Things Iโ€™ve learned, published for the public benefit
Hope This Helps header image


One thing I’ve noticed about myself is that I seem to believe that anything can be done well or poorly. As a result of my perfectionism and scientific curiosity, I often spend hours obsessively researching even the most mundane problems that crop up in my life โ€“ which air humidifier to buy? how to build a quiet PC that can run recent games? what mp3 bitrate should I use to compress my music? what could be causing vibrations on the steering wheel of my car?

I construct clever Google queries, read through hundreds of posts, engage in long and painful thought processes, and โ€“ when all else fails โ€“ I actually do something and see what happens. In the end, I usually come up with some sort of useful synthesis.

Since I am unable to break this habit of trying to do things the Proper Way, the least I can do is share the knowledge I’ve accumulated with others. So when I get an interesting result that I have not been able to find on the Internet, I will post it on this blog in the hopes of helping a few hundred other people with similar needs.

About me

My name is Tomasz P. Szynalski. I live in Wroclaw, Poland. I’m writing this blog in English because I want my posts to help the broadest group of people possible and because I want to promote the use of English as the language for the Internet.

I also made:

I occasionally work as a freelance Polish translator. I spend a lot of time thinking philosophically about the world around me.

    Tomasz, you write better English than 99% of the so-called English-speaking population that I’ve encountered in my lifetime. Wow. You must be directly related to Joseph Conrad.

    • Toby

      I agree! This is a REALLY impressive blog. Your English is fantastic, as (on the limited amount of your blog I have read so far) are your analytical skill and ability to sift bullshit from sense in the goldpanning exercise that is surfing the internet. Keep it up!

  • Przemyslaw Moscicki

    Wow – Tomek – your blog has PageRank 5 – a lot of people would kill for it:)

    Congratulations!!!! I envy you:)))

  • Gaetano Marino

    Hello Tomek,
    thank you for the typing program and links. I have shared our pages with ten friends learning English. is a page you will enjoy.
    If the first attempt to open it is unsuccessful, please don’t quit. It is great.
    God bless you.

  • Megha Patel

    Wow, I do the same thing! Except I do not post >.<

    I just started blogging so maybe I might add my experiences. I wanted to thank you for the loads of helpful information you have posted and will be looking forward to your blogs ^^

    And I agree Thomas W, your English is flawless.

    Take care!

  • Bill Smith

    If I searched, I could probably find some English language flaw. But from what I’ve read so far, nothing has stood out! Good job in your English language learning.

  • Charles A. Gorzenski

    Hi Tomek.

    Your Blog helped me out of a gap regarding Volume Shadow Copy.
    My congratulations and thanks a lot.

    Have a great new year 2010 and keep on writing.

    Kind regards – pozdrowienia

  • Roger Pelizzari

    Bravo Tomasz on a fabulous blog.
    I’ve been enjoying your monitor reviews. I was all set to buy a 2209wa and now I’m thinking more towards an LED backlit screen. Do you have experience with those? Are they safe for the eyes or as some claim does the flicker from the Pulse Width Modulation used for dimming cause headaches?

  • Cano

    You are GREAT! Your posts on HTLAL are the cleverest on the site. You provided great advice and were very funny. I laughed so much that I spent a long time finding you. You are an extraordinary writer in English. I am currently trying to learn Polish. It is difficult for me to find a good audiobook in Polish. I saw the, “Proces – Kafka” 12 CD book as you recommended on Amazon. However, I was not sure of how to find the corresponding Polish translation. I searched by publisher to no avail. I am an intermediate level student of Polish. Maybe I could pay you to help me learn Polish? Maybe I could pay you to translate some jokes from English to Polish? Best wishes.

  • andrew

    One of the better, and more honest blogs.

  • William Lindsey

    Great job, all us perfectionists thank you for helping with the never ending search for the superior products and techniques for doing things. Unfortunately, new doesn’t mean better any more. Older products that were stellar, tend to remain “stellar’ for years — like certain Bose speaker-amplifier models. And I have AR2-A speakers from the 1963 vintage that sound better than most sound systems today. I listen to them daily for the last 49 years. That’s value.

  • swimjenswim

    It seems you haven’t learned anything in a year, or perhaps you’re hoarding all of your knowledge these days.

    hi Tomasz
    i need to ask you something about tinnitus. i need to speak with you

  • Icent

    Hi Tomasz,
    I must say to you that words can never and will never be able to tell the thank you I have in my heart to you, you are a wonderful scientiest.
    I have been treating acid reflux for the past 7 months but couldnt find a way round it with all kind of drugs and vitamins, but God used you to finally free me from this horrible stress that almost took my joy from me.
    In one of your blogs, you mentioned flaxseed for gerd and the way you summerised it was amazing, and I tell you as soon as I started taking the flax seed 3 times daily for just 3 days, I have noticed an absolute esophagus pain free life.
    I am so convinced that I have conqured gerd.
    Thanks once again and I believe you are a special gift from God to mankind. Also thanks to your mother for passing this amazing medicinal food for an ailment that is so expensive to cure.

    I teach Highschool Physics in a school in Thailand. I have found your tone generator to be easily the easiest way for students to investigate resonance in pipes and i am using it this week to investigate frequency-dependent inductive and capacitative reactance in circuits. Thank you!

  • Leonardo Sah

    I’ve just read an article you wrote ( but I wasn’t able to leave a comment. So I looked you up online to ensure you’d read this: Those tips will really help me have my students detect unnecessary mistakes they usually make by not paying enough attention to patterns. I always tell them to watch and listen before trying their own sentences, but sometimes they seem to ignore the sample structures and use a lot of imagination combining a few words that wouldn’t make any sense to a native speaker. Well, in other words, thank you for the article!

  • cande

    Tomasz, two things,

    1) Your bit on Tinnitus and the fact that human beings are mostly incapable of hearing complete silence shut down a panic attack I was having because I was noticing my Tinnitus again. Thank you.

    2). I’m a professional academic editor and I just wanted to say, I was BLOWN AWAY to read that English is not your first language.

  • Bo K

    Just want to say a quick THANK YOU for your writings about tinnitus – they have given me a lot of inspiration about how to “fight noise with noise” so to speak. If i ever get anywhere with my own sound experiments, i will surely share them with you for an opinion.

    Thank you, and all the best from Copenhagen to Wroclaw!

  • DreamMaster Pro

    SUGGESTION: In your title above, I feel you should find a word more successful and triumphant than the word “Try”, which is defined as “an attempt or effort to do something”, as in the expression, “Well at least I tried”, which people say when the utterly fail at something.

    At least here, you have not failed at all. The ongoing help you’ve giving others is real and wonderful. For example it enable me to find the source of strange sounds in my equipment, and to design filters needed, speeding my product toward production.

  • Mary

    Tomasz, thank you for blogging about Tinnitus. I was recently diagnosed and it is frustrating and scary to think this problem might never go away. But I am glad to see lots of helpful and upbeat advice from you and others who have struggled with this mysterious health issue. Also, your use of English is excellent! (I’m a Polish-American and I only know a few words and phrases in Polish although my grandparents and parents were fluent in Polish.) Looking forward to more of your blog posts.

    Also I have proven that with conditioning “you can teach an old dog new tricks”

    • Tomasz

      Jon, many thanks for the report. Glad my generator made a difference. What frequency are you using? The information could come in handy ๐Ÿ™‚

      • Jon

        I use the very top tone and vary it around 18500 – 20100 with the arrow keys until he stops his infernal din ! I think he’s now understanding the link.

    Hello, Tomasz..this “app”, is wonderful, it is exactly what I was looking for.
    Thank you so very much for your service.

    Thanks again. Steve Aspen.

  • Kevin

    Hi – your online tone generator is great – is there any way to add a phase changer to it?

  • Martin

    Thank you for this website. I’ve just recently come upon this page and reading has helped me deal with my tinnitus. I worked around aircraft and jet engines for years, always with ear protection, and 5 years later this tinnitus comes up. My doctor has been unhelpful to say the least, so its’ up to me to do the research. Well spoken and written.

  • Tomasz P. Szynalski

    Thanks, but I’m not sure I understand your question.

  • Tomasz P. Szynalski

    Human beings cannot hear tones below 20 Hz.

  • David Temperley

    Tomasz –

    I work with a chamber music group in Rochester, New York, that is performing a piece for string quartet and “sine wave generator”. The sine tone has to shift pitch several times in synchrony with the quartet, so it has to be “performed” live. Your program is perfect, and we would like to use it for the performance!

    I have made a small donation as an expression of our thanks. (I wish we could give you more, but we have a small budget.) All I ask is that you leave the website running until after October 15, when the performance is! ๐Ÿ™‚

    Thank you again!

    David Temperley

    • Tomasz P. Szynalski

      David — That’s very cool, thanks for writing! I don’t suppose there will be a recording of your performance that I could see? And thank you for the donation; I never got a notification; did you make it in your name? Anyway, best of luck with your performance.

    Hi Tomasz,
    You are a good man. Your English is as good as a lot of people who live in English speaking countries. Keep up the good work.

    • Tomasz P. Szynalski

      Hi Athos, sorry you’re having problems donating. I think you should try entering the address associated with your credit card — the address on file with your bank (in whatever country that is). Thanks for trying to donate, anyway!

  • Chris

    Hi, can you please post your Steelcase Leap review? I just read the one on the Gesture from August and it says you planned to post one for the Leap soon. I’m currently deciding between these 2 chairs and your review would be a great help. Thanks.

    • Tomasz P. Szynalski

      I haven’t posted the review because there hasn’t been a lot of interest in my other reviews. If you have any specific questions, feel free to ask. I decided on the Leap after extensively testing both chairs, but YMMV. Try to buy it from a vendor that will let you test and/or return the chair.

  • Chris

    Greetings Thomasz from Nevada, I just wanted to share this video I found which lead me to your site.
    Keep up the great work!!!

  • Chris

    Very cool online tone generator! I just noticed the sine is 1 Hz higher frequency than the triangle wave, I wonder why that is?

  • Geoff

    Your english and work is amazing! I can’t say enough, and I love the tone generator. I was going to make one but I really can’t think of anything yours doesn’t already have ๐Ÿ™‚

    I am similar in research/project craziness so I can appreciate that. It reflects in the great work you do and hopefully people can appreciate it!

    I love languages and your comment about tools you used to learn English interests me. Do you have a good recommendation for Polish? I know, silly question to ask of a native speaker, but I’m always on the look out for great tools to learn new languages!

    Thank you.

    • Tomasz P. Szynalski

      Thanks for your kind words, Geoff! Some of the stuff I wrote at Antimoon applies to learning other languages, including Polish, but if you’re thinking about specific resources for learning Polish, I’m afraid I can’t help you there. I can definitely tell you that finding quality resources for Polish learners will be hard.

  • Frank

    I saw this program online tone generator a few minutes ago and I tell you I like the program and I want to know if you have an offline version of tone generator licences for sale, and if the answer is yes what is the price ? . I usually buy 5 licences for my family’s personal computers. I did not see for sale info. Thanks

  • David Lea

    Dear Tomasz,

    I was very excited to find your Online Tone Generator. I am conducting a class on the relation between music and physics. It is entitled: “An Astronomer, a Quantum Physicist and a Piano Tuner Walked into a Bar…”

    Here is a link to the class description:

    This was to be a great way to demonstrate the interference waves that tuners use to tune pianos. I have found that the little school house where I am doing the classes does not have wifi so I can’t use your cool program by going on-line. Do you have this as an independent application that I could download and open in multiple windows. I use it now in two, three, four and five windows to demonstrate different tuning temperaments. The pure sine wave makes the concepts pop out at you!

    Let me know if you have or know of such an application. My class starts the second week in February and I am very anxious to use this!!

  • Marcelo

    Hello Tomasz,

    It was a pleasure reading your chair reviews – they were detailed, with much research and effort gone into them, and well-written (congrats on your English proficiency!). Like another commenter, I am interested in your thoughts on the leap. If I may ask: if you were given the choice between a herman miller embody for ~$550 or a steelcase leap for ~250, what is your decision?

    Thank you very much.

    • Tomasz P. Szynalski

      Hi Marcelo. Thanks for reading the reviews. For me, the Leap wins hands down. Even if they were the same price, I’d go for the Leap as I believe it is ergonomically superior. The Embody is too unforgiving and too limited in terms of the recline angle. It is better-looking, cooler, and probably better-made than Steelcase chairs. Right now I’m trying to get my second warranty service because my brand-new Leap keeps making loud clicky-clanky noises and the first repair didn’t help.

  • David Lea

    By the way, are you familiar with the Polish-Canadian musicologist & composer, Mieczyslave Kolinski? In 1959 he wrote an article proposing an equal temperament using the perfect fifth as the basis, that is the 7th root of 3/2 rather than the 12th root of 2. It works. I have been tuning that way for about 15 years. Lucas Mason, a tuner, composer and musicologist from New York wrote the definitive book about it, “The New Tuning”. Sounds like it would be right up your alley to look into it!

    Dave Lea

  • Max

    Goodmorning Dr, my friend..

    recently you transformed your tune-generator in something that is on-attack smoother? .. I did not understand why (very bad attack mode for my needs)

    very bad.. if possible, please resume on_down_spacebar sound without smooothing them.

    ps if it will ok again, Iโ€™m going to publish your tonegenerator url in my psychic-doctor studies.. (and $ some)


  • Juan

    I just love the simple and useful tools that you create. Great job. And thanks.

  • Savageagle (Tim)

    Hello Tomasz, your site is a saver. My tone generator took a dump so I have been using your site with levitation experiments. I got the ping pong ball to levitate at 212, 432 and 522-23. The kids love it and this site has been very helpful in the experiments. This was all done at the classroom and as I said, the kids loved it and so did the teacher who thanked me for exposing her to the site and i’m sure she will use it more than I have.
    Thanks a bunch

  • Antonia Hernandez

    I found your blog because I have sudden onset tinnitus (not noise induced). Iโ€™m only 38.
    Your post was very useful – I am wondering if you still have tinnitus?

  • Kevin Shandrew

    Hey I was looking to buy the one, but thereโ€™s no where to click on to look at product info. I took electronics for yrs. not only a tone generator but a frequency finder or set it with your own clock counter… making a clock counter. Is as far as I got just have to figure out resistantace. Maybe a variable resistor. Anyway thanks for your time.

  • Daniel

    I don’t know about anyone else but I would happily pay for your tone generator page in app form. I use it every day and is the best tool I’ve found for my needs and have heard the same from other professionals.

    I understand this is a big ask but if there’s enough interest you could crowdfund the needed money to convert it.

  • Daniel Cronk

    Why not, as I plan to do,simply make 40 hz music…….

    Do metal tunes,or any kind really, and adjust the 38.891 to 40hz as yopur “D”

    Play everything,or a good junk in drop D tuning…there you gO!

  • phuzzyday

    Love the simple and easy tone generator. I tossed you a bit of support. Thank you!

  • Dev

    Poland has some of the smartest people on earth. Amazing country, wonderful people. Any of you guys who have not been to Poland, make it a point to visit at some point in your life, you will fall in love with the country and the people.

    Thanks Tomasz, and I am planning to donate too. Your site is awesome!

  • Brian

    Hello Tomasz,
    I have had Tinnitus on again off again since 1980’s due initially probably due to noise exposure, which has caused defined loss of hearing in one ear, but it has gotten worse over the years and became permanent about 2 years ago, varying in intensity, but very loud even on good days.
    I was thankful to find your tone generator online and have been able to narrow in to my pure tone frequency.
    Interesting observation I’ve made since I am a bit of an audiophile and understand basic sound wave propagation and the electronics used in many sound systems, is that if I play the tone using your generator on my phone, and move the output speaker into just the right position so that the sound is pointed at and transferring through the bone structure under the ear, the tone tends to cancel out my tinnitus fairly effectively providing almost instant unbelievable relief.
    My thought would be that it must be delayed, or therefore slightly or completely out of phase with my natural tinnitus tone, and this changes as I move the phone around. I’ve been wondering if it is possible to have a function in which you could invert the tone wave, or put it 180 deg out of phase so that one could simply transmit that through a Bluetooth earbud ?
    I can use one of those now, with your tone generator on my phone but it does not produce the same effect, I believe, because it isn’t out of phase.
    This would possibly eliminate the balancing act of trying to get it in just the right position, and also, not annoying everyone else around me

    • Tomasz P. Szynalski

      Hi Brian,
      As I’ve said in reply to other similar questions in this comment thread, tinnitus is a neurological phenomenon, and as such, it doesn’t have a phase. You don’t have to take my word for it, though โ€“ you can just try to start the tone at various random times. If tinnitus had a phase, eventually you would hit on a phase difference that would more or less cancel out your tinnitus.

  • Mike

    I find your online tone generator useful but not useful as i can not download a frequency which means i have to return again and again to listen to the same frequency i’m using i’d be more inclined to donate if your online tone generator had a download link.

  • Rachele

    Hi Tomasz!
    I am a middle schooler, who is contributing in the science fair. My topic is all about Chladni Plates, but I was struggling to find data. Then I thought that I could stroke the bow against the plate, use an app to find out how many hertz it was, and double checked with your website.

    Basically, I am going to use the online tone generator in my bibliography, because it really helped! Thanks!

    PS, this was the easiest tone generator that made sense . The other ones are confusing l:

  • Rob Brown

    Hi, this yet another time to pay homage to technology. Its hard to explain in depth why but the fact that a human in Surrey BC Canada can roll over a website and potentially meet a human from Poland who sounds like a guy that would be great to sit down and half a beer. I want to thank you for the frequency generator. I am going to test it out and hope to see even the slightest change. I will let you know. I have one question, ” is it better to try and physically feel the frequencies or is just the sound alone enough to make your cells dance”

    • Tomasz P. Szynalski

      Hi Rob, I’m afraid nobody knows what is the best way to do this, or even if it works on humans. In theory, if you feel the sound in your body, it could stimulate your brain more. But we’re talking about research on mice that were genetically engineered to get something that mimics AD. This is quite different from a human who gets AD without any intervention. I’m no expert by any measure, but I understand dozens of therapies that have worked on fake-AD mice in the past have proven totally useless on humans… Perhaps it’s just much easier to treat AD if you induce it artificially. We’ll know more in 1-2 years.
