This video describes a situation that unfortunately is very common in housings. Noise is a cause of discomfort and reduces quality of life. 

Not being able to sleep or rest causes a bad mood and decreases performance, concentration, alters personality, leads to health problems, etc. 
Dry construction (with plasterboard + anti-vibration mounts) is the most effective, quick, easy and lowest cost solution. 

The results are evident after soundproofing. Our clients attest to this, they enjoy restful nights and can be calm in their home.
