1. An audiometric receiver system comprising:
a transmitter, wherein the transmitter comprises a digital signal processor, and wherein the digital signal processor comprises a quality check component, an amplifier or attenuator component, a mixer component that merges individual audio signals modified by the amplifier or attenuator component into one signal and includes a respective header and footer between each audio signal merged into the one signal, a modulator component, and an encrypter component; and
a receiver, wherein the receiver comprises a decrypter component, a demodulator component, a splitter component that splits the one signal into the individual audio signals based on the respective header and footer between each audio signal in the one signal, and a second amplifier or attenuator component.
