increases to 55 dB (A) the speech recognition has become difficult, and when it reaches 65 dB (A) a higher vocal effort is required. The necessary reductions in the daytime period in order to reach both the comfortable and the acceptable levels for theses environments to meet the standard, respectively, would be: in the Department of Communication, point I, 24.69 dB(A) and 19.69 dB(A); point J, 21.79 dB(A) and 16.79 dB(A). In the Audio/Video Room, point G, 35.24 dB (A) and 25.24 dB(A); point H, 27.98 dB(A) and 17.98 dB(A); point I, 24.69 dB(A) and 14.69 dB(A); point J, 21.79 dB(A) and 11.79 dB(A). For the night time period, the reductions to reach both the comfortable and acceptable levels would be: Department of Communication, point I, 23.20 dB(A) and 18.20 dB(A); point J, 19.39 dB(A) and 14.39 dB(A). In the Audio/Video Room, point G, 35.04 dB(A) and 25.04 dB(A), point H, 27.81 dB(A) and 17.81 dB(A); point I, 23.20 dB(A) and 13.20 dB(A); point J, 19.39 dB(A) and 9.39 dB(A). Conclusion In order to measure the actual noise level from environments of the EACF the internal measurement of their rooms would be required, which was expected to occur in the summer of 2012/2013. However, on 25 February, 2012, a fire destroyed part of the EACF, creating discontinuity of all the studies. Thus, the data obtained and measured will serve mainly to aid in the preparation of the Reference Term that will guide the construction of new buildings that will comprise the EACF, standing out as desirable the need for more research regarding the sealing materials of environments and their contribution to isolation of the sources of noise, whether outdoors or indoors. The application of questionnaires to users for subjective assessing of the noise that points out psychological changes, as well as physical evaluations to verify the hearing thresholds of the users and the time of exposure to noises with the aid of professionals from other fields of science also would complement this research. In environments directly analyzed, namely Carpentry and Screening Room, the mean noise levels showed differences with the standards parameters; thus, in the future specific solutions should be applied to reduce the noise. In these cases the options are: to reduce the noise at source, to diminish the noise in the environment where the source is located, to decrease the noise between the environment where it is produced and the other environment, or to minimize the noise at the own hearing organ. In environments indirectly analyzed, namely Cabins, Ward, Department of Communication, Library, Laboratories, and Audio/Video Room, further research of construction materials is recommended to achieve the correct measurement of indoor noise level. Acoustic mapping is an important tool that can help in design decisions such as the location of noisy equipment, specification of less noisy equipment, use of materials with acoustic qualities and use of materials that do not require maintenance with noisy equipment.
