What is the term for hearing loss that occurs during the development of speech and language, between 2-4 years old?

The terminology related to hearing loss during the critical period of speech and language development is crucial for understanding its implications on communication skills. The correct term for hearing loss that occurs during the developmental phase when speech and language skills are acquiring—specifically between the ages of 2-4 years—is "perilingual."

Perilingual hearing loss refers to the onset of hearing impairment occurring while a child is in the process of learning language. This time frame is vital because children are particularly sensitive to auditory input during these formative years, which directly influences their ability to develop essential communication skills.

On the other hand, prelingual refers to hearing loss that occurs before the onset of speech and language development, while postlingual pertains to hearing loss that happens after the establishment of these skills. Postdevelopmental is not a standard term used in this context, which may contribute to confusion without a clear definition.

Understanding these distinctions is important for music therapists and other professionals as they design interventions that accommodate a child’s specific auditory experiences and developmental needs.
