Resumen
El presente trabajo determina los niveles de ruido ambiental en una biblioteca universitaria. Se tomaron mediciones en dos zonas que dividen por completo el interior de las instalaciones de la biblioteca, usando un sonómetro HP 882C. Se registraron nivelesde ruido por encima de los 60 decibeles y máximos cercanos a los 73 cuando la biblioteca estaba en plena capacidad; asimismo, se registraron niveles de ruido entre 5 decibeles hasta un máximo de 68 al encontrarse las instalaciones vacías. Dichos valores resultaron encontrarse fuera del límite recomendado por la Organización Mundial de la Salud (OMS) además, de la Norma Técnica para la Prevención y Control de la Contaminación Ambiental dictada por la Legislación Ecuatoriana. Las principales fuentes de ruidoque se identificaron fueron: teléfonos celulares, equipos de cómputo y acondicionadores de aire; incluyendo a los propios usuarios, debido a que el personal administrativo constantemente les realiza llamados de atención. Se señala como factor crítico la no muy buena calidad acústica en las instalaciones. Para fomentar la cultura bibliotecaria y dar una solución tecnológica al problema, se diseñó un prototipo capaz de medir los niveles de ruido constantemente en las zonas de la biblioteca, para cuando los usuarios sobrepasen el umbral permitido, el dispositivo reproduzca un audio grabado para proceder a realizar el llamado de atención respectivo, sin la necesidad de que el personal administrativo se encuentre presente.
This paper examines ambient noise levels in a university library, taking measurements at two zones that completely divide the interior with the library installation,using aHP 882Csound level meter. Noise levels were recorded above 60 decibels and maximums close to 73 when the library was at full capacity; likewise, noise levels were recorded between 5 decibels to a maximum of 68 when empty facilities were found. These values were found to be outside the limit recommended by the World Health Organization (WHO) also by the Technical Regulations for the Prevention and Control of Environmental Pollution dictated by the Ecuadorian Legislation. The main sources of noise that were identified were: cell phones, computer equipment and air conditioners; including the users themselves, because the administrative staff constantly makes wake-up calls. The not very good acoustic quality in the installations is pointed out as a critical factor. To foster the library culture and provide a technological solution to the problem, a prototype was designed to measure noise levels constantly in the areas of the library, for when the users exceed the allowed threshold, the device plays an audio recording to make the respective wake-up calls, without the need for the administrative staff to be present.
