Figure 5 Total freezing episodes (each group is of 6 animals, under the 8 hr noise/day action) in the open field. Therefore after 7, 30 and 60 days of noise action the rats of the 2nd group have had 51,5%, 96,6%, 80% total freezing episodes compared with the 1st group (in which the activity was considered to be as 100%), the rats of the 3rd group spent 59,7%, 110%, 94,6%, and the rats of the 4th group spent 57,8%, 111,5%, 111,5%, respectively
