Objective: To analyze the audio files of vascular tinnitus recorded through the ear canal, verify the function of the self-developed objective tinnitus detector, and propose a detection scheme for vascular tinnitus through the ear canal. Method: A self-developed objective tinnitus detector was used to detect and record tinnitus audio through the ear canal in 20 volunteers clinically diagnosed with vascular tinnitus. The data recognized by the patients was replayed to determine effective audio, and the audio characteristics were analyzed through software. Result： a total of 20 volunteers with vascular tinnitus were detected, all of whom were able to capture audio files through the external ear canal probe. Among them, 17 patients were confirmed by replaying the audio. Conclusion: Our developed objective tinnitus detector can capture the audio of most objective tinnitus through a high-sensitivity probe placed in the external ear canal, which is a new objective tinnitus detection scheme; Vascular tinnitus has typical rhythmic characteristics, and our equipment is still unable to accurately distinguish arterial and venous tinnitus.
