The Most Useful ALD Technology Available Today

Assistive listening devices (ALDs), also acknowledged as assistive listening systems (ALS) are amplifiers that bring sound directly to the ear. These assistive devices can help you communicate better in one-on-one conversations. ALDs separate sounds, most notably speech, from background noise. People with a hearing impairment require a volume increase to achieve the same level of understanding as those without a hearing problem, and an ALD provides this boost in volume without making the sound too loud for everyone else. If you do not use a hearing aid or have a cochlear implant but need an occasional sound boost, an ALD can increase the volume level for you as well.

Multiple Uses

An ALD is appropriate for people with all degrees of hearing loss ranging from mild to profound. Hearing aid users, people with cochlear implants and individuals who use neither a hearing aid or cochlear implant will find an ALD useful. ALDs amplify sound for those without a device and stretch sound for hearing aid and cochlear implant users. ALDs aid listening in three ways:

  • Minimize background noise
  • Reduce the distance between a sound source and the receiver
  • Override poor acoustics

ALDs work well in places of entertainment, workplace, educational settings, and personal use. Here are five ADLs that can improve your listening experience.

Personal Amplifiers

This small box is ideal for one-on-one conversations. These devices allow the person to whom you are speaking to attach a microphone to their clothing while you plug the cord into your amplifier. The result is amplified conversation without background noise. The devices are small and relatively inexpensive.

Infrared Systems

These systems transmit sound via light waves. As the light waves will not penetrate walls, these systems are particularly useful for private situations such as doctor visits and court proceedings. They also work well at theatres and for television viewing.

FM Systems

These ALDs offer mobility. The devices use radio broadcast technology to deliver sounds directly to your ears. This wireless system allows you to hear sounds from up to 150 feet away from the sound source. This system is an excellent choice for educational settings and outdoor activities.


Bluetooth technology enables two devices such as a cell phone and a wireless hearing aid with streamer to communicate with each other. It provides a secure connection without interference and allows a user to switch back and forth between multiple devices.

Induction Loop Systems

This system utilizes an electromagnetic field of insulated wire to transport sound to a user’s ears. Versatile and inexpensive, this mobile system can find use among the non-hearing aid wearers by the use of headphones or a receiver system.

Boost The Volume

If you wear hearing aids and feel like a boost in volume in certain situations is needed, an ALD might be right for you. Even if you do not use a hearing aid or have a cochlear implant, an ALD can increase the volume while you watch TV, attend a class, or enjoy the theatre. Speak with your hearing healthcare professional today to determine if an ALD is right for you.
