Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies have limitations in achieving effective noise reduction and sound attenuation between adjacent rooms in building construction, and existing technologies have not adequately addressed the need for enhanced acoustic performance in building construction, particularly in commercial and residential settings.
Innovation Solution
The development of an acoustic building panel with a porous body and an attenuation coating applied to its surface, featuring a discontinuous pattern of attenuation regions, which enhances sound absorption and attenuation properties without compromising airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a dense attenuation coating is applied to the entire surface of the building panel, then sound attenuation performance is improved, but airflow through the panel is blocked
Solution Approach 1:
The attenuation coating is applied in a discontinuous pattern rather than as a continuous layer, segmenting the coating into discrete regions that provide sound attenuation while leaving gaps for airflow. This segmentation allows the panel to simultaneously achieve sound blocking and air permeability.
Solution Approach 2:
Different regions of the panel surface have different properties: some areas have attenuation coating applied while other areas remain without coating. This local differentiation allows specific zones to provide sound attenuation while other zones maintain airflow pathways, resolving the contradiction between sound blocking and air permeability.
2Object-affected harmful factors
If previous acoustic panel technologies are used, then some noise reduction is achieved, but the maximum sound attenuation is limited and insufficient for enhanced acoustic performance
Solution Approach 1:
The building panel combines the base panel material with an attenuation coating applied in a discontinuous pattern, creating a composite structure that leverages the advantages of both materials. This composite approach enables superior sound attenuation performance that exceeds previous acoustic panel technologies while maintaining air permeability.
