Figure 4 The time in the periphery zone after 7, 30 and 60 days (each group is of 6 animals, under the 8 hr noise/day action). Thus, after 7, 30 and 60 days of noise action the rats of the 2nd group have 108,4%, 110%, 110% time in the periphery zone compared with the 1st group (in which the activity was considered to be as 100%), the rats of the 3rd group spent 107,3%, 108,5%, 105%, and the rats of the 4th group spent 108%, 108%, 104,2% respectively
