Assistive Listening Devices (ALDs) help people hear better in specific situations, like in a crowded room or while watching TV. They are helpful for people who find it hard to hear even with hearing aids. ALDs can make sounds clearer by reducing background noise and amplifying the important sounds you want to hear.

Overview of ALDs

ALDs work differently than hearing aids. They focus on delivering sound directly from the source to your ears, making it easier to hear speech or music. They are often used in public places like theaters, classrooms, or churches, where background noise can be a problem. Some devices can be used with hearing aids or cochlear implants, while others can be used on their own.

Assistive Listening Devices VS Hearing Aids

While both ALDs and hearing aids help people hear better, they are different tools. Here are their differences and similarities:

Similarities:

  • Both assistive listening devices (ALDs) and hearing aids are designed to help people hear better.
  • Both can improve sound clarity and make it easier to hear speech in various environments.

Differences:

  • Hearing Aids:
    • Worn all day to amplify all sounds around the user.
    • Customized to fit the user’s specific hearing loss needs.
  • Assistive Listening Devices (ALDs):
    • Used only in specific situations, such as noisy environments or large spaces.
    • Provide extra support when hearing aids are not sufficient.
    • Can be used by anyone needing additional help, regardless of whether they wear hearing aids.

Types of Assistive Listening Devices

Audio Induction or Hearing Loop

This system uses a loop of wire placed around a room or worn around the neck to send sound directly to hearing aids or cochlear implants with a T-coil. It provides clear sound without background noise and is commonly used in public spaces like theaters and churches. Pros include reduced background noise and effective use in large spaces, while cons involve needing a T-coil in hearing aids and being limited to places with loop systems.

Infrared System

An infrared system uses light waves to send sound from a transmitter to a receiver worn by the user. It is great for watching TV or in areas where privacy is essential, like courtrooms. The system is commonly used in homes, theaters, and public meeting rooms. It provides clear sound and does not interfere with other electronics but requires a direct line of sight and is only suitable for indoor use.

FM System

FM systems use radio signals to transmit sound from a microphone or transmitter to a receiver worn by the user. These systems are helpful in noisy environments or over long distances, like in classrooms or public lectures. They provide clear sound and can be used indoors or outdoors, but may experience interference from other radio devices.

Personal Amplified System

Personal amplified systems are small, portable devices with a microphone and earphones that amplify sound. They are easy to carry, affordable, and can be used in various settings like at home or in small group settings. While these systems are simple and portable, they also amplify all sounds, including background noise, which can be a drawback in certain situations.

Assistive Listening Devices FAQs

What is the most commonly used assistive listening device?

The most commonly used ALD is the hearing loop system. It is popular because it reduces background noise and delivers clear sound directly to the user’s hearing aids or cochlear implants with a T-coil.

Why are assistive listening devices necessary?

ALDs are necessary because they provide extra help in situations where hearing aids alone might not be enough. They help people hear better in places with lots of background noise or where sounds are far away, like theaters or lecture halls.

Can assistive listening devices take the place of hearing aids?

No, ALDs cannot replace hearing aids. Hearing aids are designed to be worn all day and help with everyday sounds. ALDs are used for specific situations, like when you need extra help hearing in a noisy environment or at a distance.
