Abstract
Official abstract text for this publication.
Ambient sound is masked by receiving an audio signal, monitoring an acoustic signal that includes components of both the ambient sound the audio signal, determining a sound level sufficient to at least partially mask the ambient sound, and reproducing the received audio signal to produce an output acoustic signal at the determined sound level.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for masking ambient sound, comprising: receiving an audio signal; monitoring an acoustic signal that includes components of both the ambient sound and the audio signal; determining a sound level sufficient to at least partially mask the ambient sound by: passing the monitored acoustic signal through a second band pass filter and a second envelope detector, passing a comparison signal through a first band pass filter and a first envelope detec…
