Guideline for sound insulation performance
When one unit of TK-3000 is used against a loud piano sound of 100dB(A), the noise will be reduced to 60dB(A) which is equivalent to a quiet conversation or quiet automobile. Note that the performance varies by types of walls surrounding the room. Please see the following chart.
