Abstract: One embodiment provides a computer-implemented method that includes acquiring, via at least one microphone, sound pressure data from a loudspeaker in a room. The sound pressure data is input into an artificial intelligence (AI) model. The AI model automatically estimates, without user interaction, at least one of energy average (EA) in a listening area or total sound power (TSP) produced by the loudspeaker. The AI model is trained prior to automatically estimating the at least one of the EA in the listening area or the TSP produced by the loudspeaker.

Abstract: An example method of operation may include initiating an automated tuning procedure, detecting via one or more microphones a sound measurement associated with an output of one or more speakers at two or more locations, determining a number of speech transmission index (STI) values equal to a number of microphones, and averaging the speech transmission index values to identify a single speech transmission index value.

Abstract: A sound system for implementing a sound stage through a connection between a sound source and vehicle sound systems and a method for implementing a sound stage thereof may include a source device that provides sound data and a first vehicle and at least one second vehicle connected with the source device through short range wireless communication. The first vehicle enters a sound stage mode, searches for the at least one second vehicle based on a predetermined sound stage type, specifies a speaker role of each of the at least one second vehicle, transmits the specified speaker role and source device connection information to the at least one second vehicle, and connects the first vehicle and the at least one second vehicle with the source device based on the specified speaker role and the source device connection information to implement a sound stage.

Abstract: Techniques for determining the directional frequency response of an arrangement of transducer elements are disclosed. In an example, a method includes providing a simulation of locations of the transducer elements, in the spatial domain; providing a beamforming direction and a frequency range; converting the simulation of locations from the spatial domain into corresponding frequency response values in a spatial frequency domain, such that, for each frequency of a plurality of frequencies in the frequency range, a spatial frequency contour is defined, each of the spatial frequency contours intersecting at the origin; determining the frequency response by applying a transformation to the frequency response values for the provided beamforming direction and frequency range and translating the spatial frequency domain into a modified frequency domain; and outputting the frequency response.

Abstract: A method and multimedia device for calibrating audio delays of an audio system with wireless loudspeakers are disclosed. The method allows to emulate surround or 3D sound systems with spatially distributed wireless loudspeakers. A first probe signal for audio playback, having a first audio pattern, is transmitted by a loudspeaker. A signal quality is determined by listening to an acoustic response of the loudspeaker to the first probe signal. A second audio pattern is determined by modifying the first audio pattern based on the signal quality. A second probe signal for audio playback having the second audio pattern is transmitted by the loudspeaker. An audio delay compensation is then determined for the loudspeaker based on a measure of an audio delay between the transmitted second probe signal and an acoustic response of the loudspeaker in response to the second probe signal.

Abstract: One embodiment provides a method comprising optimizing one or more stimuli parameters by applying machine learning to training data. The method further comprises determining, based on the one or more optimized stimuli parameters, stimuli for simultaneously exciting a plurality of speakers within a spatial area. The stimuli has a shortest possible duration that is accurate for simultaneous deconvolution of a plurality of impulse responses of the plurality of speakers. The method further comprises simultaneously exciting the plurality of speakers by providing the stimuli to the plurality of speakers at the same time for reproduction. The method further comprises simultaneously deconvolving the plurality of impulse responses based on the stimuli and one or more measurements of sound recorded during the reproduction and arriving at one or more microphones within the spatial area.

Abstract: An auditory guidance system is installed along a predefined pathway between an initial location and a target location. The auditory guidance system comprises a plurality of nodes arranged at intervals along the predefined pathway. A first node of the plurality of nodes is a closest node to the initial location and a last node of the plurality of nodes is a closest node to the target location. Each node of the plurality of nodes comprises two directional sound generators. Each of the two directional sound generators are configured to emit sound in a predetermined direction. The two directional sound generators within each node are pointing in opposite directions along the predefined pathway.
