check it with Ba-a-a-a-a-ahââ with the âahâ going on and on like an all-clear signal. âThat bother you?â called Zeitgeist over the noise.
âItâs awful!â shouted Joe. This time he did cover his ears. It didnât help. Zeitgeist switched off the noise and laughed at him. âThatâs understandable. Your own voice, and it goes on and on like that. Whatâs bothering you is, it doesnât breathe. I swear you could choke a man half to death, just by making him listen to that. Well, donât let it worry you. That thing over thereââhe pointed to a massive cabinet against the wallââis my analyzer. It breaks up your voice into all the tones and overtones it contains, finds out the energy level of each, and shoots the information to that tone-generator yonder. The generator reproduces each component exactly as received, through seventy-two band-pass filters two hundred cycles apart. All of which means that when I tell it to, it picks out a single vowel soundâin this case your âaâ in âBarnesââand hangs it up there on the âscope like a photograph for as long as I want to look at it.â
âAll that, to do what I do when I say âah?â â
âAll that,â beamed Zeitgeist. Joe could see he was unashamedly proud of his equipment. He leaned forward and flicked Joe across the Adamâs apple. âThatâs a hell of a compact little machine, that pharynx of yours. Just look at that wave-form.â
Joe looked at the screen. âSome mess.â
âA little tomato sauce and you could serve it in an Italian restaurant,â said Zeitgeist. âNow letâs take it apart.â
From another bench he carried the cable of a large control box, and plugged it into the analyzer with a many-pronged jack. The box had on it nearly a hundred keys. He fingered a control at the end of each row and the oscilloscope subsided to its single straight line. âEach one of these keys controls one of those narrow two-hundred-cycle bands I was talking about,â he told Joe. âYour voiceâeverybodyâs voiceâhas high and low overtones, some loud, some soft. Hereâs one at the top, one in the middle, one at the bottom.â He pressed three widely separated keys. The speaker uttered a faint breathy note, than a flat tone, the same in pitch but totally different in quality; it was a little like hearing the same note played first on a piccolo and then on a viola. The third key produced only a murmuring hiss, hardly louder that the noise of the amplifier itself. With each note, the âscope showed a single wavy line. With the high it was a steep but even squiggle. In the middle it was a series of shallow waves like a childâs drawing of an ocean. Down at the bottom it just shook itself and lay there.
âJust what I thought. Iâm not saying youâre a soprano, Joe, but thereâs five times more energy in your high register than there is at the bottom. Ever hear the way a kidâs voice climbs the scale when heâs upsetâwhining, crying, demanding? âSpose I told you that all the protest against life that youâre afraid to express in anger, is showing up here?â He slid his fingers across the entire upper register, and the speaker blasted. âListen to that, the poor little feller.â
In abysmal self-hatred, Joe felt the sting of tears. âCut it out,â he blurted.
âCaht eet ow-oot,â mimicked Zeitgeist. Joe thought heâd kill him, then and there, but couldnât because he found himself laughing. Theimitation was very good. âYou know, Joe, the one thing you kept droning on about in the other room was something about âthey wonât listen to me. Nobody will listen.â How many times, say, in the office, have you had a really solid idea and kept it to yourself because ânobody will listen?â
