Measure Noise value at radius around cubicle using MATLAB

1. Create a noise source of 85dB and above inside a cubicle.
2. Let the noise source be centralise placed inside the cubicle of dimension 200cm × 300cm.
3. Noise source to be at the center of the cubicle, and the then simulate and measure what noise value will be at a particular radius around the cubicle e.g 1m, 2m, 3m, 4m, 5m from the cubicle to note the value to be obtain.
4. The materials for the cubicle should be of wood, and plastic, but metal and fibrics.
5. Thickness of material is 20mm which is equal to 2cm.
