In our daily lives, we’re surrounded by sounds. From the hum of traffic to the buzz of a crowded room, noise is everywhere. But what if you could press a button and mute the world around you? That’s where noise cancelling technology comes in—a modern solution to an age-old problem. This guide will explore noise cancellation, how it works, and introduce you to Krisp, a software that’s changing the game in noise reduction.
What is Noise Cancellation?
Noise cancellation is a technology designed to reduce unwanted sound. Whether it’s for enjoying music, enhancing concentration, or ensuring clearer conversations, noise cancellation makes it possible to tune out distractions and focus on what matters.
How Does Noise Cancelling Work?
Noise cancellation operates through different methods, each tailored to combat noise in unique ways. Let’s look at the main types:
Passive Noise Cancellation
Passive noise cancellation is about creating a physical barrier that blocks external sounds. This can be as simple as the design of over-ear headphones that naturally muffle noises. It’s straightforward and effective for blocking out general ambient sounds.
Active Noise Cancellation (ANC)
Active noise cancellation takes a more sophisticated approach. It involves using microphones to pick up external noise and then producing a counter sound wave that neutralizes the noise. This “anti-noise” process is particularly effective against low-frequency sounds, such as the drone of an airplane engine. AirPods, for instance, have an Active Noise Cancellation mode. This relies on an outward-facing mic that analyzes and detects noise coming from the outside and an inward-facing mic that listens for and cancels noises that escape from the external mic.
Tip: We’ve got a step-by-step guide to help you decide which headphones are the right ones for your different use cases.
Adaptive Noise Cancellation
Adaptive noise cancellation builds on ANC by adjusting to changing noise environments in real-time. This ensures the level of noise reduction is always optimized, whether you’re in a quiet library or a noisy café.
Adjustable Noise Cancellation
With adjustable noise cancellation, you have the power to control how much of the outside world you let in. This feature is great for maintaining awareness of your surroundings while still enjoying the benefits of noise cancellation.
Transparency Mode
Transparency mode, sometimes called ambient mode, allows you to hear important sounds around you without removing your headphones. It’s a smart feature for those who want to stay connected to their environment.
Key Differences Between Noise Cancelling Methods
To give you a clearer picture, here’s a quick comparison:
| Type | How It Works | Best For |
|---|---|---|
| Passive | Blocks noise with physical barriers | High-pitch noise |
| Active (ANC) | Uses special anti-noise sound waves to cancel noise | Low, rumbling noise |
| Adaptive | Adjusts to noise in real-time | Changing noise environments |
| Adjustable | Lets you control noise levels | Personal preference |
| Transparency | Lets outside sounds in | Staying aware of the surroundings |
Taking It a Step Further: Noise Cancelling Software
But noise-cancelling headphones don’t fix all of your problems. While you won’t hear your dog barking or electronic devices making buzzing sounds, others will.
That’s where new systems come in to end the noise problem.
While hardware-based solutions have significantly advanced noise cancellation, software solutions like Krisp represent a paradigm shift. Krisp utilizes artificial intelligence to identify and filter out background noise in real-time, offering a software-based approach to noise cancellation. This method is particularly useful in communication applications, ensuring clear audio transmission in calls and recordings, irrespective of environmental noise.
