Hearing aids: types and technology
Hearing loss can be a challenging experience, but with advances in technology, the options for managing it have expanded greatly. Today, hearing aids come in various shapes, sizes, and styles, and utilize a wide range of sophisticated technologies. This can be confusing for people facing a hearing aid for the first time or those looking to upgrade their existing device. In this article, we will discuss the various types of technology used in hearing aids, to help you make an informed decision about which type is right for you.
Analogue hearing aids are the oldest type of hearing aid technology, and are still available today. They work by amplifying sounds from the environment and passing it directly to the ear. Analogue hearing aids are straightforward and simple, but their performance can be impacted by background noise and their frequency response can be limited. Several brands of ‘over the counter’ hearing aids which can be purchased on-line are using this as a cheaper and disposable technology. Some safety concerns with over amplification have been raised with these products and health standards and regulators are investigating ways to raise public awareness.
Digital hearing aids are the most advanced type of hearing aid technology, and the most popular choice for people with hearing loss. Digital hearing aids convert sound into digital signals that are processed within the device, allowing for a more customisable and precise amplification experience. Digital hearing aids offer various features, such as noise reduction, directional microphones, and automatic adjustments based on the environment.
There are several styles of hearing aids available but a number of manufacturers, each designed to meet the specific needs of the individual. Some of the most common types include:
In-the-Ear (ITE) Hearing Aids: In-the-ear hearing aids are custom-made devices that are molded to fit snugly inside the outer ear. They are available in both analogue and digital versions and can be a great option for those with mild to moderate hearing loss. ITE hearing aids are discreet and easy to use, and because they sit directly in the ear canal, they can offer a high degree of sound clarity.
Behind-the-Ear (BTE) Hearing Aids: Behind-the-ear hearing aids are the most common type of hearing aids and are suitable for people with mild to severe hearing loss. BTE hearing aids consist of a small plastic case that sits behind the ear and a custom-made earmold that fits inside the ear canal. BTE hearing aids are available in both analog and digital versions and can be adjusted for different degrees of hearing loss.
Completely-in-the-Canal (CITC) Hearing Aids: Completely-in-the-canal hearing aids are custom-made devices that are designed to fit deep inside the ear canal. They are suitable for people with mild to moderate hearing loss, and are one of the most discreet types of hearing aids available. CIC hearing aids are also easy to use, and because they sit directly in the ear canal, they can offer a high degree of sound clarity.
Hearing aids have come a long way in recent years, with new technologies and designs offering a wider range of options for people with hearing loss. Your Audiologist will work with you to choose the right type of hearing aid.
