Types of Hearing Aids
Types of Hearing Aids
Hearing aids have come a long way from the proverbial ear trumpet. You now have choices that range from completely invisible in the ear hearing aids to the conventional over the ear hearing devices. The number of options is almost overwhelming, which is why we’re providing you an overview here.
Ultimately which type of hearing aid you buy depends on your hearing needs and your lifestyle. The best way to select the right one of the hundreds of hearing aids available today is to get guidance from your local hearing experts.
Don't Wait
The Newest Hearing Aids
The digital revolution has made a huge impact on the way hearing aids look, feel and function. They can be so small that they are virtually invisible, so “cool” looking that you will want everyone to see them and so natural sounding, they mimic the way you used to hear before you experienced hearing loss.
It’s no secret why digital hearing aids account for most hearing aids sold today. The quality of sound is amazing. Once you try a pair, you’ll see why they’re often the best choice.
Which Type of Hearing Aid Is Right for You?
No one wants hearing aids that makes them look like they have an appliance strapped to their head. Seriously, our patients tell us they don’t want anyone to notice their hearing aids. They want hearing aids that work well but are discreet.
Below we review the primary styles along with our recommendations:
Are Assistive Listening Devices the Solution?
Assistive Listening Devices (ALDs)
Augmentative and Alternative Communication Devices (AAC)
Alerting Devices
Assistive listening devices typically use a microphone to capture an audio source near its origin and broadcast it wirelessly to over an FM (Frequency Modulation) transmission, IR (Infra Red) transmission, IL (Induction Loop) transmission, or other transmission method.
FM systems use radio signals to transmit amplified sounds up to 300 feet. That makes them useful in many public places, such as classrooms, where the instructor wears a small microphone connected to a transmitter, and the student listens via a worn receiver, which is tuned to a specific frequency or channel.
Infrared systems use infrared light to transmit sound. Unlike induction loop or FM systems, the infrared system's signal cannot pass through walls, making it particularly useful in courtrooms, where confidential information is often discussed, and in buildings where competing signals can be a problem, such as classrooms or movie theaters. However, infrared systems cannot be used in environments with too many competing light sources, such as outdoors or in strongly lit rooms.
Personal amplifiers are useful in places where the above systems are unavailable or when watching TV, being outdoors, or traveling in a car. About the size of a cell phone, these devices increase sound levels and reduce background noise for a listener. Some have directional microphones that can be angled toward a speaker or other source of sound. As with other ALDs, the amplified sound can be picked up by a receiver that the listener is wearing, either as a headset or as earbuds.
