Pure tone audiometry has now been in use for over 90 years and has been described as the 'Gold Standard' for the assessment of hearing thresholds.

Tone audiogram

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. The Audiogram is the graph on which we plot the results of the hearing test. Also known as the Pure Tone Audiogram.

It plots the threshold of hearing relative to an average 'normal' hearing. In this test, the ISO 389-7:2005 standard is used.

Acoustic stimuli are sounds used to determine hearing sensitivity (thresholds) and vary depending on the listener and the transducer. The Evoked and Event-Related Potentials in Hearing Research and Clinical Application.

What to expect: This little demo is not too unlike the standard audiometric test known as a pure-tone audiogram. We present pure tones of different frequencies at different sound levels, and adjust their level until they become inaudible in order to measure the "threshold".

This movement can be compared to playing on the left side of a piano and gradually moving to the right side where the tone becomes more and more high-pitched. This is because the pure tone produces sufficient basilar-membrane vibrations in neighbouring areas of the cochlea, where there are surviving IHCs and neurons. This phenomenon is defined as “Off Frequency Listening”. Clinically, this will be presented as a threshold on the traditional pure tone audiogram, but it may not be the real threshold. 2018-07-27 · This measurement involves looking at the peripheral and central auditory systems. Otolaryngologist or Otologist usually conducts pure tone audiometry test and analysis the recorded audiogram to determine the degree of hearing loss to an individual.

On the Horizontal axis are the frequencies of the sound which are presented to the patient. The frequencies tested range from 125 Hertz(Hz) up to 8000 Hz. 125 Hz is a low tone sound. 8000 Hz is a high tone sound. Humans hear frequencies from 20 Hz up to 20,000 Hz, but an audiogram only shows a subset of our hearing range: it focuses on the frequencies that are the most important for a clear understanding of speech (the spoken words). The volume (loudness) required to reach a person's hearing threshold is shown on the vertical axis (the horizontal lines).

A quiet testing environment, calibrated During testing, the audiometer delivers various “pure tone” sounds at particular frequencies and intensities, from low to high. The patient’s ability to hear these tones is plotted on a graph to create an audiogram. In children testing varies according to age: Med detta program kan man läsa in audiogram från SA 201 IV E, SA 202 IV, SA 203 IV och SA 204 IV.
