There are two ways to customize BeHear:
Using the built-in Hearing Assessment in the smartphone app, which applies the results automatically to the four presets (Indoor, Outdoor, Crowd, Live Music -- and Telecoil/Telecoil Exclusive for BeHear ACCESS) to match your preferences and capabilities.
In real-time, using the controls in the Home section of the smartphone app to select a preset relevant to your current hearing situation. Then, click the "equalizer" button at the bottom of this screen to access the "Sound Tuning" section to fine-tune gain across frequencies, and below the grid determine the amount of noise reduction you prefer.
