What is a Sounding device and its major functions?

The sounding device encompasse all the organs involved in the transformation of air into sound vibrations. we will discuss Sounding device and its major functions here. It is closely related to the respiratory system and its main objective is to allow human communication through spoken language.

Parts of the sounding apparatus

The phonetic apparatus consists of three groups of organs.

Breathing organs


The lungs are the largest organs of the human body and their main function is to allow inspiration and expiration of air . They are formed by connective tissue inside which are the bronchial tubes, which progressively branch off from the trachea.


The bronchi are the ducts that arise from the bifurcation of the trachea . Each of the bronchi is connected to one of the lungs. The air enters through the trachea and reaches the lungs through the bronchi, so that its role is very important.


The trachea is one of the most important elements of the respiratory system. It is the tube that connects the nose and mouth with the lungs and bronchi . It is shaped like a tube and consists of a set of carilaginous rings. It begins in the larynx and runs to the chest.

Phonation organs


The larynx is a tubular organ formed by a total of six cartilage . Connect the pharynx with the trachea. This is the organ of phonation because the vocal cords are located in the larynx.

Vocal chords

The vocal cords are the element of the phonological apparatus responsible for the production of the voice . Despite their name, the truth is that they have no rope shape, but are a set of folds. They are a total of four, divided into two large groups: true and false . The false ones do not participate in the production of sounds, while the true ones do.


The resonators are responsible for the vibrations that come from the vocal cords become sound.

Articulation organs



The palate is the upper wall of the oral cavity . It is divided into two parts: the bone palate and the veil of the palate. Its main function is to separate the oral cavity from the nostrils and its interaction with the tongue allows the articulation of sounds.


The tongue is a mobile organ that is inside the mouth. It has a key role in numerous functions, such as mouth hydration , swallowing or language, among others. It is characterized by its cone shape.


In the case of adults, they have a total of 32 teeth : 8 incisors, 4 canines, 8 premolars and 12 molars. It is interesting to know that not all adults have wisdom teeth since there is not always enough room for growth.


The lips are essential to carry out a large selection of functions, such as sucking or kissing, among others.


The glottis is the narrowest part of what is called laryngeal light , a space limited by the vocal cords. Before the vibration of the vocal cords, the sound is transformed into voice or loudness. Thus, when they do not vibrate what is called dull sound is produced.
