Subverting Etaria's expectations

"Hear me, hear me, everyone, for today the history changes!"

My voice, recorded by the microphone in my hand, turned into a myriad of zeros and ones that then proceeded down the long cord, through the reverse decoding, and then exploded from the massive speakers hidden on the fifth carriage. 

It took an entire carriage's worth of fuel, fuel-based generators, and then, lastly, speaker equipment to turn my serious but silent voice into a wave of sound that nearly shook the world itself. 

My voice turned into a wave of sound strong enough to push against my back, making both me, Fay, and pretty much everyone within Etaria's party stumble a bit. 

It was also at this point when the noise-blockers proved to be a godsend, turning the powerful sound into an annoyance over an actual threat to our hearing. 

'All okay?' I thought, lowering the cube of a microphone and raising my eyes to check on everyone.
