A behind the ear (BTE) Hearing aid is an auditory amplification device that fits behind the ear. The device's three parts include an earmold, case and tube. The ear mold is typically sculpted to fit the wearer’s ear or made of highly-flexible material that can be easily manipulated into a comfortable shape for any size or shape of ear. The amplifier for the device is inside the case, and the tube connects the amplifier to the earmold. This type of hearing aid is normally recommended to people with hearing losses ranging from mild to extreme.
Depending on the style of the BTE hearing aid, the sound may be transmitted either acoustically or electronically. Options for the colored parts of the hearing aid vary. Some brands offer several skin tones designed to be discreet and barely noticeable, while others provide customers choices of brilliantly-colored devices and an array of creative adornments.
