Noise cancelling headphones have become increasingly popular in recent years, and for good reason. They offer a unique combination of comfort, sound quality, and noise reduction that makes them ideal for commuters, travelers, and anyone who wants to immerse themselves in their music or work without distractions. But one question that many people have about noise cancelling headphones is whether they can cancel out voices. In this article, we’ll delve into the world of noise cancelling technology and explore the answer to this question in detail.
How Noise Cancelling Headphones Work
Before we can understand whether noise cancelling headphones can cancel out voices, we need to understand how they work. Noise cancelling headphones use a technology called active noise control, which involves the use of one or more microphones to capture ambient noise, and then producing a “negative” sound wave to cancel it out. This process is called destructive interference, and it’s the key to how noise cancelling headphones are able to reduce background noise.
The process works as follows: the microphone in the headphones picks up ambient noise, such as the sound of an airplane engine or the hum of a computer. The headphones then use an electronic circuit to generate a “negative” sound wave that is the exact opposite of the ambient noise. When the two sound waves meet, they cancel each other out, resulting in a quieter listening experience.
The Types of Noise That Can Be Cancelled
Noise cancelling headphones are most effective at cancelling out constant, low-frequency sounds such as the hum of a engine or the rumble of a plane. These types of sounds are often referred to as “steady-state” noises, and they are the easiest for noise cancelling headphones to eliminate. However, noise cancelling headphones are not as effective at cancelling out high-frequency sounds, such as the sound of voices or the rustling of papers. This is because high-frequency sounds are more complex and varied, making them harder for the noise cancelling circuitry to anticipate and cancel out.
The Limitations of Noise Cancelling Technology
While noise cancelling headphones are incredibly effective at reducing background noise, they are not perfect. There are several limitations to the technology that can affect their ability to cancel out voices. For example, noise cancelling headphones are not as effective in noisy environments with a lot of high-frequency sounds, such as airports or shopping malls. They are also not as effective at cancelling out sounds that are close to the listener, such as the sound of someone talking next to them.
In addition, noise cancelling headphones can sometimes produce a phenomenon called “occlusion,” which is a feeling of pressure or discomfort in the ears. This can be caused by the noise cancelling circuitry, which can sometimes produce a slight hissing or humming sound. Occlusion can be uncomfortable and may even cause some listeners to experience headaches or ear fatigue.
Can Noise Cancelling Headphones Cancel Out Voices?
So, can noise cancelling headphones cancel out voices? The answer is no, not completely. While noise cancelling headphones can reduce the volume of voices and other high-frequency sounds, they are not able to completely eliminate them. This is because voices are a type of high-frequency sound that is more complex and varied than the steady-state noises that noise cancelling headphones are designed to eliminate.
However, some noise cancelling headphones are better than others at reducing the volume of voices. For example, headphones with advanced noise cancelling technology, such as adaptive noise cancelling or noise cancelling with multiple microphones, may be more effective at reducing the volume of voices. Additionally, some headphones may have a feature called “voice mode” or “conversation mode” that allows the listener to hear voices more clearly, even when the noise cancelling is turned on.
Real-World Examples of Noise Cancelling Headphones
To give you a better idea of how noise cancelling headphones perform in real-world situations, let’s take a look at a few examples. For instance, the Bose QuietComfort 35 II is a popular noise cancelling headphone that is known for its advanced noise cancelling technology. In a quiet office environment, the Bose QuietComfort 35 II is able to reduce the volume of background noise, including voices, by up to 70%. However, in a noisy environment like an airport, the headphones may only be able to reduce the volume of voices by 30-40%.
Another example is the Sony WH-1000XM4, which is a highly-rated noise cancelling headphone that uses advanced noise cancelling technology with multiple microphones. In a crowded coffee shop, the Sony WH-1000XM4 is able to reduce the volume of background noise, including voices, by up to 50%. However, in a quiet library, the headphones may only be able to reduce the volume of voices by 20-30%.
Conclusion
In conclusion, noise cancelling headphones are not able to completely cancel out voices, but they can reduce the volume of voices and other high-frequency sounds. The effectiveness of noise cancelling headphones at reducing voices depends on the type of noise cancelling technology used, as well as the environment in which they are being used. While noise cancelling headphones are not perfect, they can still be a valuable tool for anyone who wants to reduce background noise and immerse themselves in their music or work.
It’s worth noting that there are some noise cancelling headphones that are specifically designed to reduce the volume of voices, such as headphones with advanced noise cancelling technology or headphones with a feature called “voice mode” or “conversation mode”. These headphones may be more effective at reducing the volume of voices, but they may also be more expensive than other noise cancelling headphones.
Ultimately, the decision to purchase noise cancelling headphones depends on your individual needs and preferences. If you’re looking for a way to reduce background noise and immerse yourself in your music or work, noise cancelling headphones may be a good option for you. However, if you’re looking for a way to completely eliminate voices and other high-frequency sounds, you may want to consider other options, such as earplugs or earmuffs.

While they may not be able to completely cancel out voices, they can still be effective at reducing the volume of voices and other high-frequency sounds. By understanding how noise cancelling headphones work and what to expect from them, you can make an informed decision about whether they are right for you.
How do noise-cancelling headphones work?
Noise-cancelling headphones use a technology called active noise control to reduce unwanted ambient sounds. This technology works by using one or more microphones to capture ambient noise, and then producing a “negative” sound wave to cancel it out. The microphone(s) are usually located on the outer shell of the headphones, and they pick up the ambient noise around the listener. The noise-cancelling circuitry then generates an “anti-noise” signal, which is the exact opposite of the ambient noise, and plays it through the headphones’ speakers.
The combination of the ambient noise and the anti-noise signal results in the cancellation of the noise, leaving the listener with a quieter and more peaceful listening experience. Noise-cancelling headphones can be effective in reducing constant, low-frequency sounds such as the hum of an engine, the rumble of traffic, or the whir of a fan. However, they may not be as effective in reducing high-frequency sounds or sudden, sharp noises like voices or screams. The effectiveness of noise-cancelling headphones also depends on the quality of the headphones, the type of noise being cancelled, and the listening environment.
