Noise-Canceling Theater Headphones for Personalized Audio Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The audio experience in movie theaters is compromised by ambient noise and excessively high volume levels, with attendees having no control over sound levels, leading to a non-optimal and distracting environment.
Innovation Solution
A system comprising an audio broadcast device, noise-canceling headphones, and an interface device that allows users to select and personalize their audio tracks, reducing ambient noise and enabling volume control through user settings, enabling direct communication between attendees without disturbing others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If stereo sound systems and subwoofer systems are used to enhance audio output, then audio quality is improved, but volume levels become unacceptably high and cause hearing discomfort
Solution Approach 1:
The patent replaces the traditional mechanical speaker-based audio delivery system with an electronic digital audio delivery system using headphones. This substitution allows precise electronic control of volume levels and audio characteristics, eliminating the need for high-power amplification required by speaker systems while maintaining audio quality.
Solution Approach 2:
The system enables individual users to adjust audio parameters including volume level, frequency response, and audio track selection. This parameter customization allows each user to optimize their audio experience according to their hearing sensitivity and preferences, resolving the issue of excessive volume affecting all attendees uniformly.
2Productivity
If movie theaters are designed to hold a substantial number of people to maximize revenue, then productivity is improved, but ambient noise increases and degrades audio experience
Solution Approach 1:
The patent extracts the audio delivery function from the shared theater environment and delivers it individually to each user through headphones. This extraction isolates users from ambient noise generated by other attendees, allowing the theater to maintain high capacity while each user experiences a controlled, quiet audio environment.
Solution Approach 2:
The system segments the audio experience from the shared physical space by providing individualized audio delivery to each attendee. This segmentation allows independent control of audio for each user, eliminating the collective exposure to ambient noise that results from high theater occupancy.
3Object-affected harmful factors
If projectionists adjust volume levels based on attendance to manage sound levels, then excessive volume is reduced, but attendees still have no control over their personal audio experience
Solution Approach 1:
The system enables each attendee to independently control their own audio experience through interface devices connected to their headphones. Users can adjust volume, select audio tracks, and customize audio parameters without requiring projectionist intervention or affecting other attendees,真正实现ing individual self-service audio control.
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 system enhances the audio experience by minimizing ambient noise and allowing personalized audio settings, providing a more enjoyable and controlled listening environment for movie theater attendees.
Implementation Method 1

Data Source
AI summary
A system includes an audio broadcast device, headphones and an interface device. The audio broadcast device may be configured to generate a plurality of audio tracks. The headphones may be configured to perform noise cancellation of ambient audio, decode one of the plurality of audio tracks selected by a user and playback a personalized audio track in response to the selected audio track and user settings. The interface device may be configured to receive the user settings and enable the user to select one of the audio tracks. The headphones may receive the selected audio track from the audio broadcast device in response to the selection using the interface. The user settings may be applied to the selected audio track to generate the personalized audio track.
