A ceiling-mounted microphone array enclosure includes a room panel and a top panel. The room panel includes a border of solid material that surrounds a central sound permeable area having sound permeable perforations. The top panel is connected to the room panel through connectors arranged along the border of solid material. The top panel can have sides and be connected to the room panel such that there is a gap to permit improved airflow, or sides of the top panel can connect directly to the bottom panel without a gap. A microphone array and other electronic components can be arranged within the enclosure and then ceiling mounted within a ceiling grid. Multiple differently sized room panels can be manufactured in such a way that they can connect directly to the top panel.

This disclosure describes a personal speakerphone device for teleconferencing a local participant with near side audio data and a far side participant with far side audio data. The device includes a controller that couples to a speaker and a microphone inside an enclosure that couples the speaker and the microphone within a coupling frequency range, and where the enclosure houses the speaker, the microphone, the controller, analog to digital conversion circuitry, digital to analog conversion circuitry, supporting circuitry, and one or more ports for data through which audio data is transferred. Additionally, the device includes a first frequency band decomposer, a second frequency band decomposer, one or more echo cancellers, and a converger. Further, the device includes a primary doubletalk detector and a secondary doubletalk detector.

Disclosed herein are detectors of audio ringing feedback, that is decaying feedback with a gain of less than one, those detectors utilizing a repeated gain measurement that applied to a range of gain values characteristic of ringing-type feedback. Those gain measurements, while in the range, increase a probability measurement of feedback. When the probability of feedback reaches a threshold, a detection of feedback is made and feedback countermeasures, such as the application of a notch filter, may be applied. Optionally, the audio gain around likely frequencies of feedback may be enhanced for a time to increase the resolution of identification of a feedback frequency, which may be identified through an interpolative method. Repeated gain measurements may also identify building-type feedback. A ringing detector may include more than one range of detection, for example for building, strong-ringing and weak-ringing feedback.

Disclosed herein are portable teleconferencing products that implement a doubletalk detector in a low frequency range or in a frequency range commensurate with the frequencies through which sound may be efficiently transferred between a speaker and a microphone through an enclosure. Also disclosed herein are teleconferencing systems that implement a secondary doubletalk detector, a non-presumptive doubletalk detector, a confirmatory doubletalk detector, and/or a false doubletalk detector, whereby echo cancellation coefficients may be better adapted after echo path changing events through the use of accelerated coefficient adaptation or half-duplex operation until adaptation is restored. Further disclosed herein are teleconferencing products that include more than one port for communicating with distant parties or a single party and a local source of audio material, whereby one distant party is prevented from being transmitted to it private audio from another party or another audio signal while permitting a local participant to hear the private audio. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.

Adaptive conferencing pod sidetone compensator connecting to a telephonic device having intermittent sidetone
Disclosed herein are teleconferencing pods that include a microphone and a loudspeaker for open-air conversations, connectible to a separate telephonic device that generates an intermittent sidetone that is active at certain times not in the control or monitoring of the pod. In those pods is a sidetone suppressor that suppresses a distracting open-air echo produced from the intermittent sidetone and a compensator that detects sidetone transitions to avoid generating an echo signal in the pod and to avoid adapting suppression in the absence of an externally-generated sidetone. Sidetone suppression may be by several means, and may include variables controlled by adaption, including delay factors, scalers and coefficients. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.
