What is hearing?
hearing screening is a testing process to determine whether an individual has a normal hearing or a certain degree of hearing loss. These tests are often performed when a child is born and regularly in childhood. Adults may also have hearing tests at their request when hearing problems are recorded, or if injuries or health conditions cause hearing loss. Hearing screening is often used to divide people into two categories: those with hearing loss and people without it. To determine how serious hearing loss and how to solve the problem, a specialist may need to help. Many places have early interventions that require doctors to often check children to identify and treat hearing problems as soon as possible. Early detection and treatment may affect how well speech in people with hearing loss and how they adapt to special techniques and programs aimed at improving their hearing or helping them to adapt to hearing loss.
If hearing loss is not detected, the consequences are serious. Children of all age groups may face learning and may be disturbed by the development of younger children. School age children can avoid social situations and classroom participation, which often leads people to believe that they have learning disabilities or are shy. Hearing loss can be insulating for elderly, contribute to emotional challenges and disrupt relationships with friends and family members.
One type of hearing screening used in infants is called test otoacoustic emissions. This test includes the location of a small microphone and headphones in the baby's ear. The sounds are introduced by a doucho over the handset and the echoes in the ear canal are picked up using a microphone. The echoes are measured to detect hearing loss.
Conventional audiometry is a type of hearing screening that is often used for children and adult school age. This test plays a number of tones that children hear throughheadphones. Children are asked to raise their hands, point to one of their ears, or press the button every time they hear one of the tones.
In most places, adults undergo voluntary screening and there are no laws that doctors require to propose it at specific intervals. However, some governments will require adult hearing tests in individuals working in a particularly loud environment. In the United States, the safety and health management defines these standards and requirements. Some hearing specialists also recommend that adults should check the hears at least once every 10 years before age. As soon as they are 50 years old, recommers often change every three years.
