Free field audiometry is a type of hearing test that evaluates an individual’s hearing ability in an open environment without the use of headphones or earplugs. It is a non-invasive and painless procedure that helps audiologists and healthcare professionals assess the type and severity of hearing loss a person may be experiencing.
The test involves the use of a speaker system that generates sound waves at different frequencies and volumes. The sound waves are transmitted through a room that is specially designed for this purpose, and the individual undergoing the test sits in the center of the room. The speaker system generates sounds at different frequencies and volumes, and the individual is asked to respond whenever they hear a sound.
The results of the free field audiometry test are typically displayed on an audiogram, which is a graph that shows the individual’s hearing ability in different frequency ranges. The graph has two axes, one for frequency and the other for loudness, and it is divided into four quadrants representing different types of hearing loss.
The test is useful for detecting a wide range of hearing problems, including sensorineural hearing loss, conductive hearing loss, and mixed hearing loss. It is particularly useful for evaluating the hearing ability of infants, young children, and individuals who are unable to wear headphones or earplugs due to medical conditions.
Free field audiometry is a valuable tool for assessing hearing ability, but it is not a substitute for a comprehensive hearing evaluation conducted by a qualified audiologist or healthcare professional. It is important to seek professional advice if you suspect that you or someone you know may be experiencing hearing loss or other hearing-related problems.
In conclusion, free field audiometry is a safe, non-invasive, and effective method for evaluating hearing ability. The test is particularly useful for assessing the hearing ability of infants, young children, and individuals who are unable to wear headphones or earplugs. If you suspect that you or someone you know may be experiencing hearing loss or other hearing-related problems, it is important to seek professional advice and undergo a comprehensive hearing evaluation.
