    This study details designing and building an induction loop system for classrooms. The induction loop listening system significantly improved speech perception for hearing-impaired individuals, with or without hearing aids.

    Area of Science:

    • Audiology
    • Acoustical Engineering
    • Assistive Technology

    Background:

    • Hearing impairment presents significant challenges in educational settings.
    • Traditional audio systems like loudspeakers can be ineffective for many individuals with hearing loss.

    Purpose of the Study:

    • To discuss the design principles of an induction loop listening system.
    • To present practical procedures for constructing an induction loop.
    • To evaluate the effectiveness of an installed induction loop in a classroom environment.

    Main Methods:

    • Designed and constructed an induction loop system for a medium-sized classroom.
    • Conducted comparative listening tests between the induction loop and loudspeakers.
    • Recruited two groups of hearing-impaired listeners: one with hearing aids and one without.

    Main Results:

    • Speech perception was enhanced for both groups of hearing-impaired listeners when using the induction loop system compared to loudspeakers.
    • The induction loop provided a superior listening experience for individuals with hearing impairments in a classroom setting.

    Conclusions:

    • Induction loop systems offer a viable and effective solution for improving auditory accessibility in classrooms.
    • The design and implementation of induction loops can significantly benefit individuals with hearing loss, regardless of hearing aid usage.
