Work-station with Translucent Acoustic Panels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional work-stations are inefficient in reducing outside sound distractions and providing adequate ambient lighting, leading to feelings of isolation and discomfort among occupants due to their design, which often results in increased energy costs from additional lighting requirements.
Innovation Solution
A work-station with sound-absorbing translucent enclosure walls and a sound masking device that projects sound across the open face, featuring a translucent ceiling and walls allowing for increased ambient light entry while effectively reducing external noise, using panels with strategically placed apertures and struts to enhance sound absorption and light transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If traditional opaque walls are used in work-stations, then sound isolation is improved, but ambient lighting is reduced and energy costs increase
Solution Approach 1:
The patent applies porous acoustic absorption materials to the interior surfaces of the work-station enclosure. These porous materials absorb sound waves entering the enclosure while allowing light to pass through, thus reducing sound distractions without compromising ambient lighting. The porous structure provides sound attenuation through friction and viscous losses as sound waves pass through the material pores.
Solution Approach 2:
The patent employs composite wall constructions combining transparent or translucent materials with acoustic absorption layers. This composite structure allows light transmission while providing sound isolation through the integrated acoustic materials, simultaneously addressing both lighting and sound isolation requirements.
2Object-affected harmful factors
If traditional opaque walls are used in work-stations, then sound isolation is improved, but energy costs increase due to additional lighting requirements
Solution Approach 1:
By using porous acoustic absorption materials that are transparent or translucent, the work-station maintains ambient light levels without requiring additional artificial lighting, thus reducing energy costs while still providing sound isolation.
Solution Approach 2:
The work-station enclosure utilizes the building's existing ambient lighting by employing transparent/translucent acoustic materials, allowing the space to serve its own lighting needs without requiring additional energy-consuming lighting systems.
3Object-affected harmful factors
If sound masking volume is increased to reduce outside sound distractions, then sound masking effectiveness is improved, but conversations in open areas become more difficult
Solution Approach 1:
The patent extracts the sound masking function from the general ceiling area and localizes it to the work-station enclosure itself. By placing acoustic absorption materials directly on the enclosure surfaces, sound treatment is provided at the source rather than through high-volume masking in the open area, preserving conversation clarity.
Solution Approach 2:
The patent applies acoustic treatment locally to each work-station enclosure rather than using uniform high-volume sound masking across the entire open area. This localized approach provides sound isolation where needed while maintaining clear audio transmission in the surrounding open spaces for effective communication.

AI summary
A work-station utilizes sound absorbing, translucent enclosure panels that allows light from outside of the work-station to enter. The translucent enclosure panels have an outside panel, and intermediate panel and an inside panel of a translucent plastic sheet material that form cells for dampening sound transmission through the enclosure panels. The inside panel has a plurality of apertures to allow sound to enter and be dissipated within the internal cells. A sound masking device is configured within the work-station and projects a dampening sound into the work-station, such as along the opening to work-station to produce a masking sound curtain for sound entering the work-station.
