The upper pitch range of the human voice is, on average, about half as high in males as in females. [3] Even after controlling for body height and volume, the male voice remains lower. Charles Darwin suggested that the human voice evolved through intersexual sexual selection, [ 4 ] via female mate choices.
A vocal register is a range of tones in the human voice produced by a particular vibratory pattern of the vocal folds. These registers include modal voice (or normal voice), vocal fry, falsetto, and the whistle register. [1] [2] [3] Registers originate in laryngeal function. They occur because the vocal folds are capable of producing several ...
This chart only displays down to C 0, though some pipe organs, such as the Boardwalk Hall Auditorium Organ, extend down to C −1 (one octave below C 0). Also, the fundamental frequency of the subcontrabass tuba is B ♭ −1 .
Voice classification is a tool for singers, composers, venues, and listeners to categorize vocal properties and to associate roles with voices. While useful, voice classification systems have been used too rigidly, i.e. a house assigning a singer to a specific type and only casting him or her in roles they consider belonging to this category.

The terms sounding range, written range, designated range, duration range and dynamic range have specific meanings.. The sounding range [3] refers to the pitches produced by an instrument, while the written range [3] refers to the compass (span) of notes written in the sheet music, where the part is sometimes transposed for convenience.
In telephony, the usable voice frequency band ranges from approximately 300 to 3400 Hz. [2] It is for this reason that the ultra low frequency band of the electromagnetic spectrum between 300 and 3000 Hz is also referred to as voice frequency, being the electromagnetic energy that represents acoustic energy at baseband.
The fundamental frequency or pitch of the voice is sometimes referred to as F 0, but it is not a formant. Most often the two first formants, F 1 and F 2, are sufficient to identify the vowel. The relationship between the perceived vowel quality and the first two formant frequencies can be appreciated by listening to "artificial vowels" that are ...
The length of the vocal cords affects the pitch of voice, similar to a violin string. Open when breathing and vibrating for speech or singing, the folds are controlled via the recurrent laryngeal branch of the vagus nerve. They are composed of twin infoldings of mucous membrane stretched horizontally, from back to front, across the larynx.
