[The auditory and neuropsychological effects of school children's exposure to environmental noise in a locality in Bogotá, 2010].

Objective: Evaluating the effect of environmental noise on the auditory health of a group of students from a locality in Bogotá, their educational development and leisure activities and the appearance of neuropsychological symptoms.

Methods: This was an observational cross-sectional prevalence study in a sample of 581, 10-17 year-old children and adolescents in two district educational institutions, defined as higher (>65 dB) and lower exposure (<65 dB) according to an environmental noise map of the locality, such ranking being subsequently verified. A survey was made regarding their health-related background, perception of being exposed to noise and auditory health-related habits; a liminal tone audiometry of the airway was taken using the criteria recommended in the Infrastructure Technical Advisory Group'snoise-induced hearing loss (ITAG-NIHL) guidelines.
