关于噪音消失器作文500字
英文回答：
Noise Canceller.
Noise is an inevitable part of our daily lives. Whether
it's the sound of traffic on the streets or the chatter of
people in a crowded room, noise can be distracting and
irritating. Fortunately, there is a solution to this
problem the noise canceller.
A noise canceller is a device that is designed to
reduce or eliminate unwanted noise. It works by producing a
sound wave that is the exact opposite of the unwanted noise,
thus canceling it out. This technology is based on the
principle of destructive interference, where two waves of
equal amplitude and opposite phase cancel each other out.
The noise canceller consists of a microphone, a signal
processor, and a speaker. The microphone picks up the
unwanted noise and sends the signal to the processor. The
processor analyzes the signal and generates a sound wave
that is the exact opposite of the unwanted noise. This
sound wave is then played through the speaker, effectively
canceling out the noise.
Noise cancellers have a wide range of applications.
They are commonly used in headphones to provide a quieter
and more immersive listening experience. They are also used
in aircraft cabins to reduce the noise from the engines,
making the flight more comfortable for passengers.
Additionally, noise cancellers are used in industrial
settings to protect workers from excessive noise exposure.
