  • Publication number: 20190373392
    Abstract: Techniques of rendering sound for a listener involve determining, at a first position, a set of directions from which some specified fraction of the sound field energy originates and reconstruct the sound field at a second position based on the set of directions. Along these lines, a sound rendering computer may receive sound data representing sound emanating from positions on a sphere centered on a microphone. Nevertheless, only a small fraction of these points on the sphere contribute much of the sound field energy directed at the listener. The sound rendering computer determines such directions using a directional decomposition in which those directions having the highest fraction of the sound energy are identified. When the listener moves away from the microphone's position, the sound rendering computer, after identifying such directions, applies an amplitude and phase factor to the sound fields corresponding to those directions.

  • Patent number: 10492018
    Abstract: Techniques of performing binaural rendering involve combining left and right HRTFs from speakers symmetrically placed with respect to a forward axis of a listener's head. Because of the symmetry of the listening geometry, a decoded loudspeaker signal resulting from each speaker may be decomposed into symmetric and antisymmetric components according to whether a spherical harmonic associated with a respective ambisonic channel is symmetric or antisymmetric about the forward axis. The result involves rendering the left and right headphone speakers using the same sum and difference HRTFs rather than a different pair of HRFTs for each headphone speaker.

  • Patent number: 10473494
    Abstract: Flow sensors are provided that can provide both leak detection and flow monitoring. The flow monitoring enables a determination whether there are blockages or leaks in a fluid system during normal operation of the system. The leak detection enables detection of leaks when the system is shut off. The flow sensors can use a frusto-conical flow guide to provide a more compact flow sensor. The flow sensor components can be designed to retrofit existing filter assemblies.

  • Publication number: 20190341060
    Abstract: A computing device includes a processor and a memory. The processor is configured to generate spectrograms, for example, using short-time Fourier transform, for a plurality of channels of reference and test ambisonic signals. In some implementations, the test ambisonic signal may be generated by decoding an encoded version of the reference ambisonic signal. The processor is further configured to compare, for each of the plurality of channels of a reference ambisonic signal, at least a patch associated with a channel of the reference ambisonic signal with at least a corresponding patch of a corresponding channel of the test ambisonic signal and determine a localization accuracy of the test ambisonic signal based on the comparison. In some implementations, the comparing may be based on phaseograms of the reference and test ambisonic signals.

  • Publication number: 20190226987
    Abstract: The present invention makes use of a modular Folded Tubular Photometer to measure the concentrations of gas-phase species and/or particles, including especially air pollutants such as ozone (O3), nitrogen dioxide (NO2), sulfur dioxide (SO2) and black carbon particulate matter, by means of absorbance of ultraviolet (UV), visible or infrared (IR) light. The optical bench makes use of modular components (tubes and mirror assemblies) that allow construction of path lengths of up to 2 meters or more while maintaining low detection cell volumes. The long path lengths, low cell volumes, and the innovation of pressure equalization during the absorbance measurements enable sensitive detection of ambient air pollutants down to low part-per-billion levels or less for gas species, and extinctions down to 1 Mm?1 or less for particulate matter, corresponding to ˜0.13 ?g/m3 or less for black carbon particulates.

  • Publication number: 20190069110
    Abstract: A method of encoding sound objects includes receiving a set of monophonic sound inputs. Each of the set of monophonic sound inputs includes position and orientation information of a sound object relative to a source position. The set of monophonic sound inputs are encoded into a higher order ambisonic (HOA) sound field in a spherical harmonics domain based on a spherical harmonics dataset including a subset of all spherical harmonic coefficients for a given subset of azimuth and elevation angles. Some embodiments include decoding the HOA sound field to generate a set of loudspeaker signals.

  • Patent number: 10158963
    Abstract: Techniques of performing involve providing interactive audio in addition to ambisonic audio in stereo tracks selected according to the occurrence of events in a media delivery system. For example, a user of a VR system observes a virtual environment that contains many virtual objects. The user may experience binaurally rendered audio played over N ambisonic channels from any number of virtual loudspeakers. In addition, the user may also activate another audio source by positioning his/her head at a certain angle, e.g., to look at a particular virtual object. As a specific example, when the user looks at a picture of a person, an audio track may play over a pair of stereo channels N+1 and N+2. Because they are stereo channels, there is no need to perform convolutions with HRTFs. In this way, audio may be provided for all virtual objects in the virtual environment with a small computational overhead.

  • Publication number: 20180212690
    Abstract: Provided are methods and systems for improving the intelligibility of speech in a noisy environment. A communication model is developed that includes noise inherent in the message production and message interpretation processes, and considers that these noises have fixed signal-to-noise ratios. The communication model forms the basis of an algorithm designed to optimize the intelligibility of speech in a noisy environment. The intelligibility optimization algorithm only does something (e.g., manipulates the audio signal) when needed, and thus if no noise is present the algorithm does not alter or otherwise interfere with the audio signals, thereby preventing any speech distortion. The algorithm is also very fast and efficient in comparison to most existing approaches for speech intelligibility enhancement, and therefore the algorithm lends itself to easy implementation in an appropriate device (e.g., cellular phone or smartphone).
