BV-8 data sheet

Product catalog summary

Overview: The Bravissimo BV-8 is a 100% digital mini behind-the-ear (BTE) hearing aid designed by Widex. It offers advanced features to enhance speech intelligibility and listening comfort for users with minimal to moderately severe hearing losses.

Key Features:

Digital Signal Processing (DSP): Utilizes a 3-channel DSP for efficient sound processing.
Wide Dynamic Range Compression: Maximizes speech clarity and comfort.
Automatic Feedback Management: Reduces acoustic feedback.
Variable Crossover Frequencies: Automatically calculated for optimal performance.
Programming Compatibility: Easily programmed with Compass/NOAH or SP3 systems.
Fitting Rationale: Based on four audiometric hearing thresholds, including pediatric rationale and air-bone gap (ABG) compensation.
Fine Tuning System: Includes automatic maximum power output (MPO), insertion gain adjustment, and feedback verification across three channels.
Microphone Noise Reduction: Eliminates internal noise for clearer sound.
Sound Stabilizer: Balances fast and slow regulation times for natural sound quality.
Input Dynamic Range: Improved for better sound quality.
Program Selector: Push-button with beep-tone indicator for flexible program selection.
Telecoil Features: Equalized frequency response, adjustable gain, and anti-hum filter.
Volume Control: Digital control with a +/- 6 dB range and beep-tone adjustment indicator.
Direct Audio Input: Available for enhanced connectivity.
Battery Features: Tamper-resistant drawer, long life of approximately 450 hours with a zinc-air type 13 battery, and low battery beep-tone indicator.
Design Options: Available in three standard colors and seven modern, transparent colors.

Technical Specifications:

Output: Maximum output and gain measured using IEC and ANSI standards, with specific values for 1600 Hz, peak, and average outputs.
Frequency Range: 100 Hz to 7400 Hz, varying slightly with different standards.
Harmonic Distortion: Low distortion levels at 500 Hz, 800 Hz, and 1600 Hz.
Equivalent Input Noise: 23 dB SPL.
Battery Drain: 0.6 mA in standby and active modes.
Battery Life: Approximately 450 hours with a type 13 zinc-air battery.
IRIL (GSM/DECT): Measured at 5/14 dB SPL according to IEC 60118-13.

Recommendations: The Bravissimo BV-8 is recommended for individuals with minimal to moderately severe hearing losses and is suitable for various hearing loss configurations, including conductive, sloping, flat, and reverse slope losses.
