摘要： [Object] To reduce the influence of noise in a more preferred aspect even in an environment in which a user hears an acoustic sound output to an open space.[Solution] A signal processing device includes: a generation unit configured to generate a first noise reduction signal for driving a first acoustic device which outputs a first acoustic sound for reducing noise; and an acquisition unit configured to acquire a sound collection result of an acoustic sound collected by a predetermined sound collection unit, the acoustic sound including the first acoustic sound propagating from the first acoustic device via a first propagation path and a second acoustic sound propagating from a second acoustic device different from the first acoustic device via a second propagation path. The generation unit generates the first noise reduction signal on a basis of the sound collection result and a cancellation signal based on a second noise reduction signal for driving the second acoustic device.

摘要： The present invention relates to a method and to an apparatus, both arranged for controlling acoustic signals to be recorded or reproduced by an electro-acoustical sound system. For this purpose: an initial digital filter is determined by solving an inverse problem, wherein the initial digital filter is configured to control acoustic signals to be recorded and/or reproduced by the electro-acoustical sound system; a frequency-dependent articulation parameter is determined by executing a time spectral psychoacoustic automatic audio quality test on the initial digital filter; a frequency-dependent regularization parameter, used for determining the initial digital filter, is tuned by use of the frequency-dependent articulation parameter; and, by use of the tuned frequency-dependent regularization parameter, a digital filter configured to control acoustic signals to be recorded or reproduced by the electro-acoustical sound system is determined.

摘要： The present disclosure provides methods and systems for homogenizing a low frequency listening experience for users in a plurality of locations, such as a plurality of seat positions in a vehicle. An example audio system includes a plurality of woofers configured to output low frequency sound into a listening environment to yield a homogeneous low frequency sound field. Homogeneity of the low frequency sound field in this case is for example spectrally uniform throughout an extended listening space.

摘要： A dynamic arrangement for loudspeaker grilles is disclosed. A first perforated grille is operable to move with respect to a second perforated grille. The relative movement is controlled to cause the two respective sets of perforations to fall in or out of alignment as required, leading to advantageous effects such as different levels of acoustic transparency.

摘要： A method of providing navigation on an electronic device when the display screen is locked. The method receives a verbal request to start navigation while the display is locked. The method identifies a route from a current location to a destination based on the received verbal request. While the display screen is locked, the method provides navigational directions on the electronic device from the current location of the electronic device to the destination. Some embodiments provide a method for processing a verbal search request. The method receives a navigation-related verbal search request and prepares a sequential list of the search results based on the received request. The method then provides audible information to present a search result from the sequential list. The method presents the search results in a batch form until the user selects a search result, the user terminates the search, or the search items are exhausted.

摘要： Method and apparatus are disclosed for monitoring of vehicle window vibrations for voice-command recognition. An example vehicle includes a window, an outer layer, a vibration sensor coupled to the window to detect audio vibrations, an audio actuator coupled to the outer layer to vibrate the outer layer, and a controller. The controller is to detect a voice command from a user via the vibration sensor, identify an audio response based upon the voice command, and emit the audio response to the user via the audio actuator.
