1. An accessory for a smart device, comprising:
a plurality of transducers, at least one transducer among the plurality of transducers physically located in proximity to each receiver among a plurality of receivers;
an amplifier; and
a controller and memory comprising instructions, which when executed by the controller cause the controller to:
recognize when a signal to noise ratio (SNR) at any receiver among the plurality of receivers is greater than 0 dB and cause the amplifier to increase noisy frequency signals transmitted to any corresponding transducer to cause the SNR, when the noisy frequency signals are converted to sound by the corresponding transducer, at each receiver to be negative; and
prevent audio processing software associated with each receiver among the plurality of receivers from being able to identify and cancel the noisy frequency signals by randomly hopping the noisy frequency signals output to each transducer corresponding to each receiver so as to independently isolate each receiver differently.
