Which definition refers to a hearing loss that is intentionally produced or feigned?

The definition that refers to a hearing loss that is intentionally produced or feigned is indeed malingered hearing loss. Malingering is when an individual exaggerates or fabricates their symptoms, often for a specific gain, such as financial compensation, avoidance of responsibilities, or other personal benefits. This behavior is characterized by an apparent lack of consistency in the hearing loss presentation and clinical testing results.

While terms like psychogenic and functional may relate to hearing issues resulting from psychological factors or conditions that do not have a purely physiological origin, they do not specifically denote the intention to deceive or fabricate symptoms for gain. Pseudohypacusis also refers to a form of false hearing loss but is generally understood as an umbrella term for various forms of nonorganic hearing loss, which can include malingering but is not limited to it. Thus, while both terms may overlap, malingered hearing loss specifically highlights the conscious effort to misrepresent one's hearing ability.
