The Latin word volūmen has driven the emergence of the concept of volume , a word that describes the thickness or size of a certain object . Likewise, the term serves to identify the physical magnitude that informs about the extension of a body in relation to three dimensions (height, length and width). Within the International System , the corresponding unit is the cubic meter (m3) .
Likewise, a widely used meaning of this term in our daily lives is the one used in the workplace as a synonym for quantity. Thus, for example, it is common to say: "This company in which Manuel operates is characterized because it has a significant volume of work compared to its most direct competitors."
It should also be noted that you can talk about volume when you want to focus on the intensity that a sound that is played on some audio equipment or that is emitted under any conditions can have and when you want to mention the volumes of a book. bound . In the field of geometry , we speak of volume when addressing the space occupied by a certain body, while for numismatics , it is the thickness of a coin or medal.
Volume in physics
It is also interesting to note that, as a physical magnitude, three types of volume units are recognized: those of solid volume (used to measure the volume of a body by means of length units that are raised to the third power), the of liquid volume (developed to establish the volume occupied by a liquid contained within a container ) and aggregate volume units or capacity units (which allow calculating the volume occupied by crops stored in silos and granaries).
Regarding the different units of measurements that the International System of Units establishes, we can emphasize that in the case of solid volume we find the cubic meter, the cubic kilometer, the cubic hectometer or the cubic decameter. However, the English system establishes the cubic inch, the cubic foot or the cubic mile, among others, as measurements.
For its part, this system determines that the measurements that must be used to calculate the liquid volume are the liter, the kiloliter, the centiliter, the decaliter or the milliliter, for example. The English, as in the previous case, and the Americans have their own measurements and in this case they are the barrel, the quart, the pint, the liquid ounce, the tablespoon or the cup.
The perception of sound
As far as sound is concerned, volume is a subjective perception of man in relation to power . The intensity of a sound is established from the amount of energy (called acoustic power) that passes through a surface per second. The higher the power, the louder the volume. One fact that should always be kept in mind is that volume and loudness are not synonyms, since the latter gives its name to how intensity is subjectively perceived.
Volume level is measured in decibels (dB) , which is a logarithmic unit. As a convention, it has been established that the hearing threshold of 0 dB is equivalent to a sound that has a pressure of 20 micropascals.
In this sense, it must be made clear that the fact that people may be subjected to high decibels brings with it negative effects such as stress, lack of concentration, irritability or various depressive symptoms. And all this without forgetting, of course, physical consequences such as headaches, hearing problems, insomnia, fatigue, hypertension, increased glucose and even various digestive problems.
