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.
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.
Audiometry (from Latin audīre ' to hear ' and metria ' to measure ') is a branch of audiology and the science of measuring hearing acuity for variations in sound intensity and pitch and for tonal purity, involving thresholds and differing frequencies. [1]
An Audiometrist (from Latin audīre, "to hear"; and from Italian-metria, “to measure” ) or Audiometric Officer, is a health-care professional technician [1] who has received special training in the use of Pure tone audiometry equipment. [2]
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.
A case history (usually a written form, with questionnaire) can provide valuable information about the context of the hearing loss, and indicate what kind of diagnostic procedures to employ. Case history will include such items as: major concern; birth and pregnancy information; medical history; development history; family history; workplace ...
An audiologist is a health care provider specializing in identifying, diagnosing, treating, and monitoring disorders of the auditory and vestibular systems. Audiologists are trained to diagnose, manage and/or treat hearing , tinnitus , or balance problems.
Conditioned play audiometry (CPA) is a type of audiometry done in children from ages 2 to 5 years old, in developmental age. It is the test that directly follows visual reinforcement audiometry when the child becomes able to focus on a task. It is a type of behavioral hearing test, of which there are many.
