To completely dissolve the sound, only sound insulation, other methods to dissolve the sound, mostly just psychological comfort, can receive much effect? It is doubtful.
In addition to using Feng Shui array to relieve suffocation, we should also pay attention to closing the windows as much as possible, or choose thicker glass with better sound insulation effect, or even install double glass. Although the cost of installing high-quality doors, windows and carriages is high, it is definitely worth it if it can really isolate the sound. If the external noise only exists for a short time (for example, there is an ongoing project nearby), wearing a pair of earplugs is also a feasible method.
