π§ What Is a Frequency Generator?
A frequency generator is a tool that produces sound waves at specific frequencies measured in Hertz (Hz).
1 Hz = 1 vibration per second.
1,000 Hz = 1,000 vibrations per second.
Humans typically hear between:
20 Hz to 20,000 Hz.
Online frequency generators are used in:
Audio engineering
Sound design
Hearing science
Electronics testing
Educational physics labs
Meditation and relaxation
Medihertz Studio functions as a real-time digital signal generator inside your browser.
π What Is Hertz (Hz)?
Hertz (Hz) is the unit used to measure frequency.
Lower Hz = deeper sound (bass)
Higher Hz = sharper sound (treble)
Examples:
20 Hz β Deep subwoofer bass
440 Hz β Standard musical A note
10,000 Hz β High pitch tone
Understanding Hz helps in:
Audio calibration
Hearing analysis
Sound design
Technical signal testing
π Speaker & Subwoofer Testing Guide
You can use Medihertz Studio to:
Detect rattling speakers
Identify distortion
Test bass response
Find frequency dead zones
Check headphone balance
Start at low volume.
Gradually increase frequency.
Never begin at maximum volume.
π§ Meditation & Brainwave Use
Some users experiment with specific tones for:
Focus sessions
Sleep sound layering
Ambient background tones
Sound therapy experiments
You can combine frequencies manually or use headphones for controlled listening.
Always use safe listening levels.
π‘ Safe Listening Guidelines
Important:
Do not use high volume levels
Avoid extended listening at high frequencies

βοΈ Advanced Technical Explanation (For Engineers & Developers)
1οΈβ£ Sine Wave Generation Formula
A pure tone at frequency f Hz is defined as:
x(t) = A Β· sin(2Οft)
Where:
A = amplitude
f = frequency (Hz)
t = time (seconds)
In JavaScript (Web Audio API), this is implemented using an OscillatorNode.
2οΈβ£ Nyquist Theorem
To generate a frequency accurately, the sampling rate must be at least:
2 Γ frequency
Example:
To generate 20,000 Hz safely, sample rate must be β₯ 40,000 Hz.
Most browsers use 44,100 Hz or 48,000 Hz.
3οΈβ£ Binaural Beat Formula
If:
Left ear = 200 Hz
Right ear = 210 Hz
Brain perceives = 10 Hz difference
Beat frequency = |f2 β f1|
4οΈβ£ Digital Audio Considerations
Bit depth
Clipping
Harmonic distortion
Browser audio context latency
