A hearing test is an integral part of the ear test to determine your ability to recognize sounds by measuring the ability of sound to reach the brain. All sounds start a vibration that occurs in a liquid medium, such as air, water, and solid even in the space around us. These vibrations produce sound waves that vibrate or resonate at a fixed rate or frequency and have a fixed height, or amplitude. The frequency and amplitude are determining factors in whether the sounds we hear are either low or high set pitch. When the sounds reach your ear ear means that the sound impulses, which are sent to the brain where the brain decodes them into sound.
How are these impulses sent to the brain? Sound waves enter the ear through the ear canal where they strike the eardrum. This organelle located in the ear canal and the middle ear. When sound strikes the drum a little off the drum to vibrate Magnifying sound, which is then sent to the inner ear. Once in the inner ear, which is filled with fluid, the sound causes the fluid to move that turns tiny hairs, or cilia in the inner ear. This bending creates nerve impulses that are sent to the brain and interpreted as sound.
As we age it is not uncommon for hearing loss to occur. It is also a common problem for people in jobs where the noise level is extreme. Some of these activities are manufacturing, Airport Ground crews and nightclub workers. If you are older or have a job where the noise level is extreme the longer you should worry about regularly test your hearing to cover losses before it becomes serious.
A specialist or audiologist performs the usual hearing test. Most of these tests, you will respond to a series of sounds or words. These tests are especially important for children because children with hearing disabilities will be unable to have a proper speech development. In addition, behavioral and learning problems may be the result of poor hearing. This is so important that all children born in hospitals need to have hearing tests to catch problems early in life.
Before hearing exam starts audiologist will check your ears for the wax before and will remove the hardened wax. The tests use different and can be several types. The whispered speech test is simple and is used frequently. It consists of the tester ask you to cover one ear at a time with one finger while they stand behind you and whisper a series of words. The words are whispered you are asked to repeat the tests Beck. The pure tone Audiometry test uses a device called an audiometer that plays different tones through a set of headphones. You put the headphones on his head. The tester will then play a series of tones, all of which vary in pitch and loudness. As you hear the tones that you will respond to either raise your hand when you hear it or you have to press a button. Since this is done tests will build a graph of your answers that will show if there is a significant loss and, if so, how severe it is.
