designing a near-field Bluetooth remote control that operates within 5cm, selecting the right microphone is essential for clear voice capture and effective noise cancellation. Microphone Directionality Comparison In close-range applications, the microphone&#8217;s directional pattern significantly affects noise rejection performance: Feature Unidirectional Microphone Bidirectional Microphone Pickup Pattern Front-focused Front and rear Noise Rejection Excellent from sides\/rear Good from sides only Close-Talk Performance Optimal, minimal breath noise May capture breath\/plosives Best For Remote controls, headsets Interviews, conversations Recommended Solution For near-field Bluetooth remote controls, we recommend the&nbsp;unidirectional ECM-B1045UML50-25082&nbsp;electret condenser microphone.
