Tone generator generates a sinusoidal signal on the set frequency. Can by use for test audio equipment, earphones or speakers, as well as learning tool for physics. You can test tablet speakers frequency range too.
- Audio Test Tones are for the the experts among our readers. These tones are best used in conjunction with external devices, such as a sound level meter or an audio spectrum analyzer. These test tones will help you testing your audio equipment, loudspeakers, headphones, and room acoustics.
- For setting the input sensitivity on an amplifier using our 9-step method, a sine wave test tone recorded at 0 dB reference level in the frequency range to be amplified is needed. Select the tone appropriate for your application from the list below to download the track: Sine Wave - 50 Hz; Sine Wave - 200 Hz; Sine Wave - 1 kHz; Sine Wave - 8 kHz.

What can I use this tone generator for?
Tuning instruments, science experiments (what’s the resonant frequency of this wineglass?), testing audio equipment(how low does my subwoofer go?), testing your hearing (what’s the highest frequency you can hear? are there frequenciesyou can hear in only one ear?).
Tinnitus frequency matching.If you have pure-tone tinnitus, this online frequency generator can help you determine its frequency.Knowing your tinnitus frequency can enable you to better target masking sounds and frequency discrimination training.When you find a frequency that seems to match your tinnitus, make sure you check frequenciesone octave higher (frequency × 2) and one octave lower (frequency × ½), as it is easy to confusetones that are one octave apart.
Alzheimer’s disease.There is some early-stage scientific evidence that listening to a 40 Hz tonecan reverse some of the molecular changes in the brains of Alzheimer’s patients. This is one of these things that sound too good to be true,but early results are very promising. Here’s asummary of the research so far and a report from a user whotried 40 Hz therapy on his wife.(Note that this tone generator is not a medical device – I don’t guarantee anything!)
