How many microphones does SMARTO have, and what is their purpose?
BeHear SMARTO has three microphones (two in the hand-held device, and one in the supplied headset — over-the-ear, or in-ear). They all are used to pick up the conversation.
The two embedded microphones in the hand-held device pick up sound and determine directionality, as well as serve to reduce environmental noise (including contact with the hand-held device by hands or clothes).
The microphone in the headset is used during mobile phone calls, as it is closest to the mouth. Therefore, during these calls there is no need to hold SMARTO in your hand. It can hang around your neck on the lanyard, be clipped to a pocket or purse, or placed on a nearby surface.
How can I use BeHear to hear better in noisy places?
Our BeHear headsets have technology for enhancing nearby speech while dampening down distracting background noise. When in Personal Hearing mode (i.e., no audio is being streamed, and no phone call is in progress) these options are reached by tapping the “equalizer” button at the bottom of the Home screen.
For BeHear ACCESS you can choose the “sound focus” area: Narrow (directly in front of you); Wide (180 degrees in front of you); or Omni (360 degrees).
For all BeHear headsets (PROXY needs to be in Earphone mode), you can customize what you hear in real time with these two features:
- Background Noise scale: If the background noise is bothering you, the Noise Reduction levels will help screen those out.
- Sound Tuning (or Best Sound Point – BSP) grid: Tap the dot in the Sound Tuning section to display this feature.
Using the Sound Tuning Grid
There are four microphones in the headset (two in the ear buds and two in the control boxes, which lie near your collarbone). These microphones pick up ambient, nearby sounds, like your conversation.
Use the grid to focus on your conversation partner by choosing a square that sounds best to your ears (depending on the pitch of the partner’s voice). Each square in the grid defines a specific sound level which is a unique combination of frequency (left to right is low to high) and amplitude (bottom to top is low to high). The edges of the grid represent the extreme combinations. For more information about this grid, read this post.
