The Secret Life of Tone Generator Software

Tone generators have a variety of uses: for testing audio acoustics, creating phone rings or pulsed tones, or testing audio equipment. That’s all good and useful, but check out these alternative uses for NCH's Tone Generator we’ve stirred up.

Note: please consult your doctor before attempting any therapies on your own. We cannot vouch for the validity of any of the following claims.

Sound Therapy
Perhaps the most intriguing application of sound frequencies is in sound therapy. Health problems ranging from cancer to asthma, allergies to influenza can reportedly all be treated with sound therapy. The frequencies can be delivered by radio radiation, plasma, or in Tone Generator's case, audio waves. Because every living thing can be positively or negatively affected by frequencies, there are two ways the treatment can work: either by affecting the offending agent to a point of destruction or inactivity, or by exciting the body’s response to the disease or ailment.

Other uses for sound therapy abound. The frequencies can help in overcoming insomnia, heightening concentration (I’m testing that frequency right now), or calming a person to a state of relaxation. One of the more interesting experiments I read involved lucid dreaming, or the ability to recognize a dream and then control the dream without waking up. I’ve always wanted to have a conversation with Virginia Woolf…maybe I’ll see if Tone Generator can arrange a dream-induced meeting.

I shudder when I recall the sound of mosquitoes whizzing by my ear, warning me of the itch-fest to come. But when I think of tricking them into buzzing off, everything seems right with the world.

It’s a little early in the season yet to try this trick out on those little winged pests, but be certain that I’ll try the moment they start lurking around. Apparently, all you have to do is broadcast a pitch set at the frequency dragonflies buzz about, and the mosquitoes will keep their distance. Since I’ve already tried rubbing down with dryer sheets (didn’t work), citronella candles around the yard (which works if don't you stray too far), and rubbing garlic and onion on my skin (actually, I didn't try because even I wouldn't want to be around myself)—what do I have to lose? I’ll keep you posted on this summer’s battle with the skeeters.

Dog Trainer
We all know that dogs react to high-pitched sounds beyond the scope of human hearing, why not use it as a way to train them? If you can find a frequency your dog reacts to, you can use the sound to get your dog’s attention while you work on their skills.

Or, if your neighbor’s dog has a pesky habit of waking you early in the morning with yapping, you can do the whole block a favor by directing some high pitched frequencies in their direction. Just enough to stop them barking could eventually train them to stop.

So there you have it: the secret life of Tone Generator unveiled. Who knew audio waves could acheive so much? We’d love to hear if there are more, so give us a buzz if you know any other alternative uses for tone generators!


  1. Wonderful article featured in the October 10 Holistic Health Blog Carnival at

  2. Well, at the local volunteer television station, we use this software on a daily basis. Let's explain shortly: every weekday, there is a live broadcast from the town hall. We switch between our broadcast computer and our fibre optic decoder, receiving the signal from the town hall, with a phone switch, reacting to DTMF codes (the tones you hear if you punch a button on your phone).
    Now, we can call in using a laptop with a phone socket. We simply created the tones with Tone Generator and saved these as MP3-files on the hard drive. We call in and play the MP3, and it works wonderfully. Easier than having to remember two 8-digit codes out of your head :)

  3. Interesting post. I actually tried an application on my Droid, also promising to produce high-pitched sound for dogs, but they don't know it... I'll give this one a try, it would be very helpful. Thanks! :)
