What is audiometry used for: definition, best producer, and working principle

What is audiometry used for ? Audiometry is a technique used to measure the hearing capacity of the ear or the ability to hear sounds. which consists of three parts: mechanical sound transmission (middle ear function) neural sound transmission (cochlear function) and speech discrimination ability (central integration). audiometry used for many platform hospital and personals clinic etc.

What is the producer of audiometry Audiometry consists of tests of the auditory system or hearing function. This includes tests of mechanical sound transmission (function of the middle ear), neural sound transmission (function of cochlear), and speech discrimination ability (function of central integration). A complete evaluation of the patient’s hearing loss should be carried out by trained personnel using specially designed equipment for this purpose.

What are the types of audiometry? Various audiometric techniques are used to identify a person’s hearing ability. 1) Pure tone audiometry. 2) Speech audiometry. 3) Supra threshold audiometry. 4) Self-recording audiometry. 5) Impedance audiometry. 6) Computer Administered (Microprocessor) Audiometry. 7) Subjective audiometry. 8) Objective audiometry.

What is the working principle audiometry The pure tone audiometric air conduction test is performed by means of an earphone to deliver pure tone to the ear and measure the lowest intensity in decibels (dB), at which the tone is perceived 50% of the time. This measurement is called the threshold. The test procedure is repeated for each ear at specific frequencies of 250 to 8000 Hz (Hz, or cycles per second), with the thresholds recorded on a graph called an audiogram.

How to perform audiometry test An audiogram is a graph that shows the frequency in hertz on the abscissa and the hearing threshold in decibels at the frequency. The zero level on an audiogram is an arbitrary sound pressure level that indicates ideal normal hearing in young adults. A hearing test is a measure of a patient’s ability to hear and understand speech. The Speech Reception Threshold (SRT) is the lowest decibel level at which a patient can repeat 50% of the test words correctly.
