The original architectural design of the campus of University City (UC), of the National Autonomous University of Mexico, was successful in its beginnings, in the 1950s. At that time, the conditions of Acoustic Comfort (AC), were not relevant due to its location in a rural area. UC is located south of Mexico City, which is one of the largest metropolises in the world. Urban changes, the demographic explosion, communications, politics and economic resources have had a profound impact on its environment. In this context, even today, the AC is not considered a priority in the architectural design of new buildings within the campus, which are designed and built the same as 70 years ago. This fact has a negative impact on the acoustic conditions of the premises and interferes with the educational, investigative and administrative processes that are carried out on a day-to-day basis. With the aim of improving the AC in university buildings and using standardized equipment, acoustic conditions were investigated, modeled and systematized in the recent Postgraduate Unit of the UC, in order to propose architectural solutions that improve the conditions in the premises, complying with ANSI/ASA recommendations.
