how do microphones in a phone not pick up any audio that the speakers put out? if I put a call on speaker mode, how do people on the other end not hear themselves?
In: Technology
I’m a tech support specialist for a major phone company, and I can tell you the phone company uses algorithms in the transport network to combat feedback and reduce outside noise on phone calls. Much of it is done in the network, not by your phone. That said, it’s not perfect, and if you’ve ever sat on a large conference call you know speaker phones do feedback. I hear my own voice echo, I hear everything in the background. The most annoying are people who eat while they’re on the phone and loud mouth breathers
