Ansiedade e depressão geriátricas e seus fatores associados: um estudo comunitário em Vila Nova de Gaia

摘要: BACKGROUND In recent years there has been a rapid growth of installed wind power in Portugal. This, combined with technological development, has led to an exponential growth of wind turbines and their implementation [1]. One of the main concerns regarding the installation of wind farms is the presence of infrasound and the negative impacts they have on health, namely Vibroacoustic Disease (systemic pathology caused by excessive exposure to infrasound being characterized by the existence of damage caused directly in the tissues or organs) and Wind Turbine Syndrome (symptoms related to the organs of the vestibular system, which manifest as sleep disturbances, headaches, ringing in the ear and other symptoms)[2, 3, 4]. OBJECTIVE In this sense and due to the desire to understand the reality of the population exposed to noise from wind farms, this study aimed to analyze and characterize the Infrasound and Low Frequency Noise and Environmental Noise produced by wind turbines, as well as to understand which variables influences the propagation of noise and whether there were variations in propagation taking into account seasonality. METHODS The study was carried out at the Wind Farm of Cela, in Alcobaça, Portugal. The investigation assumed a prospective component with the objective of verifying that environmental variables such as air velocity, temperature and relative humidity could influence the sound pressure level of infrasound at the site. The procedure for data collection was developed in two periods: summer and winter. A sample of 59 measurement points was defined and data were collected using the CESVA …
