80 Pure-Tone Audiometry Pure-tone audiometry is the cornerstone of clinical auditory assessment. It is a psychoacoustical test which aims to establish the subject's pure-tone hearing threshold levels at specific frequencies, that is, the minimum sound level at which a specific response can be obtained. It is used for the diagnosis, remedial action and rehabilitation of…

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". Audiogram Symbols. The standard symbols used in pure-tone audiometry are as follows: Right ear (red) O air conduction Left ear (blue) X air conduction Either ear (black or green)∆ unmasked bone conduction An audiogram is the graphical representation of the results of pure-tone air conduction tests. Vertical lines represent the testing frequencies, arranged from low-pitched on the left to high-pitched on the right.

PTA provides a method for separating conductive losses, located in the outer and middle ear, Ett audiogram är en graf som visar de svagaste ljuden en person kan höra vid specifika frekvenser. Pipiga ljud, till exempel fågelsång eller barnskrik, har en hög frekvens. Ljud med en låg frekvens har en djupare ton, som till exempel hundskall eller ljudet av en gräsklippare. Diagnostic standard pure-tone threshold audiometry, used most often in clinical settings, includes manual air-conduction measurements at 250, 500, 1000, 2000, 3000, 4000, 6000, and 8000 Hz (125 Hz under some circumstances) plus bone-conduction measurements at octave intervals from 250 Hz to 4000 Hz and at 3000 Hz as needed.

The results on the audiogram indicate where the ‘pure tones’ of the main frequencies (pitches) in conversational speech are, as they are heard by you. Frequencies are measured using the Hertz scale (Hz) and arranged like a piano scale moving from low pitch sounds on the left hand side of the graph, up to higher frequencies on the right side.

audiometry must produce consistent and reliable results when applied by experience audiometrists and ENT specialists. Pure-Tone Audiometry The mainstay of audiometric measurement has been the pure-tone audiogram (PTA). PTA provides a method for separating conductive losses, located in the outer and middle ear,

The lower the point on the axis, the louder the tone. The quietest tone (0 dB) is at the top of the axis. A person can normally still hear this tone. Tone frequency and pitch are read along the horizontal axis. Basic Tone Audiometry The purpose of this document is to provide a quick guide for basic functions of the AC440 Audiometry modules for the Affinity 2.0/Equinox 2.0 and Callisto™ suites. This Quick Guide will focus on Tone Audiometry as well as a basic introduction to the various icons, tools and menus available.
