[A descriptive study of hearing in children].

The authors made an audiological screening of the entire population of the Valle de los Pedroches entering primary education in 1992. The auditory levels of the children were measured and abnormalities were detected. In a total of 440 children, 43 hypoacusic cases were found. The type of hypoacusis was predominanthy conductive (95.4%), serous otitis media, being the most common cause of hypoacusis in infancy. We deduce that screening is useful for detecting this medical problem.
