Automated Ambient Noise Reduction for Online Meetings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home environments often introduce disruptive ambient noises during online meetings, which can't be easily managed before a meeting starts, as they differ from office settings and may include loud appliances or other distractions.
Innovation Solution
A system that automatically detects and mitigates ambient noises by sending signals to smart appliances to pause or power down when an online meeting begins, using a collaboration service to control devices like washers, dryers, sound systems, and TVs, and employs noise cancellation techniques for living sounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If smart appliances operate continuously in home environments, then appliance functionality and convenience are maintained, but ambient noise disrupts online meetings
Solution Approach 1:
The system performs preliminary action by detecting the start of an online meeting before the meeting fully begins and proactively pausing smart appliances to prevent noise disruption. The collaboration service monitors for meeting initiation signals and triggers appliance pause commands in advance, ensuring noise-free meeting environment from the start.
Solution Approach 2:
The system implements feedback by continuously monitoring meeting status through the collaboration service and adjusting appliance operation accordingly. When a meeting is detected, the system receives feedback signals and automatically responds by pausing appliances; when the meeting ends, the system resumes appliance operation, creating a closed-loop control system that adapts to meeting conditions.
2Object-affected harmful factors
If smart appliances are paused during meetings, then ambient noise is reduced, but appliance functionality is interrupted
Solution Approach 1:
The system applies dynamics by making appliance operation state changeable based on meeting conditions. Appliances transition between operating and paused states dynamically according to real-time meeting detection, allowing the system to adapt appliance behavior to current usage context rather than maintaining a fixed operational state.
Solution Approach 2:
The system applies preliminary anti-action by pausing appliances before they can generate disruptive noise during meetings. By detecting meeting start in advance and preemptively pausing appliances, the system prevents noise disruption before it occurs, rather than reacting after noise has already disturbed the meeting.
3Object-affected harmful factors
If manual control of appliances is required during meetings, then noise can be managed, but user convenience and automation are reduced
Solution Approach 1:
The system implements self-service by enabling smart appliances to automatically adjust their own operation based on meeting detection signals from the collaboration service. Appliances receive automated pause and resume commands without requiring manual user intervention, allowing the system to manage itself in response to meeting conditions.
Solution Approach 2:
The collaboration service acts as a universal controller that manages multiple different types of smart appliances through a single integrated system. The service can pause various appliances (washing machines, dryers, dishwashers, etc.) using standardized control protocols, providing multi-functional noise management across diverse device types.

AI summary
A system and method for addressing distracting ambient noise during online collaborative meetings monitors when an online meeting is entered by a user at their computer. Smart devices are automatically powered down, paused or otherwise controlled during the online meeting. Devices are returned to their former state once the user leaves the meeting.
