A communications device, such as a mobile telephone, is configured with an ambient noise compensation signal generator that is connected between a first microphone and a mixer. A second microphone is employed to detect ambient noise. An original output of the first microphone and a compensation signal generated by the ambient noise compensation signal generator are mixed together prior to being passed to a transmitter. A buffer is provided between the microphone and the mixer to help synchronize the timing of the signals to be mixed and an output of the mixer is provided to an antenna."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ambient noise cancellation for voice communication device","description":"A system and method for reducing or entirely canceling background or ambient noise from a voice transmission from a communications device.
