A pure tone audiometry hearing test is the gold standard for evaluation of hearing loss or disability. [medical citation needed] Other types of hearing tests also generate graphs or tables of results that may be loosely called 'audiograms', but the term is universally used to refer to the result of a pure tone audiometry hearing test.
The results are represented by an audiogram, and are usually interpreted by an audiologist, or a registered Medical Officer, [4] unless the audiometrist is also an audiologist, with the aim of diagnosing hearing loss. There are currently some misconceptions regarding the definition of Audiometrist and Audiologist, which vary from country to ...
Portable audiometer Maico, circa 1960s. An audiometer typically transmits recorded sounds such as pure tones or speech to the headphones of the test subject at varying frequencies and intensities, and records the subject's responses to produce an audiogram of threshold sensitivity, or speech understanding profile.
Audiology in Turkey started in 1968 as an audiology master's degree program at Hacettepe University Faculty of Medicine, Department of Ear, Nose and Throat. The program, which was carried out as Audiology until 1989, has been revised since this year and continued as "Audiology and Speech Disorders" Master's and Doctoral education.
The Doctor of Audiology (AuD, sometimes written Au.D.) is a professional degree for an audiologist.The AuD program is designed to produce audiologists who are skilled in providing diagnostic, rehabilitative, and other services associated with hearing, balance, tinnitus management, and related audiological fields.
The standard and most common type of hearing test is pure tone audiometry, which measures the air and bone conduction thresholds for each ear in a set of 8 standard frequencies from 250Hz to 8000Hz. The test is conducted in a sound booth using either a pair of foam inserts or supraural headphones connected to an external audiometer.
Pure-tone audiometry is a subjective, behavioural measurement of a hearing threshold, as it relies on patient responses to pure tone stimuli. [3] Therefore, pure-tone audiometry is only used on adults and children old enough to cooperate with the test procedure.
Recruitment, in medicine, is a physical condition of the inner ear that leads to reduced tolerance of loudness.It commonly occurs in individuals who suffer hearing loss due to cochlear damage.
