I have checked the top 5 links, they are all some kind of audio files. But I don't have the ability to play an audio file. I think I can combine different frequency in one tone. And I can't adjust volume neither.Have a look at these.
400-700 Hz seems to be nice. If you want a little more bite, you can use a sawtooth wave instead of a sine wave.Hi guys
I need to generate a beep sound as a feedback for user when they pressed a button, are there some frequencies that produce a nice beep sound? I am using a piezo.
Thanks guys!
A sine wave is like a ringing bell and it can be annoying. A triangle wave is more pleasant and less piercing. A square wave sounds more like a saxophone. 440Hz is a middle C and pleasant as well. Higher frequency will make it more attention grabbing (up to 3k Hz).400-700 Hz seems to be nice. If you want a little more bite, you can use a sawtooth wave instead of a sine wave.
Just a small correction. But I agree middle C is pleasant. 440Hz was(is?) the tone on your landline phone before you make a call and is an A on the 4th octave on a piano.440Hz is a middle C and pleasant as well.
Good, I knew there was something special about 440Hz, (pitch standard), I just didn't remember which note it was and I didn't have the motiviation to look. Thank you for being both musically interested and technically astute enough to make the correction.Just a small correction. But I agree middle C is pleasant. 440Hz was(is?) the tone on your landline phone before you make a call and is an A on the 4th octave on a piano.

Just a small correction, US and British dial tones are a combination of 440 Hz and 350 Hz.Just a small correction. But I agree middle C is pleasant. 440Hz was(is?) the tone on your landline phone before you make a call and is an A on the 4th octave on a piano.
