The short answer
Many sources place the average adult male fundamental frequency around 100–130 Hz. A broader conversational range of roughly 85–155 Hz captures more natural variation across speakers and situations.
These values describe fundamental frequency, or F0. They do not measure resonance, vocal weight, attractiveness or vocal health.
Why averages differ
Studies use different languages, age groups and speaking tasks. Reading a fixed passage can produce a different average from spontaneous conversation or a sustained vowel.
- Age and puberty history
- Language and habitual intonation
- Emotion, loudness and social setting
- Microphone and analysis method
How to compare your result
Use at least three relaxed ten-second samples and compare their medians. A single unusually low or high reading may reflect the sentence, room noise or an unstable sample.
Natural overlap is normal. A result outside a broad average is not evidence that anything is wrong.
