Dental Sound Control System for Patient Noise and Voice Clarity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental treatments often create discomfort for patients due to high-frequency noise, and existing noise cancellation technologies are not effectively applied in dental environments to facilitate communication between patients and medical staff.
Innovation Solution
A sound control system comprising ear-worn speakers, a microphone, a voice recognition module, a sound source module, and an output signal generation module, which allows patients to select calming sound sources and ensures the voice of medical staff is clearly transmitted while reducing ambient noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If active noise control technology is applied to headphones or earphones, then noise blocking capability is improved, but communication between patient and medical staff deteriorates
Solution Approach 1:
The system dynamically adjusts the noise control mode based on detected voice signals. When medical staff speech is detected, the system switches from active noise cancellation to voice transmission mode, allowing real-time communication while maintaining noise blocking during non-communication periods
Solution Approach 2:
The system uses a microphone to detect ambient sounds and voice signals, providing feedback to the control algorithm. This feedback mechanism enables the system to distinguish between harmful noise and useful voice communications, adjusting its response accordingly to maintain both noise blocking and communication capabilities
2Productivity
If high-frequency noise is generated during dental treatment, then treatment effectiveness is improved, but patient comfort deteriorates
Solution Approach 1:
The system converts the harmful high-frequency noise generated during dental treatment into a controlled audio output. By using ear-worn speakers to deliver customized sound content, the system transforms the noisy environment into a beneficial auditory experience that promotes patient relaxation and comfort while allowing treatment to proceed effectively
3Object-affected harmful factors
If calming sound sources are played through ear-worn speakers, then patient relaxation is improved, but voice transmission from medical staff deteriorates
Solution Approach 1:
The system dynamically switches between sound playback mode and voice transmission mode. During normal treatment, calming sounds are played for patient relaxation. When the microphone detects medical staff speech, the system transitions to voice transmission mode, ensuring clear communication while maintaining patient comfort during non-communication periods
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 enables patients to receive dental treatment in a more relaxed state with reduced noise and effective communication, allowing for smoother treatment processes by mixing preferred sound sources and prioritizing the voice of the medical staff.
Implementation Method 1
a microphone that converts, into an electrical signal, a sound including a voice of a medical staff in charge of the patient
Implementation Method 2
ear-worn speakers equipped to be worn by a patient in the dentist
