Abstract

Methods, systems and devices enabling a party to a telephone conversation to identify sounds for active filtering so that the identified sound can be actively filtered and/or amplified. Cell phones are provided with a button that allows users to identify sounds for filtering by pressing the button or virtual key when the sound is heard. Sounds recorded in response to such user inputs are processed to identify filtering criteria, such as frequencies and amplitude. The identified filtering criteria are then used to actively filter or enhance sounds. The methods and systems enable user to identify specific sounds for filtering so only those sounds deemed annoying are suppressed while permitting other sounds (e.g., voice) to be heard.
