What Is Hz (Hertz)?

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.

Types of Sound Waves Explained

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

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

This tool can be used for:

Audio & Speaker Testing

Check distortion and clarity across frequencies.

Hearing Tests

Generate reference tones like 1000 Hz.

Music Production

Tune instruments (440 Hz standard).

Physics & Acoustic Experiments

Demonstrate wave behavior and frequency principles.

Electrical & Signal Testing

Generate square waves for system testing.

Safety & Hearing Protection

Listening to high frequencies at high volume can damage hearing.

Follow these guidelines:

Keep volume low when testing new frequencies.
Avoid prolonged exposure above 85 dB.
Stop immediately if discomfort occurs.
Ultrasonic frequencies may not be audible but can still affect equipment.

This tool does not replace medical hearing equipment.

Why This Hz Frequency Generator Is Different

Unlike basic tone generators, this tool offers:

Precision Hz control
Multiple waveform selection
Binaural beat options
Solfeggio preset access
Clean, distraction-free interface
Mobile optimization

It works instantly without plugins.

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.
