The noise generated by one or more people is called noise.
The notion of bulla comes from bubbling . This verb has several uses: the first meaning mentioned in the dictionary of the Royal Spanish Academy ( RAE ) refers to boiling .
When a thing or a group of animals or people shake with movements similar to those made by water when it boils , we can also talk about boiling. From these meanings, the concept of bulla is developed.
What is the noise
According to the RAE , the hustle and bustle produced by people is called noise, whether alone or together. The noise can be associated, in this case, with noise .
For example: “How much noise the women sitting at that table make! The waiter should ask them to lower their voices,” “The noise from the neighbors didn't let me sleep all night,” “I can't understand how the police didn't hear the noise the fugitives made when they escaped.”
Noisiness is considered normal in certain contexts. At a football match with thousands of attendees or at a massive concert , the audience will always make noise with shouts, applause, etc. No one could be surprised by this situation. On the other hand, if someone organizes a party on a Wednesday night at their house with loud music and dozens of guests, there will be a commotion at the event that will disrupt the usual calm and the neighbors will not be able to rest. In this framework, the noise violates the rights of those who live near the meeting place.
The concept in health
In the field of medicine , bulla is used as a synonym for blister . The bulla is an injury that occurs in the epidermis from a defensive mechanism of the body.
The body itself generates the bulla in the skin in order to provide protection to the inner tissue. The blister, in this way, is an inflammation that fills with fluids and that contributes to the regeneration of an area affected by friction or a burn.
The pulmonary bulla is a type of air pocket that forms in the lungs.
The pulmonary bulla
A space in the lungs that is filled with air is called a pulmonary bulla . This formation occurs when the alveolar walls are damaged.
Pulmonary bulla can appear due to chronic obstruction or be congenital. If this type of air sac breaks, it can cause a spontaneous pneumothorax .
This noise is common among those who suffer from emphysema . They can also occur in patients with Marfan syndrome , AIDS , and other disorders and diseases .
Naming of different ancient objects
Thousands of years before Christ, in the region of Mesopotamia , an object that was used to record barter was called a bulla. It was a type of seal consisting of a sphere with representations of animals inside.
At that time, it was common for commercial operations not to involve the immediate delivery of merchandise (usually livestock ). In those cases, the noise allowed the transaction to be remembered: a number of figures representing the specimens involved were placed inside, then the sphere was sealed and finally some marks were made on its external part.
In Ancient Rome , meanwhile, the bulla was a medallion that contained an amulet . This pendant was placed on children nine days after birth as it was considered to provide them with protection against evil spirits.
