Audio Lens (prioritizing sounds in the home)

Audio Lens is an in home microphone installation designed that sorts incoming sounds and delivers them to the user based on priority. The user places bluetooth microphones in different locations around the house (TV, front door, kitchen) and sets their inputs from highest priority to lowest. Audio incoming to a higher priority location/microphone attenuates all sounds of lower priority, thus, the user hears only one sound source at a time. The installation gives the user the power to dictate what sounds are important to them and what they want to hear.

Have a listen to this audio clip and follow the corresponding timeline below.

The user, by means of a physical interface, has selected these sound sources to listen to in this priority (1 is the highest, 4 is the lowest)

1) Front Door
2) Telephone
3) Daughter
4) Television

From 0:00 - 0:17, the user listens to a television commercial:
1) front door
2) telephone
3) Daughter
4) Television

Then, at 00:17, the daughter, wearing a microphone, begins to speak about how she loathes the wizard of oz. Her voice is higher priority than the television, so, the television is attenuated and the daughter is amplified:
1) front door
2) telephone
3) Daughter
4) Television

Then, at 0:22, the phone rings, attenuating the daughters speech because the phone is an even higher priority:
1) front door
2) telephone
3) Daughter
4) Television

From 0:25 to 0:27, the phone halts ringing for a bit and the daughters voice is heard again:
1) front door
2) telephone
3) Daughter
4) Television

At 0:38, the knocking of the door attenuates all sounds in the home because it is the highest priority.
1) front door
2) telephone
3) Daughter
4) Television

Notice the smooth transition between sounds of different priorities, and when a higher priority sound is active, it only attenuates the lower priority sounds and doesn't completely mute them.

This experiment was originally performed by audio engineer Bernard Fox whom I helped to begin to improve the scheme by removing the ancient microphone/analog gear and implement a cost effective bluetooth digital interface.
