Ask Slashdot: Sounds We Don't Hear Any More?

J. L. Tympanum writes: While discussing music with my 24-year old son, the Typewriter Song (Leroy Anderson) came up. Within 10 seconds he had it playing on his laptop, but he didn't really get the joke because he had never seen a typewriter, nor heard the characteristics sounds — the clack of the keys, the end-of-line bell, the zip of the carriage return — that the typewriter makes. What other sounds do we not hear any more? More points for the longer they lasted (typewriters were around for over a century).

    The sound of a teletype machine. I had a model 15 in my bedroom when I was in High School back in the 60s. It was connected to my shortwave ham radio rig. I used it to converse with other hams around the world. I could also tune in on Reuters news and weather bureau reports. Later, I worked as an Engineer at a radio station. A model 15 was how we got our news from the AP wire.

  2. The whine of the flyback transformer by russotto · · Score: 5, Insightful

    I always knew that one day I'd no longer be able to know a CRT was in the room from the high-pitched flyback transformer sound, but I always expected it would be because of my own loss of high-frequency hearing. But the CRT pretty much disappeared before that. Length of time: less than the telephone.

      Good riddance to CRTs. I always hated that sound. Every so often when I go to an office that has an old TV running, ugh. That sound always drove me nuts.
      When composite-input TVs came out my dad would leave the TV on with the cable box and VCR off and I'd ask him why the TV is still on. He'd say "it's not on." It most definitely was and that annoying whine was driving me batty.

      I used to take apart my TVs to put baffling in to cancel out that sound. I am 43 now and I can still hear past 17.5KHz. Why? Because it was drilled into me by my mom to not blast my ears with headphones, and when using power tools I use hearing protection. I have an even greater appreciation for my hearing now because once I got a sinus infection so bad it spread to both ears and I had 95%+ hearing loss for more than three months when my inner and middle ears filled with fluid, and there was so much pressure it perforated my eardrums, so I'm even more strict about hearing protection having experienced near-total deafness for an extended period. Since then certain frequencies cause some pain due to reverberation because those frequencies seem to be amplified to me - it may be due to scar tissue where my ear drums perforated or something, I don't know and haven't bothered to find out.

      But flyback transformer whine? Ugh. Same with PC power supplies that are going bad - they have a very similar high pitch whine. When I go to my old office to maintain the servers for my partners, I need to stay out of the lobby because the power supply whines like mad. No one else in the office can hear it.

      I'm using a CRT monitor right now, a 21" IBM P275 with a Trinitron tube. Right now I'm enjoying near perfect color reproduction, blacks that are actually black, zero input lag, no ghosting, nothing that resembles backlight bleed and no stuck/dead pixels. Haven't noticed flyback whine for years but that's probably down to my age. LCD is still inferior to CRT in many ways and you have to wonder what CRTs we would have today if development had continued. LCD has also taken a step backwards recently with the introduction of LED backlights, they make for thinner panels and lower power consumption but uniformity of many recent panels is really poor.

      Having said that, my CRT will probably have to go this year, most probably late in the spring when the heat the thing generates is no longer welcome. My desk is also sagging from the weight of it sitting there for nine years.

      I'm experiencing the same except for the wider colour gamut, better contrast ratio, and far sharper picture that comes from spending more than $50 on a modern LCD.

      CRTs haven't outperformed common LCDs for about 5-10 years, and even in the early days if you actually bought a proper LCD like an NEC Spectraview you ended up with something that no CRT could match. Go shopping somewhere other than Wallmart when your CRT finally dies and you'll hate yourself for having lived with that garbage so long. Check out some high-end offerings from all those same companies that produced high-end CRTs for colour critical applications back in the day like Eizo, or NEC, (they are still in the business and they are also the source for panels used in medical imaging etc if you like colour accuracy) and don't base your view of technology on what you somewhat throws at you during Black Friday sales.

      I had a high end trinitron screen as well. It was a great screen back in the day but I don't miss it.

    2. Re:Modem connection tones by Tablizer · · Score: 5, Interesting

      At work we once had a bank of modems, and to check which modem went to which phone number (people sometimes switched them without telling us) we would have to call the number on a voice phone across the way and then run over to the modem bank to see which lights were on. Often the modem lights wouldn't stay on long enough from a mere phone call.

      Rather than run fast and risky in a crowded, wiry data center, I discovered that if I whistled certain frequencies mirroring the connect sound, the modem would think I was another modem and spend a longer time trying to connect. Thus, by learning to speak modemese, I could walk instead of run.

      A computer room steward saw me doing this and told his shift buddies about "the crazy lonely guy who flirts with modems". Referring to their squawky sound, somebody joked about modems being consolation partners after I allegedly got dumped by a Dalek. Good Times!

    Guess you don't live in a cold part of the world in the winter, or where it can hit 35C+ in the summer. Around here in Canada, we use 30-50m segments that aren't welded because the tracks shrink and expand so much. Once the temps drop to -20C here, you can lose over an 3cm, and once it gets over 35C with the train's on them they can expand over 10cm causing them to warp off the bed.

    So if I walk outside, the next time a train goes by I can hear it hit every clack clearly. Since it's around -20C right now, I can hear it inside my house about 300m away if I pay attention.

    What the hell is this? This is not news. Just put this crap in the polls, where questions belong.

    There's a lot of unpleasant news which shows up here. One can only take so much
    of that sort of reality in a day's time, before despair sets in. So an enjoyable lighthearted

    Slashdot these days is a far cry from what it used to be.
