Remote Microphone Volume Limiting for Quiet Media Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Media devices often produce audio output volumes that can disturb others, particularly in unsupervised scenarios or during specific times, such as early mornings or late nights, leading to annoyance or disturbance for household members or neighbors.
Innovation Solution
A system and method that uses a remotely located microphone to detect audio output levels from media devices, compares them to a predefined maximum volume limit, and generates a command to reduce the volume when exceeded, allowing for user-defined time-based volume limitations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user controls volume freely without supervision, then ease of operation is improved, but harmful noise disturbance to others increases
Solution Approach 1:
The system uses a microphone to detect the actual audio output from the media presentation device and feeds this information back to a controller. The controller compares the detected sound level against a predetermined maximum volume threshold and automatically generates volume limit commands when the threshold is exceeded, creating a closed-loop feedback system that prevents harmful noise without requiring constant user supervision
Solution Approach 2:
The volume limiting system operates autonomously by automatically detecting audio levels, comparing them to thresholds, and adjusting volume without requiring user intervention. The controller self-manages the volume control function by generating and transmitting volume limit commands to the media presentation device based on real-time acoustic feedback
2Object-generated harmful factors
If volume is limited during specific periods, then harmful noise disturbance is reduced, but adaptability to different usage scenarios decreases
Solution Approach 1:
The system dynamically adjusts volume limits based on time-of-day parameters. Different maximum volume thresholds are applied at different times: a first (stricter) volume limit during nighttime hours when disturbance is more harmful, and a second (more permissive) volume limit during daytime hours. This dynamic adaptation allows the system to balance noise prevention with usage flexibility according to contextual conditions

AI summary
Volume limiting systems and methods are operable to limit volume output from media presentation devices. An exemplary embodiment detects a sound using a microphone, wherein the sound corresponds to an audio output of at least one controlled media presentation device, and wherein the microphone is remotely located from the at least one controlled media presentation device; compares a level of the detected sound with a predefined maximum volume limit; generates a volume output limit command in response to the detected sound exceeding the predefined maximum volume limit; and communicates the volume output limit command to the media presentation device. The media presentation device then reduces a volume level of its audio output. In some instances, volume may be limited during user specified periods.
