Behind-the-Ear Hearing Aid Diagram | How BTE Hearing Aids Work #3349502 (License: Personal Use)

This medical illustration depicts a standard behind-the-ear (BTE) hearing aid, featuring a light-blue casing that rests behind the auricle, connected via a thin transparent tube to a custom earmold seated in the ear canal. The receiver (speaker) is housed within the earmold, delivering amplified sound directly into the auditory canal. The design emphasizes comfort, adjustability, and suitability for moderate to severe hearing loss.

Used on audiology clinic websites, hearing aid product pages, patient education materials, and telehealth resources to explain BTE hearing aid anatomy and fitting. Matches user intent for understanding device types, comparing hearing aid styles, or preparing for a hearing consultation.
