Office Pod Soundproofing Wall Structure with High Coincidence Frequency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional office pods have become increasingly expensive to manufacture while maintaining soundproofing effectiveness, particularly at human speech frequencies.
Innovation Solution
The office pod incorporates a soundproofing wall structure composed of a sound absorbing element and a skin layer, where the skin layer has a coincidence frequency outside the human speech frequency region, typically above 5 kHz, to enhance sound stopping effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional office pods use traditional wall modules with multiple sound stopping and sound absorbing layers, then soundproofing effectiveness is maintained, but manufacturing cost increases
Solution Approach 1:
The patent changes the coincidence frequency parameter of the skin layer to be above the human speech frequency region (typically above 5 kHz), which fundamentally alters how the wall structure blocks sound. This parameter change allows the use of simpler, less expensive materials while maintaining soundproofing effectiveness at speech frequencies, resolving the contradiction between soundproofing performance and manufacturing cost
Solution Approach 2:
The patent employs a composite wall structure combining a skin layer with specific acoustic properties and sound absorbing material layers. The skin layer is designed with a coincidence frequency above the human speech frequency region, creating a composite structure that is both cost-effective and acoustically performant, addressing the contradiction between cost and soundproofing effectiveness
2Reliability
If the skin layer has a coincidence frequency above human speech frequency region, then sound stopping effect at speech frequencies is improved, but the wall structure becomes more complex
Solution Approach 1:
By adjusting the coincidence frequency parameter of the skin layer to be above the human speech frequency region, the patent achieves superior sound stopping at speech frequencies without requiring complex multi-layer constructions. This single parameter change simplifies the overall wall structure while improving acoustic performance
3Reliability
If the sound absorbing element has greater thickness, then soundproofing at human speech frequencies is improved, but the office pod volume increases
Solution Approach 1:
The patent changes the coincidence frequency parameter of the skin layer to be above the human speech frequency region, which allows achieving effective soundproofing with thinner wall structures. This parameter change eliminates the need for thick sound absorbing elements, thereby maintaining compact office pod volume while preserving soundproofing performance
