For those who are in the market for a hearing aid, there are many types recommended by specialists. These hearing styles can be based on a number of factors such as hearing loss, budget, lifestyle needs, and aesthetic preferences. No matter what you ultimately choose, it will likely be one of two basic types. Most receiver-in-the-canal (RIC) and behind-the-ear (BTE) styles come in different varieties of metallic finishes and colors to complement the skin tone or hair color. Invisibility and individual results may differ based on the anatomy of the ear. Hearing aids are typically classified into four main categories:
- In-The-Ear (ITE’s): This category has a wide range of sizes from the Full Shell which fills the Concha completely, gets smaller gradually to Hal Shells down in the canal CIC’s completely and finally fits deep or looks invisible in The Canal.
- RITE’s/RIC’s: These are the enhanced version of the old BTE’s and are among the most popular fitting selections because of the wearer’s comfort and product’s cosmetic appeal. The latest of this genre use a small size electric wire to send an acoustic signal directly to the speaker unit of ear canal using either the custom made tip or soft dome.
- BTE’s: These are one of the first units produced widely and traditional face of a hearing aid. They are still capable of providing the greatest power output. These are fitted behind the ear and utilizes a sound tube to deliver the amplified sound to the canal.
- Specialist: These include Air/Bone Conduction glasses which is an alternative option for sound delivery, Cross and Bi-Cross for asymmetrical or single-sided hearing problems, and the Bone Conduction Aids are used when sound delivery/ air conduction is not feasible.
