An assembly includes a seat 60 having a seat base 64, an occupant sensor positioned in the seat base, said occupant sensor comprising a fluid filled bladder coupled to a pressure sensor, said pressure sensor generating a pressure signal, and an audio system having an electrical output coupled to a speaker, said speaker positioned near the seat, said speaker audibly coupled to the bladder. The assembly includes a compensation circuit (12) for a sensor (22) generating electrical sensor output near a speaker (18) of an audio system (16) that comprises an inverting circuit (26) coupled to the electrical output (16) of the audio system. The inverting circuit (26) generates an inverted electrical signal corresponding to a speaker audio output. A sensor controller (24) coupled to the inverting circuit (26) and the sensor (22) generates a compensated electrical output in response to the electrical sensor output and the inverted electrical signal.
