King-Kopetzky syndrome is a clinical condition in which patients often complain of difficulty in listening, especially in noisy environments, and are unable to communicate well with others. The pure-tone hearing threshold is generally within the normal range. It is also referred to as hearing impairment with normal hearing or abnormal hearing function. 5% of patients who present with ear or hearing symptoms have this condition, and about 5-10% of those who present with hearing impairment have this condition. The most common complaint of patients is hearing impairment in noisy environments or during group communication or television viewing, but some studies have shown that patients primarily respond poorly to warning signals such as doorbells and telephone bells. In 2000, Zhao and Stephens found that 58% of the patients had difficulty listening in noisy environments, 56% complained of difficulty in multi-person conversations, 42% complained of difficulty watching television and listening to the radio, 30% had difficulty in general conversation, 21% needed to be repeated, 21% made errors in conversation, 16% had to face others to observe their speech patterns, 13% had difficulty in employment, 11% had difficulties in 13% of patients have difficulty with employment, 11% of patients miss communication, and 10% of patients feel anxious, nervous, or irritable as a result. Patients with King-Kopetzky syndrome are clinically classified into seven categories: 1) middle ear dysfunction; 2) mild cochlear pathology; 3) abnormalities of the olive cochlear bundle efferent system; 4) purely psychiatric factors; 5) multifactorial auditory pathology; 6) a combination of auditory and psychiatric factors; and 7) unknown factors. From this classification, it is easy to find that the etiology of King- Kopetzky syndrome patients is diverse and uncertain. Diagnosis 1, pure tone hearing threshold: Zhao et al. found that the pure tone results of these patients showed that their mean hearing threshold was 6.5±5.2 dB, which was higher than that of the control group. 2.Acoustic conductance: the acoustic reflex threshold was increased 3.Otoacoustic emission: Zhao et al. showed that TEOAE and DPOAE were abnormal. 4. Central function examination: speech recognition rate, assessment of event-related potentials. 5.Examination of medical history and family history Psychology Diagnostic criteria 1.Patients are seen for auditory disorders, especially complaints of difficulty in understanding speech in noisy environments. 2.No clear causative factors, such as central pathology, ototoxic drug intake and occupational noise exposure. 3, Otolaryngological examination failed to detect conductive hearing impairment.
