The Shouter < link to the first part
The big yellow warning sign on the lab entrance states “Ear protection must be worn”. They bought the sign on amazon, but they had a few bob now, no strings attached.
A lack of thinkimentation and a lot of experimentation happened. The power output of The Shouter quickly grew with better materials. A few 1 farad capacitors from the boy-racer scene brought Dermot and Declan closer to their own mortality, but also brought The Shouter to ever higher performance levels.
Dermot went to a science fair once and saw an ‘air cannon’. A bin with a circle cut out at the bottom and an elasticated plastic bag at the top. He saw the performer scienctist invite young ‘uns up onstage and fire air at their parents.
Declan, who knows about sound, listens to Dermot, who has little sense, gush about how exciting it would be to make The Shouter act like an Air cannon.
Surprisingly easily, Declan, who knows about sound, manages to make the driver tube (the coke can looking bit) nested, with a smaller coke can, like the ones pubs charge a fortune for, sitting inside the larger driver. Dermot, who knows a little about a lot, places a number of smaller shouters around the circumference of the central, nested shouters.
Hook up a controller, Dermot, who likes computers, models the new, admittedly scary looking, Shouter, in the open source Godot game engine. By moving the different drivers at slightly different delays, they can make a highly linear smoke ring looking thing travel all the way down the lab.
Declan, who knows about sound, wants to experiment some more. It’s a computer game now, like a brilliant new toy hooked up and ready for action, but what else can it do?
Dermot, who likes to shmoke a bit, blows shmoke into the front of the Shouter “Ha we should rename it the Shmoker” Declan plays with the Xbox controls. ‘Bang’ a square of shmoke rolls down the lab, ‘Boom’ an octagon skews to the left and rattles glasses on the rack.
Rattles glasses? What if…. Schreeeech pull over a rack full of science looking glasses. They came with the lab who cares.
They can smash them all easily, just by turning it up, but Declan, who knows about sound, picks them off, one by one like some gun toting sherrif in the wild west. A sound like scratching your thumb down the low E string on a guitar, a smash of glass giving up all hope.
They have a few bob now, no strings attached, What if…. Laser range finder, exact distance to wall is… 8 meters, resonant frequency would be…. f =c/2L, let’s say air temp is normal, dunno how to account for all the fuckin shmoke in here, 343 meters per, lets call it 21.267hz. Infrasonic eh, well if a pipe organ can do it so can we.
Eyeballs vibrating in their own sockets, plaster shearing off the walls in sheets, Dermot and Declan, swallowing hard to keep their hot chicken wraps down, looking at eachother. Fuck.
