Disclosed is a hearing aid system for selectively conditioning audio signals. The system may comprise a processor programmed to: receive a plurality of images captured by a wearable camera, wherein the plurality of images depict objects in an environment of a user; receive audio signals acquired by a wearable microphone, wherein the audio signals are representative of sounds emanating from the objects; analyze the plurality of images to identify at least one sound-emanating object in the environment of the user; retrieve, from a database, information about the at least one identified sound-emanating object; causing, based on the retrieved information, selective conditioning of at least one audio signal received by the wearable microphone from a region associated with the at least one sound-emanating object; and cause transmission of the at least one conditioned audio signal to a hearing interface device configured to provide sounds to an ear of the user.
