1. A dispensing system, comprising:

  • a conduit including a valve stem of an aerosol container and a volumetric capacity between an internal discharge orifice for receipt of a flow of pressurized fluid from the valve stem and an external discharge orifice;

    a volume of pressurized fluid; and

    a sensor,wherein the fluid has a volumetric flow rate of about 0.05 ml/ms to about 15 ml/ms when released into the volumetric capacity from the internal discharge orifice,wherein the sensor detects a sound at the external discharge orifice,wherein the sensor detects a level of the sound that corresponds to different flow rates, andwherein a ratio of a threshold level of sound to the detected level of sound during an actuation state is less than one at a first stage and substantially unity at a second stage.
