1. An acoustic dose meter comprising:
a cylindrical housing including a cylindrical seat configured to stage a pressurized medicine canister having a first diameter, the housing having a length and a second diameter and including at least one compartment for housing electronics and passageways for connecting electronics for power and data communication;
a microprocessor including a transient memory containing machine instruction;
a power source connected to the microprocessor;
a power switch connected to the microprocessor and the power source for booting the microprocessor;
at least one visual display device connected to the microprocessor;
a first set of acoustic sensors positioned in a linear array along the length of the housing and connected to the microprocessor and adapted as acoustic sound generators; and
a second set of acoustic sensors positioned in a linear array along the length of the housing and configured to be positioned at an opposing position across the first diameter and are connected to the microprocessor and adapted as acoustic soundwave recorders;
wherein the housing length is greater than a length of the medicine canister and the microprocessor is configured to determine a volume density of medicine in the medicine canister and calculate an amount of remaining doses in the canister based on information received from the second set of acoustic recorders.
