1Object-affected harmful factors
If manual control of volume keys is used to adjust noise levels, then noise interference can be avoided, but the operation becomes cumbersome and user experience deteriorates
Solution Approach 1:
The system enables devices to automatically detect ambient noise levels and adjust their own volume without manual user intervention. The noise detecting unit continuously monitors the environment and the controlling unit automatically sends adjustment commands to affected devices, making the noise control system serve itself rather than requiring user operation.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where the noise detecting unit continuously monitors ambient noise levels, compares them against threshold values, and triggers automatic volume adjustments through the controlling unit. This real-time feedback loop ensures noise levels are continuously optimized without requiring manual user input.
2Extent of automation
If automatic noise detection and control is implemented, then user experience is improved and operation is simplified, but device complexity increases
Solution Approach 1:
The noise control system is divided into distinct functional modules: a noise detecting unit for monitoring ambient sound levels, a controlling unit for processing detection results and generating control commands, and multiple controlled devices that receive and execute volume adjustment commands. This segmentation allows each component to have a specific, simplified function while achieving complex overall behavior through their coordination.
Solution Approach 2:
The controlling unit serves multiple functions: it receives noise level data from the detecting unit, compares it against threshold values, determines which devices need adjustment, generates appropriate control commands, and transmits them to the relevant controlled devices. This multi-functionality reduces the need for separate dedicated components for each task, thereby managing system complexity.
3Measurement precision
If continuous noise monitoring is performed, then noise control accuracy is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous monitoring, the noise detecting unit performs periodic noise level measurements at predetermined intervals. The system compares the current noise level with previously recorded levels and only triggers volume adjustments when significant changes are detected, thereby reducing unnecessary energy consumption while maintaining adequate noise control accuracy.
