Among the following, what is a common assessment used for diagnosing hearing impairments?

A medical history review is integral to diagnosing hearing impairments, as it provides a comprehensive understanding of the individual's previous health conditions that may contribute to hearing loss. This review includes examining any past illnesses, genetic predispositions, and environmental factors that could affect auditory function.

While other assessments like behavioral observation can offer insights into a child's responses to sound and possible hearing issues, these methods do not provide the same level of detail regarding the underlying health history that may contribute to hearing impairments. Standard intelligence testing primarily measures cognitive abilities and does not assess auditory processing or hearing function. Parental interviews alone, without the context of a thorough medical history, may miss critical information regarding the child's health background. Thus, reviewing medical history stands out as a foundational step in identifying and diagnosing hearing impairments accurately.
