Soundproofing finds application not only in rooms where isolation is expected, such as sound and music rehearsal rooms, but also in open space areas where you encounter unpleasant echoes. Sound comfort affects everyone's fatigue but above all it affects the ability to concentrate.
Every blogger, youtuber and video maker knows what their recorded video sounds like if they play it after uploading. The brain naturally filters out unwanted sounds and that's why at first you are not aware of the echoes that arise when you record. The biggest pitfall is large smooth surfaces that are guaranteed to make the room sound like an undesirable soundscape. Ceilings tend to be a major source, but it is not necessary to encase the entire room in acoustic insulation. Not at all. Simply breaking the integrity of a room with a piece of acoustic insulation has a very clear audible effect. Try it out.
