I’ve bought an external webcam (Genius ECAM 8000) with 2 microphones - the results are the same! A lot of self-noise and no cancellation of side noises at all.Ĭonclusion: Two microphones are just two microphones! Even an array with two microphones doesn't give you any kind of noise cancellation at all! There is just more than one microphone, which gives you maybe some stereo effect or some other benefits, I don't know. Maybe an external webcam? They’re made for conferences, isn’t it? So, when I don’t speak, others hear a lot of background noise. I’ve replaced my old laptop with a modern pretty expensive model HP Elitebook in the hope that it has better microphones for such a price.īut the results are the same - a lot of background noise and no cancellation at all.Īnd even more - when I’m not speaking, its microphones thinks that I speak just quietly, and increase their own sensitivity, making all side sound louder. Maybe just the laptop is too cheap? Let’s try a more expensive one? Two mics, it would seem, should cancel side noise well, I thought… But not! All side noises are caught pretty loud, even louder than my ears hear them!Īnd a lot of self background noise, even in a quiet room, and keyboard clicks are too loud… I’ve started with an old good laptop ThinkPad X240, which has a built-in microphone array with two microphones. The problem: The main problem is that most of the microphones pick up all side talk pretty loud, which makes it very unpleasant for other people to listen to my voice in meetings! And the journey… Station 1: Built-in laptops and webcams with microphone array So, silence in the room is a rare situation. The environment: I work in a pretty talky office room, where sit around 10 people, and all of them have many online conferences every day, including me. And physical cancellation is implemented well only in Jabra devices yet, but other features suck them! All Bluetooth headsets suck too! So, no solution yet, just complaints! TL DR: All AI-based noise cancellations suck, only the physical cancellation technique works! It's named " beamforming microphone ".
