Abstract
According to an exemplary embodiment of the present invention, an acoustic manipulator element is provided. The acoustic manipulator element is arrangable relatively to an acoustic source in a manner that the acoustic manipulator element splits frequency selectively sound waves originating from the acoustic source in a reflected and a through component, wherein at least a portion of the acoustic waves of the through component is attenuated by at most 15 dB for acoustic frequencies having a wavelength between 200 Hz and 16000 Hz compared to the sound waves of the acoustic source.
Claims10
Acoustic manipulator element being arrangable relatively to the acoustic source in a manner that the acoustic manipulator element selectively splits sound waves originating from the acoustic source in a reflected and a through component,
- wherein the acoustic manipulator element comprises a first element as base plate and a second element attached to the first element as diffuser,
- wherein the first element comprises a triangle-shaped cutout,
- wherein the second element is pyramid-shaped with an open bottom and one open side surface,
- wherein the second element is attached to the first element such that the open bottom of the second element corresponds to the cutout of the first element, and
- wherein at least a portion of the acoustic waves of the through component is attenuated by at most 15 dB for acoustic frequencies between 200 Hz and 15000 Hz compared to the sound waves of the acoustic source.
Method for splitting sound waves by an acoustic manipulator element into a reflected and a through component, the method comprising:
- encountering, with the acoustic manipulator element, sound waves produced by an acoustic source;
- splitting frequency selectively sound waves originating from an acoustic source in a reflected and a through component by the acoustic manipulator element having a first element as base plate and a second element attached to the first element as diffuser, wherein the first element comprises a triangle-shaped cutout, wherein the second element is pyramid-shaped with an open bottom and one open side surface, wherein the second element is attached to the first element such that the open bottom of the second element corresponds to the cutout of the first element, and wherein at least a portion of the acoustic waves of the through component is attenuated by at most 15 dB for acoustic frequencies between 200 Hz and 16000 Hz compared to the sound waves of the acoustic source.
A non-transitory computer-readable medium, in which a computer program of splitting sound waves in a reflected and a through component is stored, which computer program, when being executed by a processor, is adapted to carry out or control a method for splitting sound waves in a reflected and a through component, the method comprising splitting frequency selectively sound waves originating from an acoustic source in a reflected and a through component to thereby simulate the acoustic effects of an acoustic manipulator element, which comprises a first element as base plate and a second element attached to the first element as diffuser, by the use of software.
A method for splitting sound waves originating from an acoustic sound source, the method comprising:
- receiving a digital signal representative of the acoustic sound source;
- processing the digital signal with a processor;
- dividing the digital signal into a reflected component and a through component to simulate acoustic effects of an acoustic manipulator element, which comprises a first element as base plate and a second element attached to the first element as a diffuser, by the use of an informational model that characterizes sound waves that would be attenuated and transmitted through the acoustic manipulator element and of portions of sound waves that would be reflected by the acoustic manipulator element;
- converting the reflected component and the through component to analog signals;
- and
- applying the analog signals to loudspeakers for generating sound waves corresponding to the reflected component and the through component.
