2. The technology at the foundation of Signia’s bilateral beamforming is: Full audio data transfer with nearfield magnetic induction (NFMI) Bluetooth classic 2.4 GHz Bluetooth low energy
3. Motion sensors on-board Signia hearing aids use which technology? Accelerometer Gyroscope Bluetooth low energy NFMI
4. Bilateral beamforming is activated at which approximate intensity level? 55 dB SPL 80 dB SPL 70 dB SPL 45 dB SPL
5. Which of the following is an accurate statement regarding Augmented Focus? It shapes sounds in the listener’s environment using two separate processors that apply different amounts of gain, compression and noise reduction in each processor It processes sound in a serial arrangement It uses the dominant signal to process all sounds in the listener’s environment the same way Like a directional microphone, it amplifies the signal in front of the wearer and reduces all sounds to the side and back of the wearer
