Audibility characterize the diffusion field is to identify geometric formations and room elements which influence the diffusion properties of the sound field is significantly based on the relationship between objective and subjective parameters. In this study the differences in the characteristics of auditory perception from several workstations with different diffuse nature, which resulted in the conclusion that the geometry and layout of the elements of the room will determine the nature of the distribution of sound in space. In an open office space footprint needed conversation spread evenly to all parts of the room, so that information that is important for all employees can be conveyed properly. The level and nature of the diffusion chamber can be seen from changes in the value of coherence spaces. The space has a higher diffusion properties of the value even higher spatial coherence or similarity of the spread of sound in the higher chamber. Coherence value can be determined by using the Matlab calculations. Coherence value was on every workstation shows that no significant differences from comparison of coherence at all workstations, the highest value of artifacts on workstations 1-4, in the position of the upper left to the lower left on wrokstation 2, with a value of 0.3789, but this value can not be said to be diffuse, because the value of coherence that can be said to have a diffuse condition that is of value 0.5-1, but this condition is spread evenly in the space 9, in other words have a sound spread equally on each workstation. Changes in the diffusion properties of the parameter space is also seen that the acoustic effect, such as C50, T30, and Rasti.
