In this section, we’ll delve into the basics of noise cancelling earbuds, exploring their history, technology, and key features.
A Brief History of Noise Cancelling Technology
The concept of noise cancelling technology dates back to the 1950s, when researchers at the Massachusetts Institute of Technology (MIT) discovered that a sound wave can be cancelled out by a wave of the same amplitude and frequency, but with a 180-degree phase shift. This principle is known as destructive interference. In the 1970s and 1980s, noise cancelling technology was first applied to headphones, but they were large and cumbersome, making them impractical for everyday use.
Fast-forward to the 2000s, when noise cancelling earbuds began to emerge as a more portable and convenient alternative. Companies like Bose and Sennheiser pioneered the development of noise cancelling earbuds, incorporating advanced technologies like active noise control and noise reduction algorithms.
How Noise Cancelling Earbuds Work
So, how do noise cancelling earbuds actually work? The process is quite fascinating. Here’s a simplified explanation:
- Microphones:
- Noise cancelling earbuds typically feature one or two microphones, usually located on the outside of the earbuds or on the cable. These microphones pick up ambient noise around you, such as background chatter, traffic, or engine rumble.
