Adaptive Loudspeaker Zone Control for Venue Equalization Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound systems for live concerts require labor-intensive setup and adjustment of loudspeaker arrays to achieve optimal coverage, often resulting in suboptimal performance due to incorrect angles and trim heights, and lack the ability to easily reconfigure zones within a venue for varying acoustic conditions.
Innovation Solution
An adaptive loudspeaker system with individually powered and controlled transducers, each equipped with a digital signal processor channel, and adaptive performance software that allows for real-time adjustment of equalization settings in specific zones within a venue, enabling precise control of sound directionality and equalization across multiple zones without the need to reconfigure the entire system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional loudspeaker arrays are used for live concerts, then the system can provide general sound coverage, but the setup requires labor-intensive manual adjustment and cannot easily reconfigure zones for varying acoustic conditions
Solution Approach 1:
The system divides the venue into multiple independently controllable zones, with each zone having its own equalization settings and transducer groups. This segmentation allows different areas to be optimized separately for varying acoustic conditions without affecting the entire system, enabling flexible reconfiguration without labor-intensive manual adjustments.
Solution Approach 2:
The system implements dynamic zone configuration where boundaries and parameters can be adjusted in real-time based on acoustic conditions and event requirements. The electronic control system allows zones to be reconfigured software-based rather than requiring physical repositioning of loudspeaker arrays, providing adaptability without manual labor.
2Manufacturing precision
If manual adjustment of loudspeaker arrays is performed to achieve optimal coverage, then sound quality can be improved, but the process is labor-intensive and time-consuming
Solution Approach 1:
The system replaces mechanical adjustment of loudspeaker arrays with an electronic control system that uses digital signal processing and software-based zone management. Instead of physically moving and adjusting loudspeaker arrays manually, the system achieves sound coverage optimization through electronic equalization settings and digital signal routing, dramatically reducing setup time while maintaining precision.
Solution Approach 2:
The system optimizes sound coverage by changing acoustic parameters (equalization frequencies, gain levels, phase settings) through software control rather than physical repositioning. This allows rapid adjustment of sound fields by modifying digital parameters, achieving precision optimization without the time-consuming manual labor of physical array adjustment.
3Reliability
If the entire loudspeaker system is reconfigured to adjust equalization settings, then optimal performance can be achieved, but the process affects the entire system rather than specific zones
Solution Approach 1:
The system segments the loudspeaker array into multiple independently controllable zones, each with its own equalization settings. This allows acoustic optimization to be applied locally to specific zones rather than requiring reconfiguration of the entire system, maintaining reliability in targeted areas while reducing overall system complexity.
Solution Approach 2:
The system applies different equalization characteristics to different zones based on their specific acoustic requirements. Each zone can have customized frequency response, gain levels, and signal processing parameters tailored to its local conditions, achieving optimal acoustic performance in each area without affecting other zones, thereby reducing the scope of system reconfiguration needed.

AI summary
Adaptive performance software, operating on a computing device, may be used to control an adaptive loudspeaker system within a venue. In some embodiments, the adaptive performance software may receive a selection of a target area within the venue. The adaptive performance software may then determine a smallest affected zone that includes the target area, and may present the smallest affected zone to the user to indicate what the affected area for the requested changes would be. In some embodiments, the adaptive performance software may take the shape of the venue, the capabilities of the loudspeaker array as configured and flown in the venue, and/or the specific setting changes which are desired in order to determine the smallest affected zone that includes the selected area.
