<u>Men's voices, when they speak normally, go up to 155Hz, women's up to 255Hz, but children's voices are raging between 250 Hz to 300Hz, or even higher.</u><u> </u>
<u>In most cases, children will have a higher frequency of the voice than any full-grown adult. </u>
It is also noted that even older people, as they age, have notable changes in voice. Adult men that usually have low voice frequency tend to have a higher and higher frequency of the voice as they age. Women go through a different process - they have a high frequency of the voice and during the aging process, it lowers down notably according to studies.
