![]() ![]() The mobile phone calling experience was quite bad 10 years ago. Once captured, the device filters the noise out and sends the result to the other end of the call. This seems like an intuitive approach since it’s the edge device that captures the user’s voice in the first place. Traditional noise suppression has been effectively implemented on the edge device - phones, laptops, conferencing systems, etc. Traditional Approach to Noise Suppression This post focuses on Noise Suppression, not Active Noise Cancellation. Active noise cancellation typically requires multi-microphone headphones (such as Bose QuiteComfort), as you can see in figure 2. This contrasts with Active Noise Cancellation (ANC), which refers to suppressing unwanted noise coming to your ears from the surrounding environment. Noise Suppression filters it out for both callers. Noise suppression in this article means suppressing the noise that goes from your background to the person you are having a call with, and the noise coming from their background to you, as figure 1 shows. Current State of Art in Noise Suppression Let’s take a look at what makes noise suppression so difficult, what it takes to build real time low-latency noise suppression systems, and how deep learning helped us boost the quality to a new level. Since then, this problem has become our obsession. Two years ago, we sat down and decided to build a technology which will completely mute the background noise in human-to-human communications, making it more pleasant and intelligible. ![]() Let’s hear what good noise reduction delivers. This vision represents our passion at 2Hz. Now imagine that when you take the call and speak, the noise magically disappears and all anyone can hear on the other end is your voice. It’s just part of modern business.īackground noise is everywhere. We all have been in this awkward, non-ideal situation. You have to take the call and you want to sound clear. Tons of background noise clutters up the soundscape around you - background chatter, airplanes taking off, maybe a flight announcement. Suddenly, an important business call with a high profile customer lights up your phone. ![]() Imagine waiting for your flight at the airport. ![]()
