Patent number: 11418900Abstract: A tinnitus treatment device may include a sound generation unit configured to generate an electrical stimulus, and an open earphone operably coupled to the sound generation unit to produce acoustic vibrations based on the electrical stimulus. The open earphone may include an auditory passage and the open earphone may be insertable into an ear canal of a person such that the auditory passage enables sound to pass substantially unobstructed by the device into the ear canal of the person. The sound generation unit may be configured to be adjustable to tune the electrical stimulus based on a characteristic of tinnitus symptoms experienced by the person.Type: GrantFiled: July 9, 2019Date of Patent: August 16, 2022Assignee: The Johns Hopkins UniversityInventors: Dawnielle Farrar-Gaines, Bradford J.
