Causes of noise in window-type air conditioners and anti-vibration soundproofing measures
Contents
Window-type air conditioners are essential in homes and offices in summer, but the noise they generate during operation may affect quality of life and work efficiency. In this article, we will take a closer look at the causes of noise in window-type air conditioners and provide a detailed set of anti-vibration and soundproofing measures to make your air conditioner quieter and more comfortable.
Soundproofing for window units｜Causes and types of noise in window-type air conditioners
To solve the problem more effectively, we should first take a closer look at the causes and types of noise in window-type ACs.
Structure-borne noise
Structure-borne noise is caused by vibrations generated when internal components of the air conditioner operate. These vibrations are transmitted through the unit structure and eventually create noise on the mounting platform or wall. For example, vibrations produced when the compressor is running are a typical form of structure-borne noise.
Aerodynamic noise
Aerodynamic noise comes from airflow turbulence created by the internal fan during AC operation. As air passes through the fan, condenser and evaporator, unstable vortices form and generate noise.
Noise caused by improper installation
Improper installation may cause poor contact between the unit and the window or wall, creating paths for noise to form and spread. In addition, unstable installation or a tilted unit may also cause noise.

Once you understand the causes of noise, you can take more precise steps to reduce the noise of a window-type air conditioner.
Choose an AC with a low-noise design
When comparing AC noise, check the manufacturer's indoor and outdoor data, fan speeds and test conditions, and do not confuse sound pressure with sound power. Inverter or low-noise names do not guarantee a quiet result in every location; installation, fan and surroundings must also be assessed.
Proper AC installation
During AC installation, ensure the unit is in close contact with the window or wall and kept level. If needed, have it installed by a professional to ensure stability.
Use vibration-damping pads
Placing vibration-damping pads between the air conditioner and the installation platform can effectively reduce structure-borne noise. The pads can be made of rubber, EVA foam and other materials with good shock-absorbing performance.
Soundproof window
Consider installing a soundproof window on the window where the AC is installed to prevent noise from spreading further. A soundproof window can effectively reduce sound transmission and provide better indoor sound insulation.
Carry out regular maintenance
Only maintain filters and external surfaces that your model allows to be removed and washed. Internal parts, the evaporator and the outdoor condenser require separate assessment; unusual noise may also involve mounting or components, and cleaning cannot guarantee all noise will be eliminated.
Use sound-insulating materials
Soundproof materials such as acoustic foam and soundproof panels can be used around the air conditioner to reduce noise transmission. At the same time, choose fire-resistant and moisture-resistant materials to ensure safe use.
Reduce the air conditioner’s operating speed
When using an air conditioner, you can choose a lower fan speed to reduce airflow noise. In addition, using the timer function to switch off the unit at the right time also helps reduce noise.
This shows that choosing a low-noise AC design, installing the AC correctly, using anti-vibration pads, soundproof windows, regular maintenance and reducing operating speed can also effectively reduce AC noise and improve quality of life and work efficiency.
Find professional help
To improve the sound insulation of a window-type AC, it is important to seek help from a professional team. They can provide suitable shock-absorbing and sound-insulating measures, and carry out thorough cleaning and maintenance to ensure quiet operation and improve living comfort.
