Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sound transmission reduction systems between adjacent volumes are inefficient due to the direct transmission of acoustic energy through supporting beams and mountings, which limits the effectiveness of soundproofing.
Innovation Solution
A system comprising novel supporting beams with folds that define pockets for mounting sound panels and brackets with voids to reduce acoustic energy transmission, along with sound panels and auxiliary panels designed to absorb and disperse sound, is introduced to minimize energy transfer between wall surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If solid materials and massive wall surfaces are used to reduce sound transmission, then acoustic energy transmission is reduced, but the structure becomes heavier and more complex
Solution Approach 1:
The patent employs composite construction by combining multiple materials with different acoustic properties: sound-absorbing panels with fibrous or porous materials, rigid framing members, and resilient mounting elements. This layered composite structure achieves effective sound transmission reduction without requiring uniformly massive walls, as each layer contributes differently to the overall acoustic performance.
Solution Approach 2:
The patent utilizes porous and fibrous materials in the sound-absorbing panels to dissipate acoustic energy through friction and viscous effects within the porous structure. These materials convert acoustic energy into thermal energy through viscous dissipation, providing effective sound absorption without the need for massive solid materials.
2Ease of manufacture
If sound panels are mounted directly to structural beams, then installation is simplified, but acoustic energy transmits through the mountings
Solution Approach 1:
The patent introduces resilient mounting elements as intermediaries between the sound panels and the structural beams. These resilient elements act as acoustic decouplers, breaking the direct transmission path while maintaining mechanical support. The resilient nature of these intermediaries allows them to vibrate independently, preventing the transmission of acoustic energy from one side of the wall to the other.
Solution Approach 2:
The resilient mounting elements are pre-installed on the structural beams before the sound panels are attached. These elements provide beforehand cushioning by creating a compliant interface that absorbs and dissipates acoustic energy before it can reach the panel mounting interface, thereby preventing transmission through the mounting structure.
3Strength
If vertically extending supporting beams are used for wall construction, then structural strength is improved, but acoustic energy is efficiently transmitted through them
Solution Approach 1:
The patent introduces resilient mounting elements as intermediaries between the sound panels and the vertically extending supporting beams. These resilient elements decouple the acoustic transmission path from the structural beams, allowing the beams to maintain their structural strength while preventing efficient acoustic energy transmission through them.
Solution Approach 2:
The patent employs resilient mounting elements that function as flexible acoustic barriers. These flexible elements can deform and vibrate independently, creating a flexible barrier that blocks acoustic energy transmission while allowing the rigid structural beams to maintain their strength.
4Object-affected harmful factors
If plural spaced apart walls are used to eliminate vibration transmission, then acoustic energy transmission is reduced, but the space required increases
Solution Approach 1:
The patent segments the wall assembly into distinct functional layers: structural framing, sound-absorbing panels, and resilient mounting elements. This segmentation allows each layer to perform its specific function independently, achieving effective vibration transmission reduction within a compact overall thickness without requiring the large spacing between separate walls.

The multiplicity of pores between adjacent fibers enable sound and/or noise to enter through the multiplicity of pores and to be dispersed by the multiplicity of fibers within the sound absorbing member
Implementation Method 2
