Abstract
A computing device, such as a headset, provides for selective sound level reduction or sound level amplification for sounds made in a local area. The computing device includes a speaker assembly and a controller. The controller receives an audio signal from a second computing device, such as a second headset, via a wireless connection with the computing device. The audio signal describes a sound made by a user of the second computing device. The audio signal arrives at the computing device prior to the sound. The controller determines an audio filter to selectively adjust an amplitude of the sound and applies the audio filter to the audio signal to generate audio content. The controller presents, via the speaker assembly, the audio content to a user such that the presented audio content combines with the sound to selectively adjust the amplitude of the sound.
