How do you make pure tone audiometry?
Pure tone audiometric air conduction testing is performed by presenting a pure tone to the ear through an earphone and measuring the lowest intensity in decibels (dB) at which this tone is perceived 50% of the time. This measurement is called threshold.
How do you calculate pure tone average audiogram?
Hearing sensitivity within the speech frequencies is known as the pure-tone average (PTA) and can be calculated by adding the thresholds obtained at 500, 1000, and 2000Hz and dividing the result by 3. For audiometric results to be valid, the patient must respond to stimulation of the ear being tested.
How do you plot an audiogram?
The hearing test results are plotted on a graph with the y-axis representing hearing threshold and the x-axis representing frequency. The right ear is generally plotted with a O and the left ear with a X. Bone conduction is also plotted (to allow for differentiation of conductive and SNHL).
Why it is called pure tone audiometry?
About Pure-Tone Testing It is also called air conduction testing since the sounds go through your outer and middle ear. This test helps find the quietest sound you can hear at different pitches, or frequencies.
How is pure tone audiometry test done?
Pure tone testing (audiogram) — For this test, you wear earphones attached to the audiometer. Pure tones of a specific frequency and volume are delivered to one ear at a time. You are asked to signal when you hear a sound. The minimum volume required to hear each tone is graphed.
What is the purpose in determining a pure tone average?
A Pure Tone Average (PTA) refers to the average of hearing threshold levels at a set of specified frequencies: typically 500, 1000, 2000 and 4000 Hz. This value gives a snapshot of an individual’s hearing level in each ear.

Is a tuning fork a pure tone?
A tuning fork is a fork-shaped acoustic resonator used in many applications to produce a fixed tone. The main reason for using the fork shape is that, unlike many other types of resonators, it produces a very pure tone, with most of the vibrational energy at the fundamental frequency.
What is a pure tone audiogram?
A pure tone audiogram is a graphic representation of air and bone conduction of sound. Audiograms can be very useful to the clinician in order to assess a patient’s hearing. There are three main types of deafness: sensorineural, conductive and mixed.
What is an audiogram for a hearing test?
When you have a hearing test, the audiologist will complete an audiogram. Learn more about this form. The audiogram is a graph showing the results of a pure-tone hearing test. It will show how loud sounds need to be at different frequencies for you to hear them. The audiogram shows the type, degree, and configuration of hearing loss.
What types of audiograms does answerhearform print?
HearForm prints blank audiograms in three different styles. Patient demographics are printed on forms. Patient demographics are automatically added to the form. These forms are used by those who like to fill out audiograms by hand, while testing.
