Description of Active Noise Barrier (ABB)

Abstract

Active Noise Barrier (ANB) is a technology that cancels the propagation of sound waves by using destructive sound wave interference. This technology works by creating a destructive barrier, thus preventing the propagation of sound by generating sound waves with an opposite phase to the unwanted sounds within a barrier space, resulting in sound reduction and / or cancellation through superposition. This technology can be installed in front of a window to cancel the propagation of sound waves, preventing noise from entering and / or leaving a user-defined space.

[0002] Active Noise Barrier (ANB) is a technology that cancels the propagation of sound waves by using destructive sound wave interference. This technology works by creating a destructive barrier, thus preventing the propagation of sound by generating sound waves with an opposite phase to that of the unwanted sounds in a space designated as the barrier, resulting in a reduction and / or cancellation of the sounds through superposition. This technology can be installed in front of a window to cancel the propagation of sound waves so that noise does not enter and / or leave a space defined by the user. This system can also be installed above a door, in ceilings, in front of an entrance threshold, or in any space requiring sound protection in the form of a barrier.

1. This system consists of a coordinated set of electronic and software components, including microphones, a digital signal processor (DSP), loudspeakers, and one or more amplifiers. The following is a detailed description of the BAB system, including its operation and technical components. Microphones Type: Omnidirectional condenser microphones. Function: To capture ambient sounds (noise) approaching the environment where the BAB system is installed. Placement: The microphones are strategically placed to capture sounds from various directions. Digital Signal Processor (DSP) Type: High-performance DSP with real-time audio processing capabilities. Function: Analysis: The DSP receives signals from the microphones and analyzes the characteristics of the sound waves.Inverted Wave Generation: Based on analysis, the DSP generates inverted sound waves (180 degrees out of phase*Appendix 1) to cancel the propagation of unwanted sounds through destructive interference. Filtering and Adjustment: Uses adaptive filtering algorithms to constantly adjust the inverted waves according to variations in ambient noise. Amplifier Type: Integrated Class D amplifier. Function: Amplification: Amplifies the audio signals generated by the DSP before sending them to the speakers. Power Management: Ensures sufficient power for the speakers while maintaining energy efficiency. Speakers Type: Full-range speakers. Function: Inverted Wave Emission: The speakers emit the inverted waves generated by the DSP to cancel the propagation of ambient sound waves within a defined area, acting as a barrier.Coverage Optimization: Position the speakers to maximize noise cancellation effectiveness in the target environment.

2. Method: Operation of the BAB System 1 / Ambient Sound Detection: The microphones capture ambient sounds and transmit them as electrical signals to the DSP. 2 / Sound Analysis and Processing: The DSP analyzes these signals to identify the characteristics and origin of the ambient noise. 3 / Generation of Inverse Waves: The DSP generates cancellation signals (inverse waves) to neutralize the propagation of unwanted sounds. 4 / Signal Amplification: The cancellation signals are amplified by the integrated amplifier in order to optimize the cancellation of sound propagation. 5 / Emission of Inverse Waves: The loudspeakers diffuse the inverse waves in a defined space whose characteristic can be described as a barrier, thus canceling the propagation of sound waves from ambient noise.
