Have you ever wondered about the remarkable technology known as an Active Aid listening system (ALS) ? Who use it ? And why ? How is this technology integrated within Audiovisual (AV) systems?
Check these below factors and features for ALS within AV system:
- An active aid listening system, also referred to as an assistive listening system (ALS) , is a cutting-edge solution specifically designed to improve sound transmission and accessibility for individuals with hearing impairments.
- Its utilization spans a diverse range of environments, including classrooms, theaters, conference rooms, and public venues such as Stadiums, Airports and Malls . By employing this technology, we strive to ensure that individuals with hearing loss can fully engage with and comprehend speech and other audio content.
- At its core, an active aid listening system comprises three primary components: a microphone, a transmitter, and a receiver/listener device.
-The microphone captures and amplifies the sound source, be it a speaker's voice or audio output from a sound system.
-The transmitter receives the audio signal from the microphone, converting it into a wireless signal that can be seamlessly transmitted to the listening devices.
-These receiver/listener devices, such as headsets, earphones, or neck loops, receive the wireless signal and directly deliver the audio to the listener's ears. In the case of compatible hearing aids or cochlear implants, the neck loop can interface with these devices to provide an enhanced listening experience.
- This system uses wireless transmission technologies, including radio frequency (RF), infrared (IR), and induction loop systems. Each technology possesses unique advantages and considerations, such as range, interference, and compatibility with hearing aids or cochlear implants. Such considerations ensure optimal performance and compatibility for the end-users based on Design and project requirement.
- It is important to note that active aid listening systems represent just one facet of the wide array of assistive technologies available to individuals with hearing impairments. Other options, including personal hearing amplifiers, FM systems, Bluetooth-enabled devices, and captioning systems, may be utilized either independently or in conjunction with active aid listening systems, depending on the individual's specific needs and preferences.
- The integration of active aid listening systems within AV systems showcases a remarkable synergy. By seamlessly integrating audio technology and accessibility, we can create inclusive environments where individuals with hearing impairments can actively participate and engage with the content being presented.
- ALS systems adhere to international standards to ensure performance, safety, and compatibility. Some notable standards include ADA Standards for Accessible Design, IEC 60118-4, ANSI/ASA S3.22, and EN 60118-4.
