Resilient Noise Damper for Suspended Ceiling Hangers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for noise control in suspended ceilings are time and labor-intensive due to the need for manual cutting, threading, and twisting of wire hangers to install noise attenuators, which complicates the installation process and requires significant effort to secure sound-damping materials between structural and grid beams.
Innovation Solution
A noise damper made of resilient material is inserted between the grid beam and the hanger, distributing stress and deadening sound vibrations without interfering with the structural support, allowing for a single length of hanger to be used and reducing installation time by eliminating the need for additional attachments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If prior art noise attenuators are installed by dividing the wire hanger into two segments and securing each segment to the attenuator, then sound vibration damping is achieved, but installation time and labor effort increase significantly
Solution Approach 1:
The noise damper is extracted as a separate component that is attached to the grid beam, allowing the wire hanger to remain as a single continuous segment. The hanger is simply looped through the damper's opening and twisted closed, eliminating the need to divide the hanger into segments and attach each segment to separate attenuator terminals.
Solution Approach 2:
The noise damper acts as an intermediary component between the wire hanger and the grid beam. It provides a mounting structure with an opening that the hanger can pass through, serving as a mediator that connects the suspension system while providing sound vibration damping without requiring complex attachment procedures.
2Object-affected harmful factors
If noise attenuators are installed with additional attachment steps involving threading and twisting, then sound damping is provided, but device complexity and installation difficulty increase
Solution Approach 1:
The complex attachment mechanism is extracted from the noise control function. Instead of integrating the damping material into terminals that require threading and twisting, the damping function is separated into a standalone damper body with a simple opening that accepts the hanger in a single straightforward operation.
Solution Approach 2:
The noise damper concentrates the sound damping function in a localized component with a specific opening geometry designed for easy hanger insertion. The local structure of the damper's opening and body provides the necessary sound attenuation while maintaining simplicity of installation through its geometric design.
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
The noise damper effectively deadens sound vibrations while maintaining structural support, allowing for faster installation comparable to standard suspended ceilings without noise damping, and can be easily integrated into existing construction processes.
Implementation Method 1
Sound vibrations coming down the wire hanger sound path from the structural ceiling are absorbed in the noise attenuator
Implementation Method 2
A noise damper, of material that deadens sound vibrations coming down a hanger

AI summary
Noise dampers of sound absorbent material are inserted on the metal grid beams in a suspended ceiling.Hangers, embedded in a structural ceiling, that support the beams, are insulated from the beams by the noise dampers.Sound vibrations generated in the structural ceiling, which is often a floor, are not transmitted through the hangers, to the suspended ceiling, or to the room, below, but are absorbed in the dampers before reaching the grid beams.
