1. A communication system, comprising:

  • a plurality of transceiving devices including at least a first transceiving device and a second transceiving device, each of the plurality of transceiving devices comprising;

    a voice transmitting module having a microphone and configured to transmit signals to other transceiving devices in the communication system; and

    a voice receiving module having a speaker and configured to receive signals from the other transceiving devices in the communication system, the speaker being configured to provide an audio output;

    wherein at least the second transceiving device comprises a regulator module, the regulator module being configured to modulate first signals provided by the voice transmitting module of at least the first transceiving device and provide second signals to the voice receiving module of the second transceiving device, the second signals being modulated relative to the first signals based on a distance between the first and second transceiving devices;

    wherein a volume of the audio output generated by the speaker of the second transceiving device decreases according to a first mathematical function up to a threshold distance between the first and second transceiving devices; and

    wherein the volume of the audio output generated by the speaker of the second transceiving device decreases according to a second mathematical function for at least some distances between the first and the second transceiving devices that are greater than the threshold distance.
