This test measures your voice frequency in hertz (Hz) — the scientific unit musicians and voice researchers use to describe pitch. Sing or speak into your microphone and the tool detects your fundamental frequency in real time, showing both the Hz value and the corresponding musical note.

What Is Voice Frequency?
Voice frequency is the number of times your vocal folds vibrate per second, measured in hertz (Hz). One hertz equals one vibration per second.
When you speak at a low pitch, your vocal folds vibrate slowly — around 80 to 120 Hz for adult men, 165 to 250 Hz for adult women. When you sing higher, they vibrate faster: a soprano hitting C6 produces roughly 1,047 vibrations per second. The frequency you produce is what people perceive as the “pitch” of your voice.
A few reference points:
- 27.5 Hz — A0, the lowest note on a piano
- 110 Hz — A2, average male speaking pitch
- 220 Hz — A3, average female speaking pitch
- 440 Hz — A4, the international tuning reference
- 880 Hz — A5, soprano singing range
- 1,760 Hz — A6, soprano whistle register
The voice frequency the test detects is your fundamental frequency (f0) — the lowest, strongest frequency in the sound. Your voice also contains higher overtones (harmonics), but the fundamental is what defines the perceived pitch.
How to Use the Voice Frequency Test
- Allow microphone access in your browser
- Speak or sing in your natural voice
- The tool displays your frequency in Hz and the matching musical note
- Try sustained notes for the most accurate reading — quick speech bounces between frequencies
For singing measurements, sustain a single vowel (“Ahhh”) for at least 2 seconds. For your normal speaking frequency, read a short paragraph and watch the average. Background noise affects accuracy, so use a quiet room.
Voice Frequency Ranges by Voice Type
Speaking voice frequency reference
| Voice Type | Typical Speaking Range |
|---|---|
| Bass (male) | 80–110 Hz |
| Baritone (male) | 100–140 Hz |
| Tenor (male) | 130–170 Hz |
| Contralto (female) | 165–220 Hz |
| Mezzo-soprano (female) | 175–250 Hz |
| Soprano (female) | 220–320 Hz |
| Child (pre-pubertal) | 250–400 Hz |
Singing voice frequency reference
| Voice Type | Singing Range (Approximate) |
|---|---|
| Bass | 82 Hz (E2) – 330 Hz (E4) |
| Baritone | 110 Hz (A2) – 440 Hz (A4) |
| Tenor | 131 Hz (C3) – 523 Hz (C5) |
| Contralto | 175 Hz (F3) – 698 Hz (F5) |
| Mezzo-soprano | 196 Hz (G3) – 880 Hz (A5) |
| Soprano | 262 Hz (C4) – 1047 Hz (C6) |
These are approximate ranges. Your individual range will fall somewhere within or just outside these bands. To pinpoint your exact range, take the vocal range test — it measures your lowest and highest singable notes precisely.
Why Voice Frequency Matters
Frequency is the most precise way to describe pitch. Musical note names like “C4” or “A3” are useful shorthand, but each note corresponds to an exact frequency (or a small range of frequencies under different tuning systems).
Voice researchers, speech therapists, and audio engineers all work in Hz because:
- Universal language — Hz is the same in every musical tradition, while note names vary
- Precision — you can describe pitch differences smaller than a semitone (cents)
- Continuous — frequency is a continuous scale, while notes are discrete
- Equipment compatibility — every tuner, microphone, and audio app reads in Hz
If you’ve ever seen the abbreviation “A=440 Hz” on sheet music or a tuner, that’s the standard concert pitch — the frequency that A above middle C should produce in modern tuning. Some baroque and classical performances use A=415 Hz; some experimental music uses A=432 Hz.
Converting Hz to Musical Notes
The relationship between frequency and notes follows a logarithmic scale: doubling the frequency raises the pitch by one octave. So if A4 is 440 Hz, A5 is 880 Hz, and A6 is 1,760 Hz.
Between each pair of octaves, there are 12 semitones (notes). The frequency ratio between adjacent semitones is the twelfth root of 2 (about 1.0595).
Reference frequencies for one full octave starting at A4:
| Note | Frequency |
|---|---|
| A4 | 440.00 Hz |
| A♯4 / B♭4 | 466.16 Hz |
| B4 | 493.88 Hz |
| C5 | 523.25 Hz |
| C♯5 / D♭5 | 554.37 Hz |
| D5 | 587.33 Hz |
| D♯5 / E♭5 | 622.25 Hz |
| E5 | 659.26 Hz |
| F5 | 698.46 Hz |
| F♯5 / G♭5 | 739.99 Hz |
| G5 | 783.99 Hz |
| G♯5 / A♭5 | 830.61 Hz |
| A5 | 880.00 Hz |

Frequently Asked Questions
What is the average voice frequency? The average adult male speaks around 110 Hz; the average adult female speaks around 220 Hz. Singing frequencies extend roughly 1.5 to 2 octaves above and below speaking pitch.
How do I find my voice frequency? Use this voice frequency test — it detects your fundamental frequency in real time. Speak or sing into your microphone and the tool shows your Hz value plus the matching musical note.
What is the highest human voice frequency ever recorded? The highest note documented in a controlled setting is around 25 kHz — far above the singing range and almost into ultrasonic territory. The highest musical note in commercial recording is generally cited as G10 (around 25,088 Hz), reached by Georgia Brown in a Guinness-listed performance. Standard soprano range tops out around 1,000 to 1,500 Hz.
What is the lowest human voice frequency? Tim Storms, an American singer, holds the Guinness record for the lowest note produced by a human at 0.189 Hz — below the range of human hearing. Normal bass singers operate down to about 82 Hz (E2).
Why does my voice frequency change throughout the day? Speaking pitch typically rises slightly as the day goes on due to vocal fold fatigue and tension. It also varies with emotion, hydration, and overall energy. Variations of 10 to 30 Hz across the day are normal.
Is voice frequency the same as pitch? Practically yes, but technically pitch is the perception of frequency. Frequency is the measured physical property; pitch is how your ear and brain interpret it. The two are very closely correlated.
