induction loop system
C1Technical/Formal
Definition
Meaning
A system that uses electromagnetic induction to transmit audio signals directly to hearing aids or compatible receivers, primarily for accessibility in public spaces.
May refer to any audio transmission system utilizing inductive coupling, sometimes applied in telecommunications, security, or specialized audio environments.
Linguistics
Semantic Notes
Specifically associated with assistive listening for hearing impairments; emphasizes the inductive loop component rather than other transmission methods.
Dialectal Variation
British vs American Usage
Differences
In British English, 'induction loop system' is the standard term; in American English, 'hearing loop' or 'audio induction loop' is more commonly used.
Connotations
Both refer to the same technology with no significant connotative differences, though the British term may sound more formal.
Frequency
The term is more frequently encountered in the UK due to stringent accessibility regulations and standards.

Common Pitfalls
Translation Traps (for Russian speakers)
- Прямой перевод 'индукционная петлевая система' может звучать неестественно; более стандартно 'система индукционной петли' в технических контекстах.
- Избегайте путаницы с 'индукцией' в смысле логического вывода; здесь речь об электромагнитной индукции.
Common Mistakes
- Mispronouncing 'induction' as /ɪnˈdʊkʃən/ instead of /ɪnˈdʌkʃən/.
- Using 'induction loop system' as a blanket term for all assistive listening systems, when it specifically denotes inductive technology.

FAQ
Frequently Asked Questions
It is an assistive listening technology that uses electromagnetic induction to send audio directly to hearing aids or receivers, enhancing sound clarity for individuals with hearing impairments.
They are commonly found in public venues like theatres, churches, museums, airports, and banks to comply with accessibility standards.
A loop of wire carries an audio-frequency current, creating a magnetic field that is picked up by the telecoil in a hearing aid, converting it back into sound.
No, only hearing aids equipped with a telecoil (T-coil) can use induction loop systems directly; otherwise, a separate receiver is required.
