Let’s take a closer look at the steps involved in this fascinating technology.
1. Microphones: Noise cancelling headphones are equipped with built-in microphones that pick up ambient sounds from the environment. These microphones capture the unwanted noise, converting it into an electrical signal.
2. Noise cancellation circuitry: Once the microphones detect the ambient noise, the electrical signal is processed by the noise cancellation circuitry. This circuitry analyzes the frequency and amplitude of the external sounds to determine the appropriate response.
3. Inverted sound wave: Based on the analysis of the ambient noise, the headphones generate an inverted sound wave. This inverted wave is designed to have the same amplitude as the original sound wave but with an opposite phase.
4. Combining sound waves: The original sound wave and the inverted sound wave are combined using a process known as superposition. When the two waves meet, they effectively cancel each other out, reducing or eliminating the external noise.
5. Output to the user: The resulting sound, after the cancellation process, is then delivered to the user’s ears. This allows for a more focused and immersive audio experience, with minimal interference from unwanted sounds.
It’s important to note that noise cancelling technology is most effective for steady, low-frequency sounds like engine noises or background chatter. Sudden or high-pitched sounds may not be completely eliminated by noise cancellation alone, but the technology can still help reduce their impact.
In addition to active noise cancellation, some headphones also utilize passive noise cancellation methods. Passive noise cancellation involves physical components, such as thick ear cushions or in-ear tips, that create a barrier between the user’s ears and the external environment. Together, active and passive noise cancellation work in tandem to maximize noise reduction.
In the next section, we will explore the specific noise cancelling technology utilized by Bose headphones and how it contributes to their premium audio experience.

Active noise cancellation
Active noise cancellation (ANC) is a key technology used in noise cancelling headphones, including those manufactured by Bose. ANC works by actively counteracting external sounds to create a more peaceful and immersive listening experience. Let’s dive deeper into how active noise cancellation works and the benefits it offers.
Active noise cancellation involves three main components: microphones, noise cancelling circuitry, and speakers. The microphones in the headphones detect ambient sounds and convert them into electrical signals. These signals are then processed by the noise cancelling circuitry, which analyzes the frequency and amplitude of the incoming noise.
Once the circuitry identifies the characteristics of the ambient noise, it generates an inverted sound wave with the same amplitude but an opposite phase. This inverted wave is then played through the headphones’ speakers alongside the original audio content.
When the original sound wave and the inverted wave combine, they interact in a way that cancels out the external noise. This cancellation effect occurs because the peaks of the original wave align with the troughs of the inverted wave, effectively neutralizing the sound waves arriving at the listener’s ears.
The effectiveness of active noise cancellation can vary depending on the quality of the headphones and the ambient noises present. It is particularly effective at reducing low-frequency sounds, such as the hum of airplane engines, traffic noise, or air conditioners.
Bose is known for its industry-leading ANC technology, which continuously adapts and improves with each new headphone iteration.

Passive noise cancellation
In addition to active noise cancellation, another method used to reduce unwanted external sounds in headphones is passive noise cancellation. While active noise cancellation uses electronic systems to actively counteract noise, passive noise cancellation relies on physical barriers to block or minimize sound waves. Let’s explore how passive noise cancellation works and its benefits.
Passive noise cancellation is achieved through the design and construction of the headphones themselves. The materials and structure of the headphones are engineered to reduce the amount of external noise that reaches the listener’s ears.
One of the primary ways passive noise cancellation is achieved is through the use of earcups or ear tips that form a tight seal around the ears. These cushions or tips act as physical barriers, preventing sound waves from entering the ear canal. The seal helps block out ambient noise, providing a quieter listening environment.
The materials used in the construction of the headphones also play a role in passive noise cancellation. High-density foam or other sound-absorbing materials are often used in the earcups to trap or absorb sound waves. These materials help to reduce the transmission of external noise to the listener’s ears.
The physical design of the headphone enclosure can also contribute to passive noise cancellation. Over-ear headphones, for example, cover the entire ear and create a larger sound barrier compared to on-ear or in-ear designs. The larger the barrier, the more external noise can be blocked, resulting in a quieter audio experience.
Passive noise cancellation is particularly effective in reducing higher frequency sounds, such as human voices or sharp noises. However, it may not be as effective in mitigating low-frequency sounds, such as engine rumble or bass vibrations.
Passive noise cancellation can be a great complement to active noise cancellation. By combining both methods, headphones can provide a more comprehensive noise reduction experience. Active noise cancellation primarily targets low-frequency sounds, while the passive component helps block out higher-frequency noises, resulting in a more complete reduction of external distractions.
Passive noise cancellation is a valuable feature for individuals who prefer a more natural and balanced audio experience without relying solely on electronic noise cancellation.
