Abstract
In example implementations, an apparatus is provided. The apparatus includes a plurality of microphones to record background sounds, a noise cancellation component to generate an inverted signal to negate the background sounds from an output signal, a memory to store sound patterns associated with known events, a speaker to output the output signal, and a processor. The processor is to compare a background sound of the background sounds to sound patterns stored in the memory, detect an event when the background sound matches a sound pattern and is coming from behind a user, and execute a corrective action to the output signal in response to the event being detected and the background sound coming from behind the user.
