Two patients with auditory hallucinations beginning after a long history of progressive bilateral hearing loss were studied. The hallucinations included both unformed (tinnitus and irregular sounds of varying pitch and timbre) and formed (instrumental music, singing and voices) components, and were repetitive. They were affected by ambient noise levels; their content and speed were influenced by attentional and intentional factors. There was no evidence of global dementia, nor of epileptogenic or psychiatric disturbance. A combination of peripheral and associated central "disinhibition" may be responsible for the occurrence of such hallucinations.
对两名患者进行了研究，他们在长期渐进性双侧听力丧失后开始出现幻听。幻听包括未成形的（耳鸣以及音高和音色各异的不规则声音）和成形的（器乐、歌声和人声）成分，且具有重复性。它们受环境噪音水平影响；其内容和速度受注意力和意向因素影响。没有全面性痴呆的证据，也没有癫痫源性或精神障碍的证据。外周和相关中枢的“去抑制”相结合可能是此类幻听发生的原因。
