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.
