Audible noise emitted by devices included in computer systems is pre-characterized by producing a noise profile from a representative device. The noise profile includes information which is related to the sound emissions of the representative device. The profile can include information relative to fundamental and harmonic components of the representative device. The noise profiles are stored in a storage device which are accessible to the computer system. The computer system is monitored for certain system status and events and when specific events are detected an appropriate noise profile is selected. In certain embodiments, representative fundamental frequency profile information is replaced with actual operational frequency information. The selected noise profile is then used to generate a noise shaping audio signal which: removes the harshness of an edgy sound, alters the pitch, removes pure tones, suppresses and/or otherwise masks the sounds emitted by the devices.
