Recently launched digital wireless hearing aid applying this new technology can communicate from the hearing instrument to personal computer, phones, Wi-Fi, alert systems, and ALDs via iPhone, iPad, and iPod. One is near-field magnetic induction combined with Bluetooth radio frequency (RF) transmission or proprietary RF transmission and the other is proprietary RF transmission alone. There are two technology solutions for digital wireless hearing instruments improving SNR and convenience. Further development of digital wireless technology in hearing instruments will make possible direct communication with ALDs without any accessories in the near future. The seven types of ALDs are introduced including hardwire devices, FM sound system, infra-red sound system, induction loop system, telephone listening devices, television, and alert/alarm system. They usually use microphones to capture an audio source and broadcast it wirelessly over a frequency modulation (FM), infra-red, induction loop, or other transmission techniques. ALDs vary in their internal electronic mechanisms ranging from simple hard-wire microphone-amplifier units to more sophisticated broadcasting systems. There are many types of ALDs to overcome a triangle of speech to noise ratio (SNR) problems, noise, distance, and reverberation. Prices and promo codes are subject to change without notice.Assistive listening devices (ALDs) refer to various types of amplification equipment designed to improve the communication of individuals with hard of hearing to enhance the accessibility to speech signal when individual hearing instruments are not sufficient.

ZVOX AccuVoice Speakers Assistive Listening DevicesĪll current ZVOX sound systems include our AccuVoice technology that assists your ability to understand dialogue, even at low volume levels. The two primary benefits of Assistive Listening Device speakers are: 1) everyone in the room benefits from the improved sound quality and voice clarity and 2) they avoid the "ear fatigue" often brought on by headphones after 20-60 minutes of listening. The best Assistive Listening Device speakers use digital algorithms to remove speech from the TV soundtrack, and then manipulate the voices to make them more clear. But recently a different type of TV assisted listening device has evolved - the ALD speaker. Traditionally these devices consist of a device connected to the TV that send signals wirelessly to a set of heaphones. A common variety of assisted listening device is designed to be connected to a TV to allow the viewer to better understand dialogue.
