The discussion centers on the concept of human frequency, specifically the frequencies associated with human speech and hearing. It is established that the primary energy of human speech occurs between 300-500 Hz, with maximum energy at 250 Hz and 500 Hz, which correspond to vowel sounds. The overall human hearing range is recognized as 20 Hz to 20,000 Hz, although this can vary among individuals. Additionally, the frequency of the entire human body is noted to be approximately 10 Hz.

trupha said:when I comes to human frequency..then whch frequency so people really mean..i couldn't be clear about it..i heard people associating numbers 500hz as the frequency at which we talk,20-20000 hz as the freuncy of humans...thus I`m unable to become clear in what I`m asking..so please help me with this..
Average long term speech spectrum (talking over one minute). The maximum energy is in the 250Hz and the 500Hz band. These lower-frequency bands correspond to vowel sounds, the higher-frequency bands in the 2k and 4k region correspond to consonant sounds.
Hearing range usually describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels. The human range is commonly given as 20 to 20,000 Hz, though there is considerable variation between individuals, especially at high frequencies, and a gradual decline with age is considered normal.
