Partition Curtain Layer Layout for Sound Absorption and Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hall dividing curtains fail to achieve satisfactory sound insulation and sound absorption simultaneously, often prioritizing one over the other, leading to inadequate noise reduction in multi-purpose halls like sports and event halls.
Innovation Solution
A partition curtain design featuring alternating absorption and insulation areas within each layer, where absorption areas have higher sound absorption and insulation areas have higher sound insulation, with connecting elements between layers to prevent sound propagation, and utilizing perforated, micro-perforated, or fleece-equipped areas to enhance sound absorption across a broader frequency range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If absorbent material is added to the hall dividing curtain, then sound absorption improves, but weight increases and handling effort increases
Solution Approach 1:
The absorption areas utilize flow-resistant porous materials such as fleece or porous plastic films that provide effective sound absorption while maintaining relatively low weight compared to dense materials. The porosity allows sound waves to penetrate and be absorbed without requiring heavy mass.
Solution Approach 2:
The curtain design changes the flow resistance parameter locally in absorption areas rather than throughout the entire curtain. This targeted parameter modification provides sound absorption where needed while keeping the overall curtain weight manageable by limiting the use of high-flow-resistance materials to specific zones.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design effectively reduces noise transmission by ensuring high sound insulation in absorption areas and high sound absorption in insulation areas, achieving improved acoustic performance with minimal additional effort and expanded frequency range absorption.
Implementation Method 1
The sound absorption is higher in the absorption areas than in the insulation areas
Implementation Method 2
at least one of the curtain panels (3, 7) has a flow-resistant material (5, 9)
Implementation Method 3
The sound insulation is higher in the insulation areas than in the absorption areas

AI summary
The invention relates to a partition curtain (1), in particular for halls, including, for example, sports halls, event halls, trade fair halls and factory halls, with two layers (3, 7). The dividing curtain is characterized in that the layers have absorption areas (4, 6, 9) and insulation areas (5, 8, 10), with the sound absorption in the absorption areas (4, 6, 9) being higher than in the insulation areas (5 , 8, 10), and in the insulation areas (5, 8, 10) the sound insulation is higher than in the absorption areas (4, 6, 9), and the absorption areas (4, 6, 9) of a layer compared to the insulation areas (5 , 8, 10) of the other layer. The acoustic construction depth required for the absorption extends over the entire or almost the entire width of the partition curtain, which leads to a broadband sound absorption of the construction.
