Frequently Asked Questions
Everything you need to know about our online tone generator
What is the frequency range of this online tone generator?
Our tone generator supports frequencies from 1Hz to 20,000Hz (20kHz), covering the full range of human hearing and beyond for professional audio applications.
What waveform types are available?
We offer four standard waveform types: Sine (pure tone), Square (digital/harsh), Sawtooth (bright/buzzy), and Triangle (soft/mellow). Each waveform has different harmonic characteristics suitable for various applications.
Is this Hz generator suitable for professional audio work?
Yes, our frequency generator uses high-quality audio processing with 48kHz sample rates, smooth frequency transitions, and artifact-free generation, making it suitable for professional audio testing and calibration.
Can I use this for hearing tests?
While our tool generates accurate frequencies, it should not replace professional audiometric equipment for medical hearing assessments. However, it can be used for basic hearing range exploration and educational purposes.
Does the tool work on mobile devices?
Yes, our online tone generator is fully responsive and works on smartphones, tablets, and desktop computers. The interface adapts to different screen sizes for optimal usability.
Why can't I hear very low or very high frequencies?
Human hearing typically ranges from 20Hz to 20kHz, and this range decreases with age. Very low frequencies may not be audible through small speakers, and high frequencies above 15-16kHz may not be audible to many adults.
Is there a volume limit for safety?
Yes, we recommend keeping volume at moderate levels to protect your hearing. Start with low volumes and increase gradually. Always use caution when testing audio equipment or conducting hearing tests.
Can I use this tool offline?
The tone generator works entirely in your browser and doesn't require an internet connection once loaded. However, you'll need to be online to initially access the website.
How accurate are the generated frequencies?
Our Hz generator uses precise digital oscillators with 48kHz sample rates for high accuracy. The frequencies are mathematically exact and suitable for professional calibration work.
What's the difference between the waveform types?
Sine waves are pure tones with no harmonics, square waves contain odd harmonics creating a harsh sound, sawtooth waves have all harmonics for a bright buzzy tone, and triangle waves have fewer harmonics for a softer sound.
