443):Īlthough ultrasonics has been employed for most of the twentieth century, the tempo of new and improved applications has reached virtually explosive proportions only in the past few years (Raichel, 2006: p. For Pedersen (2008) “ The human hearing at low-frequencies is a research area, where the knowledge is still quite limited.” (Pedersen, 2008: p. In fact, researches with infrasound, ultrasounds and low frequency sounds are recent in several aspects. Currently, studies show that low frequency can influence physical and mental health in varied ways (Ferreira et al., 2006 Pedersen, 2008 Broner, 2011 Nohama & Silvério-Lopes, 2009 Venslauskas, Ostasevicius, & Vilkinis, 2017). Solutions to problems of this nature have been objects of research and essential aspects for technological improvements in diverse continents since the beginning of the 20 th century, a fact observable mainly by the emergency of institutions dedicated to the subject, such as the Acoustical Society of America (ASA) 1, International Commission for Acoustics (ICA) 2, Deutsche Gesellschaft für Akustik (DEGA) 3, Société Française d’Acoustique (SFA) 4, European Acoustics Association (EAA) 5, Institute of Acoustics (IoA) 6, Brazilian Society of Acoustic (SOBRAC) 7, etc.īy the end of 1970s, Broner (1978), in a publication in the Journal of Sound and Vibration, had already addressed the issue of low frequency noise (LFN) 8 as a topic of growing interest in the society at the time. It is concluded that the architectural and acoustic-structural aspects of projects related to classrooms and school structures need alterations that permit better quality of life for professionals and students, appropriated conditions for the educational process and improvement of academic performance.ĭiverse societies across the globe have faced problems related to acoustics in different aspects. The results suggest pedagogical losses in the sense of insufficient school development, possibilities of health problems besides irreparable hearing loss, aspects incompatibles with cognitive activities, improvement of the quality of life and educational development. The methodology is based on bibliographic analyses and acoustic evaluate of academic environments. It pretends to call attention to the fact that diverse inappropriate acoustic-structural aspect of classrooms and academic environments can generate damage to the educational process and health. It presents partial results of a research project about acoustic-structural influences on Brazilian education based in the analysis of Campus I of the Federal University of Paraíba (UFPB) in 2016 beyond literature related to the theme in other Brazilian states.
