The limit term has several applications. It is used to name, for example, the entrance or the initial movement of something: “Please, tell your brother to come in, he does not have to stay on the threshold of the house”, “The thief hid on the threshold and , when the victim left for work, he took advantage and went home”, “The team is on the cusp of a new title”.
In this sense, we can also establish that there is an expression that is related to said meaning. We refer to the verb phrase crossing the threshold. By this, what is meant is that someone in particular entered a house or building by chance. Threshold is the lowest or lowest value of a quantity that can generate a given effect. In another sense, the threshold is the smallest amount of signal that must exist to be perceived by a system.
The notion of threshold is linked to the physical possibilities of sensitivity. The threshold is determined as the lowest intensity level of a stimulus that has a fifty percent chance of being recorded. When the stimulus can transmit a nerve impulse, it is considered the threshold. Therefore, the threshold of hearing is called the lowest intensity of a sound that a person’s ear can detect. The normal value is between zero and 25 audiometric dB. Other thresholds linked to hearing are the pain threshold (sound intensity that, when exceeded, causes damage to the ear) and the masking threshold (linked to the pressure level). Likewise, we cannot ignore the existence of what is known as the threshold of death. Term used to define the experience lived by those people who, due to various circumstances, go through a moment of coma or cardiac arrest during which they claim to have seen the familiar light that led them to leave this world. However, they eventually manage to survive and remember that moment. There are several books on the subject, such as the one entitled “Death: a dawn”. Dr. Kübler-Ross is the author of the aforementioned narration in which she deals in depth with the aforementioned topic where she, among other things, states that only 10% of the people who were at that threshold clearly remember this experience.
