 Innovations in Hearing Aid Technology

Bluetooth

Bluetooth technology allows hearing aid users to stream content directly from their device to their hearing aids. The listener has access to both environmental sounds and appropriately       amplified streamed audio.

Pros: connects to personal and school devices (i.e. phones, tablets) without intermediary devices.

Cons: battery consumption, dependent on reliable Bluetooth connection.

Rechargeable

Rather than using disposable batteries, rechargeable hearing aids are docked in a charging unit overnight. Built-in batteries cannot be replaced by the user; shelf-life is estimated to be               approximately 5 years.

Pros: environmentally friendly, protects young children and pets from battery toxicity.

Cons: dependency on charging unit, users may forget or be unable to charge hearing aids every night.

Accessibility

Pediatric hearing aids are equipped to connect to special microphones allowing the student to stream the speaker’s voice directly to their hearing aids (i.e. FM/DM systems and remote             microphones).

Pros: increased audibility from a distance or in noisy environments. Connect to non-Bluetooth    devices.

Cons: teachers need to remember to turn the microphone off/mute when appropriate.

Smart Phones

Manufacturers have released smartphone apps compatible with their products. App may include battery life estimates, volume/program adjustments, wear-time monitoring, and Find My Hearing Aid features.

Pros: allows more user control and information.

Cons: newly developed, some “bugs” remain (i.e. variable accuracy, unreliable pairing with      hearing aids).
