Introduction to Noise Cancelling
Noise cancelling, on the other hand, is a technology designed to eliminate unwanted background noise. It works by using one or more microphones to capture ambient sound, and then producing a “negative” sound wave to cancel it out. Noise cancelling is commonly used in headphones and earbuds, allowing listeners to focus on the music or other audio without distractions. Noise cancelling can be particularly useful in loud environments, such as on airplanes or in busy cities, where background noise can be overwhelming.
How Noise Cancelling Works
Noise cancelling technology uses a process called destructive interference to eliminate ambient sound. Here’s how it works:
The Process of Noise Cancelling
- One or more microphones capture the ambient sound around the listener.
- The microphone sends the sound signal to a processor, which analyzes the sound wave and generates a “negative” sound wave.
- The negative sound wave is then played through the headphones or earbuds, cancelling out the ambient sound.
- The result is a quieter, more peaceful listening experience, with minimal background noise.
