What Is Hz (Hertz)?

Hz Frequency Generator (Free Online Tool + Complete Frequency Guide)

 

Hz (Hertz) is the unit used to measure frequency.

1 Hertz = 1 vibration (cycle) per second.

If a tone is 432 Hz, it means the sound wave vibrates 432 times per second.

Higher Hz = higher pitch
Lower Hz = deeper sound

Examples:

  • 60 Hz – Electrical systems

  • 440 Hz – Standard musical tuning pitch (A4)

  • 432 Hz – Alternative tuning used in meditation music

  • 1000 Hz – Hearing test reference tone

  • 20,000 Hz – Upper limit of human hearing

Understanding frequency is essential in:

  • Music production

  • Sound engineering

  • Meditation & brainwave entrainment

  • Physics experiments

  • Hearing tests


How to Use the Hz Frequency Generator

Using the tool is simple:

Step 1 – Enter Frequency

Type any value in Hz (e.g., 432, 528, 1000).

Step 2 – Select Wave Type

Choose between:

  • Sine wave (pure tone)

  • Square wave (sharp signal)

  • Triangle wave (smooth variation)

  • Sawtooth wave (bright harmonic sound)

Step 3 – Adjust Volume

Set a safe listening level before playback.

Step 4 – Click Play

Instantly generate your custom tone.

For meditation use, headphones are recommended for binaural beat modes.

Understanding waveform types helps you use the generator properly.

Sine Wave

The purest tone. Used in testing and calibration.

Square Wave

Sharp transitions. Used in electronics and signal testing.

Triangle Wave

Smoother than square. Rich in odd harmonics.

Sawtooth Wave

Bright and buzzy. Common in synthesizers.

These waveform options make the tool suitable for both technical and creative users.


Hz Frequency Generator for Meditation & Brainwaves

Hz Frequency Generator (Free Online Tool + Complete Frequency Guide)

Many users search for:

  • 432 Hz generator

  • 528 Hz generator

  • binaural beats frequency generator

  • alpha wave frequency

Brainwave states correspond to certain frequency ranges:

Brainwave Range Mental State
Delta 0.5–4 Hz Deep sleep
Theta 4–8 Hz Deep meditation
Alpha 8–12 Hz Relaxed focus
Beta 12–30 Hz Active thinking
Gamma 30+ Hz High cognition

Binaural beats work by playing slightly different frequencies in each ear, allowing the brain to perceive a third frequency equal to the difference between them.

Note: Scientific evidence on therapeutic claims varies. This tool is for informational and experimental purposes.


Professional Uses of Frequency Generators

Frequently Asked Questions

What Hz frequency is best for meditation?

Common choices are 432 Hz, 528 Hz, and alpha range (8–12 Hz). Preferences vary by individual.

Is 432 Hz better than 440 Hz?

440 Hz is the international tuning standard. 432 Hz is used in alternative tuning systems. Scientific consensus does not confirm superiority.

Can I generate ultrasonic frequencies?

Yes, but humans typically hear only between 20 Hz and 20,000 Hz.

Is this tool free?

Yes. 100% free online frequency generator.

Can I use this for hearing tests?

It can generate test tones, but it is not a certified medical device.


Evidence & Scientific Perspective

Frequency (Hz) is a well-established physical measurement in acoustics and physics.

While standard frequency measurement is scientifically validated, claims regarding “healing frequencies” such as 528 Hz are still debated in peer-reviewed research.
