ABOUT 1 KHZ
A simple reference frequency
1 kHz means 1,000 hertz, or 1,000 complete cycles of a periodic waveform per second. It is a commonly used reference frequency in audio applications.
A sine wave at 1 kHz provides a simple, steady signal that can be useful when checking basic audio playback, comparing equipment or testing an audio path.
PRACTICAL USE
Using a 1 kHz tone for audio testing
Compare playback
Use the same reference tone when comparing different playback setups under similar conditions.
Test an audio path
A steady reference signal can help identify whether an audio path is passing sound normally.
FAQ
Frequently asked questions
What is a 1 kHz tone?
A 1 kHz tone is a sound wave with a frequency of 1,000 cycles per second. It is commonly used as a reference signal in audio testing and measurement.
Why is 1 kHz commonly used for audio testing?
1 kHz sits in the middle of the commonly discussed audible frequency range and is easy to generate and measure, making it useful as a reference signal.
Can I generate a 1 kHz tone online?
Yes. This page generates a 1 kHz tone directly in your browser using the Web Audio API. The generator opens with 1 kHz already selected.
Is 1 kHz the same as 1000 Hz?
Yes. 1 kHz means one kilohertz, which equals 1,000 hertz or 1,000 cycles per second.
What volume should I use for a 1 kHz test tone?
Start at a low volume and increase it only when necessary. A continuous test tone does not need to be played loudly.
