Behind the Ear (BTE): Target Hearing Loss is moderate to Profound This hearing aid fits over and behind the ear. The sound from the hearing aid is delivered to the ear via tubing and an earmold. BTE hearing aids can be used to fit most hearing losses, however they are used mainly to fit severe to profound hearing losses.
	Open Fit BTE: Target Hearing Loss is high frequency This hearing aid fits over and behind the ear. The sound from the hearing aid is delivered to the ear via tubing and an earmold. BTE hearing aids can be used to fit most hearing losses, however they are used mainly to fit severe to profound hearing losses.
	In the Ear (ITE): Target Hearing Loss is mild to moderately severe This hearing aid fits in the ear and fills it up completely. ITE's are very versatile and are used to fit a variety of hearing losses from mild to severe.
	In the Canal (ITC): Target Hearing Loss is mild to moderately severe This hearing aid fits in the ear but only fills up a small part of the ear. Being smaller they have less power then BTE and ITE's. Thus they are not typically used for severe and profound hearing losses.
	Completely in the Canal (CIC): Target Hearing Loss is mild to moderate This is the smallest hearing aid available. They fit all the way into the ear canal and are virtually invisible to others. Due to their small size they are the least powerful and not suited to all hearing losses and patient needs.
