directional microphone การใช้

• Efforts to build directional microphones based on the coupled-eardrum structure are underway.
• Most external microphone designs are of either bi-directional microphone as elements.
• Many hearing aids now have both an omnidirectional and a directional microphone mode.
• Like all directional microphones, the SM58 is subject to wireless versions.
• Despite the disadvantages, adaptive directional microphones can provide improved speech recognition in noise
• The directional microphone, although placed at your ear, picks up sounds from your mouth.
• Some cameras are equipped with directional microphones that can pick up even whispered conversations.
• Directional microphones do significantly improve the signal to noise ratio.
• You can use a highly directional microphone to record only one person at a time.
• It has a directional microphone, a larger library of phrases and a longer battery life.
• A bi-directional microphone's receptive field has two angles only.
• A special directional microphone mounted on the sun visor on the driver's side picks up the commands.
• Imagine a very sensitive, highly directional microphone, maybe hovering in a drone aircraft high above a city.
• The microphone uses four directional microphones and digital signal processors to distinguish your commands from your dog's barking.
• Specific technologies may include long-range directional microphones, infrared night-vision and motion-activated cameras, underwater cameras, and small fiber-optic endoscopic cameras.
• Directional microphones'frequency response varies greatly with distance from the sound source, and with the geometry of the sound source.
• Directional microphones should be used in most cases, in order to isolate a speaker's voice from other potential noise sources.
• And for the most part, screening out unwanted sounds has involved either bulky and hard-to-use directional microphones or inconvenient headsets.
• Highly-directional microphones "'are "'the way everyone does it, using techniques such as " shotgun " microphones and parabolic reflectors plus microphones.
• Adaptive directional microphones automatically vary the direction of maximum amplification or rejection ( to reduce an interfering directional sound source ).
