I bought this air conditioner to use in the room I am using while working from home. The reason I selected this model after researching other brands and models, is that it was advertised as quiet. I needed a quiet model since I participate in many video calls for work.  This air conditioner did a fantastic job during the warm summer days -- both in cooling and sound level!  I even asked coworkers while on a call if they could hear the unit when it was on, and they said they couldn't hear it at all. With the WiFi capability and LG ThinQ app on my phone, I was able to turn the unit on and off as needed to keep the room at a comfortable temperature without having to leave my chair.
