Unfortunately, capturing background sounds accurately enough to provide the maximum amount of noise reduction is challenging for dual-microphone setups. While active noise-cancelling microphones can minimize background noise, they also need to be able to reject noise from microphone arrays so users sound good to whoever they are talking to (whether on the phone or talking to a voice assistant). Worse yet, none of us wants to be the person in this situation who is yelling into their phone in an attempt to be heard. Let’s face it, we’ve all experienced making a phone call from a noisy street, busy restaurant or crowded public space in which the symphony of background noises can make it impossible to hear an incoming call.

the system that’s picking up your microphone would block that noise from being transmitted to listeners on the other end?Įnter ANC at the mic, or multi-microphone noise cancellation.

the audio device you’re using to listen through would prevent that loud noise from reaching your eardrums?.

Imagine you’re on a conference call (who among us isn’t well versed in Zoom or another video conferencing solution by now?), and there’s a loud noise in the background of your work environment - say a dog barking or a washing machine buzzing. Noise-Cancelling Headphones and Earbuds: Now A Remote Work Staple This post will highlight another kind of active noise cancellation (although it doesn’t usually go by that name) that works to prevent undesirable sounds from getting into a voice signal.Īs a leader in audio, video and IoT design engineering for voice-enabled products, as a DSP engineering firm, Cardinal Peak employs an experienced team of engineers that excels at adding high-quality voice control to any product, as well as developing products that require ANC, whether at the microphone or in headphone applications. In our recent What is ANC Technology & How Does it Work? blog post, we delved into how ANC technology works and the three basic types of active noise cancellation (ANC).
