What does the term audiometry mean?
An audiometry exam tests your ability to hear sounds. Sounds vary, based on their loudness (intensity) and the speed of sound wave vibrations (tone). Hearing occurs when sound waves stimulate the nerves of the inner ear. The sound then travels along nerve pathways to the brain.
What is the difference between audiogram and audiometry?
Hearing screening An audiometric evaluation via earphones is performed. If the results turn out positive for hearing loss, a more sophisticated audiogram (a complete audiologic evaluation) is recommended to be performed by an audiologist.
What is clinical audiometry?
Audiometry consists of tests of function of the hearing mechanism. This includes tests of mechanical sound transmission (middle ear function), neural sound transmission (cochlear function), and speech discrimination ability (central integration).
What is audiogram audiometry?
An audiogram measures hearing ability The goal of audiometric testing is to measure your hearing ability across a range of frequencies in each ear independently. This testing produces a chart called an audiogram.
How is an audiometry test performed?
The tuning fork is tapped and held in the air on each side of the head to test the ability to hear by air conduction. It is tapped and placed against the bone behind each ear (mastoid bone) to test bone conduction. A formal hearing testing can give a more exact measure of hearing.
What is audiometry in medical surgical nursing?
Audiometry is the testing of a person’s ability to hear various sound frequencies. The test is performed with the use of electronic equipment called an audiometer. This testing is usually administered by a trained technician called an audiologist.
Why do we do audiometry test?
Audiometry tests can detect whether you have sensorineural hearing loss (damage to the nerve or cochlea) or conductive hearing loss (damage to the eardrum or the tiny ossicle bones). During an audiometry evaluation, a variety of tests may be performed.
How is audiometry performed?
A hearing test is performed in a sound proof room. You will wear headphones or earplugs connected to a device that sends sounds of different volumes and pitches to one ear at a time. You will be asked to respond by raising your hand or pressing a button each time you hear a sound.
