A sound is a vibrational kind of energy which travels via air or any other medium. Vibration is defined as a rapid to-and-fro or up-and-down movement around a mean position. Vibrations travel through a medium like air to our ears, in which the brain converts them to sound. Humans can make a sound which starts in the larynx or voice box, that is located in the neck. The sound generated is controlled by vocal cords, that are little membrane structures which run across the larynx. The vibrating body can be made of stretched animal hide (as in drums and tables), stretched strings (as in guitar and sitar), or air columns (as in flutes and pipes).
Sound Produced By Humans
Humans use the speech box, generally referred as the larynx, to produce sound. In our neck, the voice box is placed at the apex of the windpipe. In the human voice box, the vocal cords are two ligaments. Sound is produced by the waves of the vocal cords. The muscles which control the stress and stretching of the vocal cords, and also the space between them, are connected to the vocal cords. The muscles of the vocal cords are completely relaxed, enabling them to divide and release, allowing air from the lungs to flow into them silently.
The two vocal cords are divided by a large distance while we are not speaking or singing. The muscles in our vocal cords contract if we wish to speak, stretching and shutting the two vocal cords together, leaving only a little slit between them. The lungs transmit a stream of air between the two voice chords.
The air causes the voice cords to vibrate. The sound comes from the vibrating vocal cords. The vibration of the vocal cords generated by ejected air produces vocal sounds.
As a result of the previous explanation, the following points may be made to comprehend human sound production:
The Voice Box is responsible for producing sound in humans. This is the place where a firm bump will travel up and down anytime you swallow something.
The vibrations which arise in the larynx are thus responsible for the production of sound in humans.
Human Sound Working System
The system which produces the human voice can be divided into three main parts:
Lungs
Lungs are a pair of air-filled organs that are squeezed together.
Both sides of the chest are attached.
Articulators
The tongue, upper and lower lips, gums and teeth, and the glottis are some of the articulators.
The vocal folds inside the voice box
Larynx
The larynx is also referred to as the body’s voice box.
The voice is produced by that region of the body.
It can be found in the human body’s neck region.
The larynx, popularly known as the voice box, is a hollow, tubular structure attached to the top of the windpipe (trachea), by which the air flows on its approach to the lungs. The larynx is also responsible for producing vocal sounds and preventing food and other foreign particles from entering the lower respiratory passages.
The larynx has an exterior skeleton of cartilage plates which prevents the structure from collapsing. Membranes and muscle fibres bind the plates together. Thyroid cartilage, the front set of plates, contains a central ridge and elevation known as the Adam’s apple. From the age of about 20 years old onwards, bone cells tend to replace the plates.
The epiglottis is a flaplike extension into the throat at the top of the larynx. When food is ingested, the entire larynx structure moves to the epiglottis, blocking the respiratory tract channel. The larynx relaxes and returns to its natural position once food goes into the oesophagus (food tube).
Human voice
Talking, singing, laughing, crying, screaming, shouting, humming, or yelling are all examples of sounds created by a human using the vocal tract. The vocal folds (vocal cords) are the fundamental sound source in human voice frequency. (Other sound-producing mechanisms include unvoiced consonants, clicks, whistling, and whispering, all of which originate from the same general area of the body.)
The lungs, the vocal folds within the larynx (voice box), and the articulators are the three elements that make up the process for producing the human voice. To vibrate vocal folds, the lungs, or “pump,” must provide sufficient airflow and pressure. The vocal folds (vocal cords) then vibrate to create audible pulses from airflow from the lungs, forming the laryngeal sound source. To ‘fine-tune’ pitch and tone, the muscles of the larynx change the length and tension of the vocal folds. The articulators (tongue, palate, cheek, lips, and other components of the vocal tract above the larynx) articulate and filter sound coming from the larynx, and to some extent may interact with the laryngeal airflow to strengthen or decrease it as a sound source.
The vocal folds of adult men and women are typically of varied diameters, reflecting the male-female variations in larynx size. Male voices are typically lower-pitched and have greater folds throughout adulthood. Male vocal folds are between 17mm and 25mm in length (as measured vertically in the opposing picture). The length of the female vocal folds varies between 12.5 and 17.5mm .
Conclusion
Sound is essential for communicating information, connecting with others, making art, keeping track of schedules, and a variety of other activities. A sound is a type of vibrating energy that moves through air or any other medium. A quick to-and-fro or up-and-down movement around a mean location is described as vibration.
The speech box, also known as the larynx, is used by humans to make sound. The voice box is located at the tip of the windpipe in our neck. The vocal cords are two ligaments in the human voice box. The waves of the vocal cords make sound.
