Which term denotes hearing deficits with no identifiable anatomical cause?

The term that denotes hearing deficits with no identifiable anatomical cause is classified as "nonorganic." This term encompasses a variety of hearing impairments that cannot be attributed to any physical damage or anatomical abnormalities in the auditory system. Instead, these deficits may arise from psychological factors or may be reported by the patient without a corresponding physiological condition.

In audiology, it is essential to distinguish between organic and nonorganic hearing losses, as this can have implications for diagnosis and treatment. Nonorganic hearing loss could occur for several reasons, including malingering, conversion disorder, or other psychological factors affecting perception.

The other options, while related to specific aspects of hearing loss, do not accurately capture the broad category of hearing deficits that are not associated with any identifiable anatomical issue. For example, pseudohypacusis typically refers to a situation where a person exaggerates or feigns hearing loss, while functional may imply some psychological aspect but does not specifically refer to the absence of an identifiable cause. Erroneous, in this context, does not provide a recognized terminology within audiological terminology to define the nature of the hearing loss.
