The Shouter (4)

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.

Link to the first in the series here

Fu-kin legends bai. Rumours and stories flit around the school like bats. Parish priest makes an announcement; ‘We are not sure what exactly happened in the local last Friday, but we ask that we, as a…. communitee, do not pass judgment on what looks to be two young lads working hard on the science’.

Barman, half a head of hair and covered in steri-strips, ‘sure lookit, it could put this place on de map!’. A village where everyone plays or listens to music.

A car pulls up the drive, two tweed suits get out, and crunch up to ask mammy where the ‘young fellas’ are. ‘The shed’.

Dermot, Declan, Tweedie Dum, Tweedie De, are a close fit in the shed. ‘Youse boys are running a pirate station, that’s illegal’. Dermot, who reads too much; ‘Akshually, you’re meant to make a citation in pursuance to the Broadcasting act of 2009’. Dead air. Dermot often causes silence, this was nothing new.

‘We’ve ben asked to approach yez around an opportunity’, ‘a certain company has said thy have an empty electronics lab there in city west, no strings attached’. ‘No stings me hole’. Phone number swapped. shoulders shrug and ‘sure why not’. Offer accepted that night.

Declan, who knows about sound, looking forwards to getting his hands on some better equipment. Dermot, who reads a lot; ‘No strings me hole’.

The Shouter – Part 1

The bus, the way home, the ignominy. Two less than happy campers, Dermot and Declan stared glumly into their box of equipment. Their new invention, “The Shouter”, looked like a coke can on it’s side, wrapped in copper wire, sitting inside a poster tube. Maybe they should have painted it to make it look more… well, fancy. That said, haey knew why no one was impressed… they weren’t allowed turn The Shouter up! They couldn’t hear it!

A mind melding, brain scratching session ensued, how to let people hear the shouter. Like, really hear it. Declan, who knows about sound, knows a local band that plays in the local pub every local Friday. Dermot, who didn’t, thinks this is a great idea.

Friday. Pub with about three locals trying to ignore the ‘young lads’ messing around with the ancient PA system. Declan wiring up two prototype ‘Shouters’. Dermot allowed play with the mixing deck trying to see how much power they could feed in. The band tuning on stage, excited. They play this gig for fun, mostly, and free pints. Everyone in this town plays music. Or listens to it.

Declan, who knows about sound, decides to hold the “Shouters” in reserve, and lets the regular sound system work away for a while. Pub fills up, rock music kicks in. Everyone TALKING VERY LOUDLY to hear each-other. Dermot; signals to bassist who signals to drummer. Singer nods and takes a break. Dermot flicks the ‘on’ switch. The lights flicker a bit. Who cares? But, there is a definite hum in the air. Declan, who knows about sound, adds a filter, adjusts some sliders, and the hum gets softer.

Dermot is excited. He has been telling anyone who would listen, and many who didn’t, about The Shouter. Bored them half to death, but the word was out (the three locals who saw the setup, decided at this point, to “maybe head out for a shmoke”, “yep, mbby down the ways a bit”).

The crowd moved up to the stage. The song was ‘Killing in the name of’, it starts with a chwoooongggggg. It would be incorrect to say the place went silent, it was late Friday in a pub, halfway up a mountain in Wicklow. But there was a ceartain palpable potential in the air. The atmosphere was electric. Dermot was a good “hype man”.

The guitarist and bassist both chwoooongggggged.

– White pain then silence. Screams but no sound. Beer, Spirits and glass blizzarding. The pub, a deranged snowglobe shook hard by a giant. People crying, blood in their noses falling and twirling as Beer and Spirits and glass flurried over them.

A beautiful ringing starting to come out of the silence as ears decided it was time to start working again.

Declan, who knew about sound, turned to Dermot, both of them with the biggest grins possible plastered across their faces. It had worked! They had Heard!

The Shouter

‘That’s like a mule kickin ya’. ‘Jasus, its makin me feel sick’.

Dermot and Declan, one time participants in the annual ‘Young scientist competition’ held every year in Dublin, Ireland; unwittingly experimenting on themselves with a new speaker design…

‘You know regular speakers, they use elastic to bounce the cone back and forth’ Dermot wondered one day while not paying attention in Maths class, or was it Physics? ‘What if we, ya know, used a metal cylinder as a driver, and used an electromagnet to drive it in and out of a box’ sketch sketch sketch.

‘It would mean we could make it move very slowly even if it was small’. Declan, who knew about sound, was sceptical to say the least, but, did admit that the requirement of having a larger cone to vibrate more slowly to produce bass notes would not be required if one could maintain control of the objects position exactly; ‘We could even focus the output’.

Experimentation proceeded in the shed out the back of Declan’s house. This also happened to be the home of “Radio Wow”, the dance orientated pirate radio station blasting the airwaves (and many nearby unprotected electrical devices) ‘Wowing you out every Monday to Thursday after homework yowsa‘. While prototyping the new ‘speaker’ (at this point they wanted to call it a ‘Shouter’) with Massive Attack’s ‘Teardrop’; had made themselves feel very uncomfortable- ‘intestines weren’t built for shaking Dermot‘.

Success achieved, the Shouter could achieve any low frequency, and up to ultrasonic. The loudness was a function of how long the central cylinder was, and how much power they put into it.

With four of them stacked in a box, they could also make the sound pulse highly directional, and more importantly, focused.

Cue the event, Dermot and Declan set up their display at the Young Scientists. Sleepless nights proceeded, dreaming of just how impressed everyone would be, not just of the ‘Shouter’ as it was officially named, but also of their amazing choice of music which which they would demo it! Declan, who knew about sound, had worked on the playlist all week. Dermot, had thought just how impressed all the female young scientists might be, and did no work at all.

They were asked to turn it down after approximately 47 seconds.

The organisers were not impressed. Dermot and Declan were not impressed. The ‘growing edible mushrooms on poop’ young scientists from the stand directly across from them were not impressed; they were also quite pungent having gotten quite the fright as ‘Whole lot of Rosie’ by ACDC accidentally focussed on them while they were in the middle of a particularly delicate part of their display setup.

To be continued….. and perhaps edited….
