发明名称 Hearing aid with portion thereof inserted in auditory canal, with auditory canal ventilation
摘要 A hearing aid device to be worn in the ear or a hearing aid device with otoplastic to be worn in the ear, has at least two aeration channels in combination with flow resistances arranged in the aeration channels that promote a flow from the enclosed auditory canal volume toward the outside in at least one aeration channel and a flow into the enclosed auditory canal volume in at least one other aeration channel. A flow through the enclosed auditory canal volume results therefrom, so that an air exchange ensues. This improves the wearing comfort of the hearing aid device and contributes to the prevention of diseases caused by a poor ventilation of the auditory canal.
