The present disclosure provides apparatuses and methods of processing a sound from an engine or a vehicle. The apparatus for processing a sound from the engine includes: an engine to generate an engine sound; a sensing device to sense vibration of the engine; a controller to generate a reinforcing signal to reinforce a region of the engine sound based on the vibration and an output unit to output a reinforcing sound corresponding to the reinforcing signal.

An apparatus includes: a driving route calculator configured to obtain vehicle information about a vehicle and calculate a driving path of the vehicle; an object detector configured to detect an object near the vehicle or the driving path of the vehicle using one or more sensors mounted on the vehicle, and obtain object information on the object; and an acoustic signal processor configured to control a frequency and a volume of an acoustic signal based on the vehicle information and the object information, and transmit the acoustic signal to a speaker mounted on the vehicle.

Described herein is a method of processing audio content for rendering in a three-dimensional audio scene, wherein the audio content comprises a sound source at a source position, the method comprising: obtaining a voxelized representation of the three-dimensional audio scene, wherein the voxelized representation indicates volume elements in which sound can propagate and volume elements by which sound is occluded; generating a two-dimensional projection map for the audio scene based on the voxelized representation by applying a projection operation to the voxelized representation that projects onto a horizontal plane; and determining parameters indicating a virtual source position of a virtual sound source based on the source position, a listener position, and the projection map, to simulate, by rendering a virtual source signal from the virtual source position, an impact of acoustic diffraction by the three-dimensional audio scene on a source signal of the sound source at the source position. Described are moreover a corresponding apparatus as well as corresponding computer program products.

A vehicle for blocking a virtual engine sound that is introduced into the vehicle includes: a speed sensor configured to detect a travelling speed of the vehicle; a virtual engine sound system (VESS) including a first speaker and a second speaker; and a controller configured to control the VESS based on the travelling speed, wherein the controller is configured to: upon the vehicle being in a stopped state, control the VESS such that the first speaker outputs a virtual engine sound and the second speaker outputs a sound having an inverse phase of the virtual engine sound.

A wave generator has a wave emitter including an elongated dispersive waveguide and a source operatively connected to a first end of the waveguide. The source covers at least partially a surface area thereof. A signal generator is in operative connection with the transducer to create electrical signals. A computer is in operative connection with the signal generator to cause it to generate the electrical signals. A mechanical input wave is created by the source at the first end of the waveguide. The mechanical input wave is constructed independently of data related to a mechanical wave received from a source in the medium and taking into account the different predetermined propagation velocities of at least two component waves of the mechanical input wave so that they combine with each other at a second end of the waveguide to form the desired mechanical output wave in the medium.

Current bidirectional broadcasting systems do not consider the reduced level of performance by performers when distributing a no-audience live performance. Provided is a bidirectional broadcasting method enabling an audience to enjoy a live performance distributed through a monitor, and characterized by comprising collecting reaction sound in real time from each audience member in response to a live distribution, outputting the real-time reaction sound from each audience member in response to the live distribution as an analog acoustic signal to speakers installed in a live event venue from which the live event is being distributed over a communication channel, and communicating, to a live performer in real time, the reactions of the audience members to the live distribution.

An apparatus and a method for controlling a vehicle sound are provided. The apparatus a detection device that detects driving information and drive mode setting information and a processing device electrically connected with the detection device. The processing device determines an emotional state of a driver based on at least one of the driving information or the drive mode setting information, determines a sound concept depending on the emotional state of the driver, and controls a vehicle sound depending on the sound concept.

Disclosed is a sound design method for overcoming sense of difference when there is no virtual sound while an auto cruise control is activated. The method includes determining whether an accelerator pedal is actuated; upon determining that the accelerator pedal is not actuated, determining whether an auto cruise control system is operating; upon determining whether the auto cruise control system is operating, classifying a vehicle speed-based order component from a driving sound; and reproducing a speed sensitive virtual sound based on the classified vehicle speed-based order component.
