• Autophone — A medical apparatus or device used for magnifying sounds and improving hearing in hard-of-hearing individuals; a hearing aid. As an adjective or in an extended acoustic sense, the term describes an acoustic system capable of adjusting its sound reception parameters based on its own echo or vibrations.
• Autophony — An unpleasant clinical symptom characterized by the abnormal, highly intense, and magnified perception of one's own voice, breathing, or internal body sounds inside the affected ear. This phenomenon occurs most frequently due to Eustachian tube dysfunction, specifically a patulous Eustachian tube, or severe middle ear congestion.
• Autophonomania — A historical psychiatric term or extremely rare clinical neologism used to describe an obsessive, impulsive tendency or a morbid urge toward suicide or severe self-harm. In classic treatises on mental alienation, it represented a specific form of mania where melancholic delusion or psychotic depression focuses exclusively on the destruction of one's own organism.
