英文回答：
Noise Canceller.
Noise cancellers are devices that help reduce or eliminate unwanted sounds or noises. They use advanced technology to analyze the incoming sounds and generate an opposite sound wave to cancel out the noise. This is achieved by using microphones to pick up the incoming sound waves and then producing a sound wave that is 180 degrees out of phase with the unwanted noise. When these two waves combine, they cancel each other out, resulting in a quieter environment.
There are different types of noise cancellers available in the market. One common type is the active noise canceller, which is often used in headphones. These headphones have built-in microphones that pick up the ambient noise and generate the opposite sound wave to
cancel it out. This allows the listener to enjoy their
music or audio content without being disturbed by external noises.
Another type of noise canceller is the passive noise canceller, which is often used in buildings or rooms. This type of noise canceller works by using materials that
absorb or block sound waves. For example, soundproof
curtains or acoustic panels can be used to reduce the noise level in a room. These materials absorb the sound waves, preventing them from bouncing off walls and creating echoes or reverberations.
Noise cancellers have various applications in different industries. In aviation, noise cancellers are used to
reduce noise in aircraft cabins, making the flying experience more comfortable for passengers. In construction, noise cancellers are used to minimize the impact of loud noises on nearby residents. In offices, noise cancellers
can be used to create a quieter and more productive working environment.
Overall, noise cancellers are effective tools for reducing unwanted noises and creating a more peaceful environment. Whether it's for personal use, in buildings,
or in transportation, noise cancellers play a crucial role
in enhancing our comfort and well-being.

噪音消失器。

噪音消失器是一种帮助减少或消除不需要的声音或噪音的设备。

它们使用先进的技术来分析输入的声音，并产生相反的声波来抵消
噪音。

这是通过使用麦克风来接收输入的声波，然后产生与不需要
的噪音相位差180度的声波来实现的。

当这两个声波相结合时，它
们相互抵消，从而使环境更加安静。

市场上有不同类型的噪音消失器。

一种常见的类型是主动噪音
消失器，通常用于耳机中。

这些耳机内置了麦克风，可以接收环境
噪音并产生相反的声波来抵消它。

这使得听者可以在不受外部噪音
干扰的情况下享受音乐或音频内容。

另一种类型的噪音消失器是被动噪音消失器，通常用于建筑物
或房间。

这种类型的噪音消失器通过使用吸收或阻挡声波的材料来工作。

例如，隔音窗帘或声学板可以用来降低房间的噪音水平。

这些材料吸收声波，防止其反射在墙壁上产生回声或共鸣。

噪音消失器在不同行业中有各种应用。

在航空业中，噪音消失器用于减少飞机舱内的噪音，使乘客的飞行体验更加舒适。

在建筑业中，噪音消失器用于减少噪音对附近居民的影响。

在办公室中，噪音消失器可以用来创造一个更安静、更有生产力的工作环境。

总的来说，噪音消失器是减少不需要的噪音、创造更宁静环境的有效工具。

无论是个人使用、建筑物还是交通工具中，噪音消失器在提升我们的舒适度和福祉方面发挥着重要作用。
