The purpose of this project is to compare each sound absorber pad each ratio that has the best absorption and the best strength. Include : Sheet 1 ratio between fiber per Flour water 4 : 0,Sheet 2 ratio between fiber per Flour water 2 : 1,Sheet 3 ratio between fiber per Flour water 3 : 1. By the first experiment is create a simulation of sound absorber pad meeting room with a box and bring sound absorber pad. In each ratio paste than put the speakers plugged into the sound generator and than turn on the machine bring sound meter measured the volume of the sound.
The second experiment is bring sound absorber pad each ratio tie to the poles brind spring scales tie on the other side and pull to lack and write a results. By the result,Sheet 1 ratio between fiber per Flour water 4 : 0 is the best absorption result of volume equals 78.5 dB and sheet 2 ratio between fiber per Flour water 2 : 1 has the best strength by pulling force from the spring scale to 10 N(newton) but sound absorber pad not lack.
