Pseudohypacusis is the term used for a non-organic or functional hearing loss. The mainstay of diagnosis is a lack of consistency in audiological testing. It is usually easier to diagnose in children than in adults, as children are less able to reproduce consistently erroneous results on repeated testing. Nevertheless, the diagnosis is often missed in children, probably due to a lack of awareness of the condition. In a previous study from our department, we highlighted the usefulness of speech audiometry in establishing the diagnosis. However, with the advent of otoacoustic emissions testing, we have changed the emphasis of our testing protocol. Using otoacoustic emissions, the diagnosis of pseudohypacusis can be established quickly and easily.
伪听力减退是用于描述非器质性或功能性听力损失的术语。诊断的主要依据是听力测试结果缺乏一致性。通常儿童比成人更容易诊断，因为儿童在重复测试中较难始终如一地给出错误结果。然而，儿童中这种诊断常常被漏诊，可能是由于对该病症缺乏认识。在我们科室之前的一项研究中，我们强调了言语测听在确立诊断方面的作用。然而，随着耳声发射测试的出现，我们改变了测试方案的重点。使用耳声发射，可以快速、轻松地确立伪听力减退的诊断。
