BV-19 data sheet

Product catalog summary

Overview: The Bravissimo BV-19 is a 100% digital behind-the-ear (BTE) hearing aid designed for moderate to severe hearing losses. It features advanced digital signal processing (DSP) with a 3-channel system, directional microphones, and wide dynamic range compression to enhance speech intelligibility and listening comfort.

Key Features:

Directional microphone for optimal signal-to-noise ratio.
Automatic feedback management to reduce acoustic feedback.
Variable crossover frequencies calculated automatically.
Flexible programming with Compass/NOAH or SP3.
Paediatric rationale and air-bone gap (ABG) compensation.
Microphone noise reduction and sound stabilizer for natural sound quality.
Push-button program selector with beep-tone indicator.
Equalised telecoil frequency response and adjustable telecoil gain.
Digital volume control with a +/- 6 dB range.
Direct audio input and battery drawer lock for children.
Available in multiple colors with a long battery life of approximately 435 hours.
