Assistive Hearing Devices
Amplifying Noise For Patients With Hearing Loss
People with hearing loss may have trouble following a conversation amid considerable background noise, such as a teacher in a classroom setting, a presenter at a conference or an actor in a play. Fortunately, assistive technology can be used to amplify sounds—such as voices—and bring that sound directly into the receiver’s ear.
What Is An Assistive Hearing Device?
Often confused for hearing aids, assistive hearing devices are also called assistive listening devices (ALDs). Like hearing aids, there are several different types of ALDs available. These devices amplify noise in ways that can be particularly beneficial in certain situations when hearing aids can only be so helpful. The devices use systems—either an FM, infrared, inductive loop or Bluetooth system—to amplify sound in the following ways:
Who Can Benefit From Assistive Hearing Devices?
Patients with different degrees of hearing loss can use ALDs, including patients with cochlear implants. They are commonly used in addition to hearing aids and cochlear implants in specific environments, and are difficult for people with hearing loss. However, people can benefit from at-home use of these devices as well.
Types Of Assistive Hearing Devices
All ALDs consist of a microphone that the speaker wears, a device that attaches to the listener and a method of transmission. As the speaker talks, the listener clearly and comfortably hears the speaker’s voice right in their ear.
