Claim:
1. A system for controlling equipment in a wellbore using infrasonic waves, the system comprising: an infrasound generator positioned at the top of the wellbore, the infrasound generator including a resonator and an actuator for producing infrasound waves, the infrasound generator for directing the infrasound waves down the wellbore, wherein the wellbore functions acoustically as a waveguide; and a receiver attached to downhole equipment in the wellbore for receiving the infrasound waves and, based on the frequency of the infrasound waves, communicating commands to the downhole equipment, wherein the equipment in the wellbore comprises an inflow valve configured to regulate production flow; and machinery above the infrasound generator, wherein the infrasound generator has a resonator and an actuator, wherein the actuator channels white noise from the machinery and the resonator filters out noise other than the frequency required to control the downhole equipment.
