Assisted Listening Devices or Assistive Listening Device (ALD) helps you hear as well as communicate. You may be wearing hearing aids but there may be times or situations when they is not enough.
Despite hearing aids you could still be having a hard time watching TV, a sports show in a stadium, a tour guide talking, or communication in a situation where lots of people talk at once such as a party. This is where the assisted listening devices also called assistive listening devices (ALD) come into play.
The assisted listening devices work by amplifying foreground sound without affecting the background noise. Perfect for noisy situations, or when a hearing impaired person is standing at a considerable distance from the speaker and in places with poor acoustics.
Types of ALDs
Frequency Modulation (FM) Systems: They can be likened to miniaturized or a personal radio station however it operates on frequencies assigned by the FCC. It allows the speaker’s voice to come to you as if he were speaking in front of you minus the background noise.
They are used in places where a lot of people congregate to do activities such as classrooms, a restaurant, theaters, museums, conference rooms, convention centers to name a few.
Infrared Systems (IR): They are most often used in conjunction with your television and they can also be used in theaters. The IR system transmits the TV signal in light waves into a receiver you have. If you are you looking for more info on prisluskivaci have a look at the page.

Amplified Telephones: Are special types of telephones that cater to the needs of those who are hard of hearing. These phones have features such as volume and tone adjustment, and a high phone memory capacity.
Cochlear Implants: Are electronic devices that are surgically implanted to the person who is hard of hearing. It works giving electrical stimulation to the nerves inside the ear.
Alerting Devices: Are electronic devices that allow those who are hard of hearing and/or deaf to become aware of what is going on in his surroundings. Examples are flashing lights that alert a senior that the house is on fire and the doorbell or the alarm clock is ringing.

If your hard of hearing senior loves to visit museums, loves to watch theater or in general loves to travel, FM Systems are good and if your senior loves to stay at home to watch TV all day then he probably needs Infrared Systems.
