lower-grade range hoods is the noise level. Top-notch models are equipped with modern motors, ensuring smooth operation and minimizing noise for users. Even at low suction power, the sound of a modern range hood is around 41dB, comparable to a whisper, making it barely audible. At maximum suction, the device generates only about 60dB, equivalent to normal conversation, without causing disturbance to people nearby.
For low suction mode, the motor of the range hood operates more quietly than in high suction mode. You can try turning on the range hood at the lowest level before cooking and only increase the suction power when the food is almost cooked, and smoke and steam rise significantly. Avoid starting with high suction power to prevent the range hood from operating overloaded and producing loud noise.
If you notice signs of impact around the range hood, there is a possibility that the installation is not secure. Reinstall the hood correctly or relocate it to a flatter position, while still staying close to the stove, ensuring maximum suction efficiency.

The range hood is installed in a spacious and flat position
When selecting a smoke duct, opt for a duct with a diameter of 150mm (6 inches), sturdy structure, and smooth surface. Smaller-sized, less rigid ducts with ribbed surfaces may cause unstable airflow, resulting in loud noise for the range hood.

Straight Installation with Fewer Bends
Install the duct straight, with minimal bends, and the shorter the length, the better. These factors contribute to effectively reducing noise for the range hood.
