Assistive Listening Devices (ALDs)
Assistive Listening Devices (ALDs) are additional devices designed to complement modern hearing aids by addressing specific communication needs that hearing aids alone may not fully resolve. These situations may include difficulties with telephones, radios, televisions, and hearing essential sounds like door chimes, phone bells, and alarm clocks. ALDs have been developed to cater to these challenges, enhancing sound amplification without increasing background noise.
Assistive Listening Devices are specialized tools that amplify desired sounds (such as voices, music, or public announcements) while minimizing background noise. Unlike hearing aids that amplify all sounds in the environment, ALDs focus on specific sounds through strategically placed microphones.
Additionally, ALDs are beneficial for individuals with various degrees and types of hearing loss, including those with normal hearing. Some ALDs are used alongside hearing aids, while others can be used independently.
Types of ALDs:
- Personal Amplifiers: Portable devices with a microphone and amplifier, ideal for one-on-one conversations.
- FM Systems: Utilize FM radio spectrum to transmit sounds, beneficial for localized areas and complex situations.
- Infrared ALDs: Use light wave spectrum for sound transmission, providing privacy but susceptible to sunlight interference.
- Induction Loop Systems: Create electromagnetic fields for amplified sound delivery, versatile and common in public spaces.
- Personal Listening Systems: Designed to minimize environmental noises and carry sound directly to the listener, suitable for various settings.
- TV Listening Systems: Enable clear TV, radio, or stereo listening without high volumes or background noise interference.
- Direct Audio Input Hearing Aids: Connect directly to TV, stereo, or other devices, improving sound quality and reducing feedback.
- Telephone Amplifying Devices: Enhance phone compatibility with hearing aids through T-coil connections, reducing background noise.
- Cell Phones: Compatible with most hearing aids but require consideration for digital compatibility to avoid noise or distortion.
- Remote Microphones (RM): Remote Microphones are wireless devices placed near the speaker to transmit speech directly to hearing aids or cochlear implants. They enhance speech recognition in noise, reduce distance-related challenges, and support language learning, especially for children.
- Hands-Free Systems: For maximum benefit, hearing-impaired users can opt for binaural hands-free systems, providing enhanced clarity and convenience in various activities.
If you’re considering an ALD or RM system, consult your audiologist for guidance on the most suitable options for your specific needs and preferences.
