Hearing Aid Systems

Flashcards detailing key concepts and definitions related to hearing aid systems, construction options, and programming.

Hearing Aid Types

Custom hearing aids, modular hearing aids, and semi-modular, semi-custom hearing aids.

Custom Hearing Aids

Hearing aids tailored for individual users, requiring a custom earmold impression or a laser-scanned image.

Modular Hearing Aids

Hearing aids that can be assembled from standardized parts, often referred to as ready-to-wear.

Linked Bilateral Hearing Aids

Hearing aids that transmit information wirelessly between two aids to improve performance and convenience.

NOAH Standard

A common interface adopted by hearing aid manufacturers for storing patient data and communicating with hearing aids.

FM System

A wireless transmission technology that consists of a transmitter and receiver to enhance hearing in challenging environments.

Digital Modulation (DM)

A method for converting analog sound signals into digital bits for transmission, offering improved sound quality.

Induction Loops

Systems that convert audio signals into electrical currents to create a magnetic field picked up by telecoils in hearing aids.

Speech-operated Switching (SOX) or Voice-operated Switching (VOX)

Automatic microphone switching features in FM systems, prioritizing signals based on detected speech.

Classroom Sound-field Systems

Systems utilizing microphones and loudspeakers to improve signal-to-noise ratio (SNR) for all students in a classroom.
