What is noise level?
noise level is usually defined as an amplitude of various sounds that occur in the area. In order to accurately measure the levels of noise generated in specific circumstances, various sounds, which are called decibel level, are evaluated and assigned. Categorization of noise levels in several different classes allows you to determine the potential of ear damage and also to provide information that is useful in choosing ears protection for those who have to stay in the area for a longer period of time.
The typical graph level of noise classifies different sounds based on five different categories. The first class is usually known as a weak noise level and usually carries a number of no more than 30 decibels. These are considered completely safe and are no threat at all. An example of a weak level would be a whispered exchange in the public library.
The second level of the sound noise is known as the mild . Like weak categories, even slight sounds also do not pose a threat to the human ear and JSou common. This level of noise is usually between 40 and 50 decibels, it is often pleasant and ideal for helping someone to relax. Examples of slight sound levels are stable rain or room that is more or less silence.
The third class is known as very loud . This class usually includes a range between 60 and 80 decibels. However, the evil types of this type are still considered acceptable and do not pose a real threat to hearing ability. Typical street noise in medium size is an example of very loud noise, as well as ringing alarm clock or running vacuum cleaner.
and Extremely loud noise level includes sounds that have a certain potential for causing ear damage and having a range of 90 to 110 decibels. For example, loud machines in a manufakturing plant can cause hearing loss if the ears are not used to damp the sounds. Tools such as a chain saw or large CVII also make sounds loud enough to cause damage if the exposure is taking place.
The most serious type of noise level is generally known as painful . This category is for sounds that register more than 120 decibels. The sounds in this category are able to cause temporary or even permanent hearing loss in one or both ears. A classic example of an event that creates sounds at this level is the Rock and Roll concert. A good example of noise levels that causes the loss of hearing are, along with loud music, along with the loud music that turns for take -off, a siren with an infusion or a collection used on a construction site.
In many situations where people are exposed to extremely loud or painful noise levels, wearing protective devices is considered absolutely necessary. Depending on the specific noise, the individual may be required to wear a simple stop into the ears that suppress the sound sufficiently to protect the ears. INMore serious situations may be the protection of the ear, which protects not only the ear canal, but also includes the outer part of the ear to prevent any type of auditory damage.
