[Objective tinnitus].

Objective tinnitus is a known but rare otologic symptom. This is a case report about a six-year-old boy, who was referred to a hearing clinic for further investigation of an audible clicking sound. He experienced clicking sounds, and his parents were able to hear the sounds when listening nearby. This objective tinnitus is caused by myoclonus of either the m. tensor tympani or the m. stapedius. We discuss methods to evaluate objective tinnitus including the clinical use of a stethoscope and also the possibility of using impedance measuring in patients with objective tinnitus.
