Abstract: Embodiments include a microphone assembly comprising an array microphone and a housing configured to support the array microphone and sized and shaped to be mountable in a drop ceiling in place of at least one of a plurality of ceiling tiles included in the drop ceiling. A front face of the housing includes a sound-permeable screen having a size and shape that is substantially similar to the at least one of the plurality of ceiling tiles. Embodiments also include an array microphone system comprising a plurality of microphones arranged, on a substrate, in a number of concentric, nested rings of varying sizes around a central point of the substrate. Each ring comprises a subset of the plurality of microphones positioned at predetermined intervals along a circumference of the ring.

Abstract: Methods and systems for identifying abnormal sounds in a particular environment. A normal audio stream obtained in the absence of abnormal sounds may be used as a baseline for subsequently processing an incoming audio stream with a processor to determine whether the incoming audio stream from the microphone in the particular environment includes an abnormal audio event for the particular environment. When it is determined that the incoming audio stream includes an abnormal audio event for the particular environment an electronic database may be accessed to determine a location of the abnormal audio event in the particular environment. A video camera with a field of view that includes the location of the abnormal audio event in the particular environment may be identified and the video stream from the identified video camera retrieved and displayed.

Abstract: An apparatus is configured to rest on a wearer's neck or shoulders, and has a first microphone positioned at a first position located on the right side of the wearer, when the apparatus is worn, and a second microphone positioned at a second position located on the left side of the wearer. A processor receives audio signals output by the first and second microphones, and compares the audio signals from the first microphone to the audio signals from the second microphone. Based on the comparison, the processor determines whether the wearer's head is rotated to the right, left, or center, during an instance of the user speaking. Based on the determination, the processor selects a first one of at least two audio signal destinations, and provides the audio signal from at least one of the microphones to the first selected audio signal destination.

Abstract: A lighting system includes a first lighting fixture that includes a first microphone and a first transmitter. The first transmitter is configured to transmit a first digital audio stream generated based on a sound. The lighting system further includes a second lighting fixture that includes a second microphone and a second transmitter. The second transmitter is configured to transmit a second digital audio stream generated based on the sound, where the sound is received by the first microphone and by the second microphone. The lighting system also includes a central processor that can process the first digital audio stream and the second digital audio stream to identify the sound.

Abstract: Example embodiments disclosed herein relate to user experience oriented audio signal processing. There is provided a method for user experience oriented audio signal processing. The method includes obtaining a first audio signal from an audio sensor of an electronic device; computing, based on the first audio signal, a compensation factor for an acoustic path from the electronic device to a listener and applying the compensation factor to a second audio signal outputted from the electronic device. Corresponding system and computer program products are disclosed.

Abstract: According to the invention, a system for converting sound to electrical signals is disclosed. The system may include a gaze tracking device and a microphone. The gaze tracking device may determine a gaze direction of a user. The microphone may be more sensitive in a selected direction than at least one other direction and alter the selected direction based at least in part on the gaze direction determined by the gaze tracking device.

Abstract: Methods and devices are disclosed for attracting animals. A game call speaker system having a body portion, first speaker unit configured to rotate about a first axis, a second speaker unit configured to rotate about a second axis and a memory comprising one or more stored game calls is provided. Rotation of the first speaker unit may be independent of rotation of the second speaker unit. The first axis may be substantially parallel to the second axis. In some embodiments, the game call speaker system is configured to emit the stored game calls over a relatively wide angle (e.g., 360 degrees) relative to the body portion.
