Ezairo® Sound Designer Software Application


Modeler
Measure the frequency response of your hearing aid's microphones and receivers to allow accurate modeling of real-world performance.

Map Editor
Customize firmware bundles by filtering exposed algorithm parameters, setting default values, and restricting ranges.

Library Manager
Combine your transducer models with mappings created with the Map Editor to define one or more products packaged in a single Product library.

Control Panel
Aided by the modeled response of the system, fine-tune all module and algorithm parameters within each hearing aid memory/profile to meet specific acoustic use cases.

CalConfig
Calibrate the device's transducers and configure the hearing aid with your specified set of parameters, voice alerts, and scratch memory.
