ENC Vs ANC – Key Differences
1. Microphone Array
Both ENC (Environmental Noise Cancellation) and ANC (Active Noise Cancellation) technologies utilize microphone array for effective noise control. However, the difference lies in their approach towards the microphone array. In ENC, the microphone array is used to capture the external noise and then subtract it from the original sound to provide noise-free sound output. On the other hand, ANC also uses a microphone array to capture the external noise, but it cancels it out by producing an equal and opposite sound wave.
2. Real-Time Processing
Real-time processing is crucial in both ENC and ANC technologies as they need to constantly analyze the external sound to produce a noise-free output. When it comes to real-time processing, ENC performs better as it does not require powerful processing capabilities. This means it consumes less battery, which is a significant advantage for mobile devices. ANC, however, requires a powerful processing unit to analyze and cancel out external noise in real-time.
3. Voice Enhancement
Both ENC and ANC technologies work towards enhancing the voice and reducing the ambient noise. Nevertheless, the approach used by ENC differs from ANC. ENC relies on capturing the ambient noise and removes it by subtracting from the voice input. Whereas ANC cancels out the ambient noise by producing an equal and opposite sound wave. ANC not only enhances the voice but also eliminates the ambient noise to provide a better audio experience.
4. Dynamic Adaptation
Dynamic adaptation is a crucial feature as the external noise can vary and change within a second. While both ENC and ANC have dynamic adaptation features, ANC is better in adapting to a changing environment due to its powerful processing capability. ANC is more effective in reducing ambient noise in environments such as airplanes, construction sites, and busy streets, while ENC performs better in less dynamic environments.
5. Immersive Audio
Environmental Noise Cancellation (ENC) and Active Noise Cancellation (ANC) are two competing technologies that vie for delivering a truly immersive audio experience. Both have their own sets of advantages and limitations. While ANC aims to cancel out all background noises, ENC is more selective in blocking only specific ranges of frequencies. ANC is more effective in reducing low-frequency sounds, while ENC is better at isolating high-frequency sounds. This makes ANC the better choice for airplane engines and traffic noise, while ENC may be more suitable for office chatter or the sound of clanging dishes in the kitchen. Depending on the user’s requirement, the choice of technology may differ.
6. Customizable Settings
Both ENC and ANC offer customizable settings that allow users to personalize the sound experience as per their preferences. However, ANC provides more flexibility in terms of the level of noise-cancellation that can be adjusted as per the environment. ENC usually has pre-set modes that can be switched on or off but with limited options for customization. ANC, on the other hand, offers different levels of noise-cancellation that can be controlled through settings on the device or the accompanying app. The user can choose from a scale of 1-10, with 1 being the lowest and 10 being the highest level of noise-cancellation.
7. Long Battery Life
When it comes to battery life, ENC tends to outperform ANC. As ENC uses less power to cancel out only specific frequencies, it can provide up to 50% more battery life than ANC. On average, ANC headphones offer around 20-30 hours of battery life, while ENC headphones can last up to 45 hours on a single charge. This makes ENC the preferred choice for users who require their headphones to last longer without regular charging.
8. Use Cases
ENC and ANC have their use cases based on the environment, and they perform differently in different situations. ANC is more effective in loud environments like plane cabins, train stations, and cafes that have a constant hum. ENC, on the other hand, is better-suited to quieter spots, such as libraries or home offices, where you may need to cancel out only specific sounds. Additionally, ANC is more efficient at cancelling out low-frequency noise like airplane engines, while ENC can work well against background noise or high-frequency sounds. Thus, choosing between them depends on the user’s needs, the environment they are in, and the level of customization they require.
9. Device Compatibility
When it comes to device compatibility, both ENC (Environmental Noise Cancelling) and ANC (Active Noise Cancelling) have their own strengths and weaknesses.

ENC uses multiple microphones to analyze the sound and create an opposing sound wave that cancels out the noise. This means that it’s particularly effective at reducing low-frequency background noise, such as the hum of an airplane engine. In contrast, ANC works by creating a sound wave that matches the frequency of the background noise and canceling it out. This makes it more effective at reducing constant, high-frequency noise such as the sound of a fan or white noise.
12. Application Range
ENC and ANC have different application ranges depending on the type of noise you want to reduce. ENC is particularly useful for reducing low-frequency background noise, making it a great choice for traveling on airplanes, trains, or buses. It can also help reduce noise in noisy environments such as cafes or open-plan offices. On the other hand, ANC technology is better suited for reducing constant, high-frequency noise, making it ideal for reducing the sound of fans, wind, or white noise. ANC can also be particularly useful for blocking out noise when you’re trying to focus or sleep.
13. Complexity
When it comes to complexity, ENC and ANC take very different approaches. ENC technology is generally considered to be more complex due to the multiple microphones required to analyze the sound and create an opposing sound wave. ANC, on the other hand, is simpler in design, as it only requires a single microphone to work. However, this doesn’t mean ANC is necessarily less effective. In fact, the simplicity of the technology means it can be more portable and easier to incorporate into different types of earbuds and headphones. Additionally, some ANC products may feature more complex algorithms or software to enhance their performance.
