Does noise cancelling cancel voices?
Noise cancelling technology is primarily designed to reduce or eliminate ambient sounds, such as background noise, humming, or engine sounds. Although it can help reduce the audibility of certain voices or conversations to some extent, it is not specifically designed to cancel out human voices completely.
When sound waves, including human voices, are detected by the microphone built into noise cancelling headphones or earphones, the technology generates an equal but opposite sound wave to cancel out the incoming sound, resulting in a quieter overall experience. However, the effectiveness of noise cancellation against voices may vary depending on the specific device and its capabilities.
It is important to note that noise cancelling technology is more effective at reducing steady, low-frequency sounds rather than sudden or higher-frequency sounds like voices. Therefore, while noise cancelling can make voices less audible, it may not completely eliminate them. Other factors, such as the volume and proximity of the voices, can also play a role in determining how well noise cancelling can reduce their audibility.
To summarize, noise cancelling technology is primarily designed to reduce ambient sounds, including some voices, but it may not fully cancel out all voices, especially if they are sudden or higher-frequency.
What happens when noise cancellation is on?
When noise cancellation is enabled on a device such as a smartphone or headphones, several things happen to enhance the listening experience:
