Abstract

Hearing impairment is a specific difficulty in perceiving the sounds of the environment through hearing, as it is a prevalent condition that affects about 5% of the world's population. According to the World Health Organization (WHO), it ranks third among the pathologies, which involve years of life with disabilities (YLDs), which implies the need for the implementation of effective treatments, in order to improve the quality of life of people who suffer from it (Díaz, Goycoolea, Cardemil, 2016). Hearing impairment alters the capacity for the reception, discrimination, association and understanding of sounds, both from the environment, and the sounds that make up an audio-vocal linguistic code such as Spanish. Hearing impairments are classified according to the location of the lesion in conductive, sensorineural or mixed losses; degree is severe in mild, moderate, severe, deep or cofotic (deafness) and age of appearance in prelinguistic and postlinguistic.
