RODRIGUEZ CISNEROS, Yeny  e  BALDEON QUISPE, Wilfredo. Noise and acoustic confort evaluation at the National Agriculture Library. Lima, Peru. Med. segur. trab. [online]. 2018, vol.64, n.250, pp.17-32. ISSN 1989-7790.

The National Agricultural Library (BAN) is the leading library in agricultural and livestock issue of Peru. It provides services in nine reading rooms in two buildings. Evaluations of the perception and the acoustic comfort in reading rooms, as those of a library, had not been carried out up until now. As libraries are known for being one of the principal tools for professional development, it was considered to evaluate the perception of the environmental noise, to determine its noise levels and the acoustic comfort in the BAN. For this purpose, 359 BAN users were polled, noise levels were measured and acoustic comfort was determined following the methodology established by INDECOPI1 (National Institute for the Defense of Free Competition and the Protection of Intellectual Property) and INSHT (National Institute for Safety and Health at Work)2 respectively. It was found that 65,9% of BAN users perceive study rooms as «quiet» and 70,2% indicate that the sound environment is «comfortable». The noise levels ranged from 44,1 to 54,2 dBA. Concerning the acoustic comfort, it was established that the Sciences, Newspaper and Periodicals Library, References, Social Sciences, Agriculture and Thesis rooms are comfortable. However, the results are not accurate for the whole BAN, as significant differences between PPDn-objective and PPDn-subjective. were found.
