Abstract
International standards define normal hearing threshold levels (HTLs) and many studies describe speech recognition in noise (SRN) for adults. Less has been published on these characteristics for children. This study aims to establish ranges of HTLs and SRN for otologically normal 7-year-olds. Air conduction HTLs were measured in 189 7-year-olds within an audiometric booth. Speech recognition was measured adaptively for BKB sentences in noise presented binaurally through headphones, determining the speech-to-noise ratio (SNR) required to score 71% correct. The mean HTLs of otologically normal 7-year-olds were significantly lower (better) than those published for young adults at 1 and 2 kHz. Speech recognition in noise was unrelated to HTLs and was higher (worse) for 7-year-olds (SNR = − 4 dB) than has been found for young otologically normal adults (SNR = − 6 dB). It is concluded that although the HTLs of 7-year-old children are generally better than those of young adults, their speech recognition in noise is worse. This confirms that their ability to recognise speech in noise is not fully developed at this age.

Sumario
Los estándares internacionales definen los niveles de audición normal (HTL) y muchos estudios describen el reconocimiento del lenguaje en ruido (SRN) para adultos. Poco se ha publicado sobre estas características en niños. Este estudio trata de establecer rangos de HTL y SRN para niños de 7 años otológicamente sanos. Se determinó la conducción aérea en 189 niños de 7 años en una cabina audiométrica. El reconocimiento del lenguaje se midió adaptando las oraciones BKB en ruido, presentadas binauralmente a través de audífonos y determinando se determinó la relación señal/ruido (SRN) requerida para obtener un 71%. correcto. El promedio HTL de los niños de 7 años otológicamente sanos fue significativamente menor (mejor) que el publicado para adultos jóvenes a 1 y 2kHz. El reconocimiento del lenguaje en ruido no se relacionó con el HTL y fue mayor (peor) para los niños de 7 años (SNR0-4dB) que el encontrado para adultos jóvenes otologicamente normales (SNR = − 6dB). Se concluye que aunque el HTL de los niños de 7 años es mejor en general que el de los adultos jóvenes, su reconocimiento del lenguaje en ruido es peor. Esto confirma que su habilidad para reconocer el lenguaje no está totalmente desarrollada a esta edad.
