Audiogram Interpretation As someone new to conducting hearing tests, you might find the process of uncov-ering various types of hearing disorders somewhat mysterious. An audiogram is a graph or chart that displays the results of your hearing test.Initially, it might look like a bunch of indecipherable lines and symbols. But once you learn how to read and interpret your audiogram, you will better understand your hearing loss.Even more important, your hearing care professional will use the results to help determine the best type of hearing aid for you. The graph to the left represents a blank audiogram illustrates the degrees of hearing loss listed above. Where the patient's results fall on the audiogram indicate the different degrees of hearing loss. An audiogram is the result of a hearing test and it shows you the extent of any hearing loss in either ear. Every 6 months, prior to audio evaluation. Starting on the left-hand side, frequencies ascend from a low of 125 Hz to a high of 8,000 Hz. If you continue browsing the site, you agree to the use of cookies on this website.

When asymmetrical hearing loss exists, it is best to h… Clipping is a handy way to collect important slides you want to go back to later. The range tested covers the entire speech spectrum. Kramer6notes TEOAEs are recorded during the silent intervals between brief broad-spectrum transient clicks, which activate a wide portion of the basilar membrane. Audiometry is a relatively simple procedure that can be performed and interpreted by a trained health care professional. This normally occurs between 51-70 years of age. In clinical practice, the most common OAEs recorded are Transient Evoked Otoacoustic Emissions (TEOAEs) and Distortion Product Otoacoustic Emissions (DPOAEs). This is more unusual and signifies that the causes of the loss in each ear are different and therefore must be treated differently. 5. Do we have enough information to know if it is a sensorineural, conductive or a mixed hearing loss? Now customize the name of a clipboard to store your clips. If so, share your PPT presentation slides online with PowerShow.com. audiogram reveals pure-tone averages (PTA) of 47dB hearing loss and 45dB HL for the right and left ears, respec-tively. Asymmetrical hearing loss is when each ear has a different level or type of hearing loss. An audiogram is set up as a chart with the horizontal X-axis representing frequencies, or Hertz (Hz). The test procedure and the interpretation of the results are typically done by an audiologist. The PPT itself takes approximately 15 minutes in total to administer, and requires a HINT system, a 2-channel amplifier and two loudspeakers. See our User Agreement and Privacy Policy. The numbers along the X-axis represent commonly tested frequencies, as measured in hertz (Hz). Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. Conventional pure-tone testing is used for adults Monitor the effectiveness of the hearing conservation program See our Privacy Policy and User Agreement for details. Understanding how hearing loss is recorded on an audiogram can help you better understand implications of the loss. If the 2nd word is correct continue dropping by 10 dB When 2 consecutive incorrect responses are obtained.Increase 10dB and Explanation of the audiogram and immittance tutorial PPT. See our Privacy Policy and User Agreement for details. The intensity scale in HL increases downwards, and hence the audiogram resembles like an attenuation response, a lower point on the audiogram indicating higher loss. Clipping is a handy way to collect important slides you want to go back to later. Great! Hearing Loss is defined by… Degree/Magnitude of Loss Normal, slight, mild, moderate, moderately-severe, severe, profound Type of Loss Conductive Sensorineural Mixed Configuration of Loss Flat, rising, sloping, precipitous The closer the marks are to the top of the graph, the softer the sounds that person can hear. It is important that the competent person carrying out, or responsible for, the test (the tester uses professional judgement when deciding on the particular approach to be “For an individual test subject, a single audiogram is an unconfirmed determination of that individual’s state-of-hearing in both ears. Typical latencies (from click presentation to OAE recording) are perhaps 5 to 15 millisec… Measurement of Hearing and Audiogram Interpretation. Play is usually used at 3-4 yr of age.

Necessary maintenance for An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies. ®First what numbers do we use ®Pure Tone Average nTraditional - average threshold at 500, 1000, and 2000 Hz ®Example: 500 Hz = 25 dB; 1000 Hz = 35 dB; 2000 Hz = 45 dB - PTA = 105 / 3 = 35 dB nHigh Frequency - Add 4000 Hz Determine WHERE the … Interpreting the tests – Audiogram and Tympanogram. See our User Agreement and Privacy Policy. What is an Audiogram? … and the recommended format for audiogram forms. Determine degree of hearing loss by reading threshold points from left to right (250 Hz – 8000 Hz) on the audiogram. You can change your ad preferences anytime. 3. The audiogram is a picture of the type (conductive, SN, or mixed), degree (mild, moderate, severe, or profound) and configuration, or pattern, of hearing loss What is the degree of loss? Before you go, it may be helpful to know what to expect during the test. Purposes of audiometric testing. The Audiogram. Tympanometry is a test of middle ear functioning. Unformatted text preview: Audiogram Interpretation Practice 1. The speech recognition threshold (SRT) is the lowest level at which a person can identify a sound from a closed set list of disyllabic words.. Frequency is plotted at the top of the graph, ranging from low frequencies(250 Hz) on the left to high frequencies (8000 Hz) on the right. 4 Audiogram Interpretation Basic Audiology Series Audiogram Interpretation nDetermining Degree of Hearing Loss ®How do we describe the degree of hearing loss? It looks at the flexibility (compliance) of the eardrum to changing air pressures, indicating how effectively sound is transmitted into the middle ear. SRT Method Continued ASHA: Present at 30-40dB above estimated SRT Present a word at the starting level and decrease in 10 dB steps for each correct response If an incorrect word is repeated, present another word.

Bone Conduction A/C Via TDH-50P headphones Placed on Pinna Checks the validity of entire ear system Tests that ipsilateral ear B/C Bone vibrator Placed on Mastoid Process Tests the validity of only the inner ear Tests better cochlea On the audiogram sensory hearing loss is demonstrated by decreased air-conduction thresholds equivalent to decreased bone-conduction thresholds. An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies. The PPT-based counseling takes about 10 minutes, and requires the clinician to enter the patient's audiogram and PPT scores into an Excel spreadsheet. Audiometry class by Dr. Kavitha Ashok Kumar MSU Malaysia, No public clipboards found for this slide, Student at AMALA INSTITUTE OF MEDICAL SCIENCES, Medical Doctor at Gov- united republic of Tanzania. Ozarks Technical Community College 2. When showing the SRT in graph mode the speech audiogram calculates the SRT value based on the norm curve (the distance in dB from the point where the norm curve crosses 50% to the point where the speech curve crosses 50%) like shown below. Since each of these PTA values for each ear, we can state with good certainty that the SRT and PTA findings agree with each other, and therefore appear to be reliable. Moderate Hearing Loss is when the quietest sounds that a person can hear measure between 41 and 70dB HL. Ozarks Technical Community College. If your graphs or lines look different, you have asymmetrical hearing loss. Assessment of hearing (with self assessment questions). ALWAYS: the AC threshold determines the DEGREE or extent of the of hearing loss (not the BC threshold). On the right side of the "divide" are the high frequencies .

The X-axis is divided into two parts: On the left side of the "divide" are the low frequencies. Put more starkly, a single audiogram is a guess.” The recent studies by Southampton Solent University suggest that the typical variability of pure tone audiometry is greater than previously thought. How to read an Audiogram and How to Understand Your hearing test results...what do they mean? TEOAEs. Interpretation of audiogram • 1. The word recognition score (WRS) testrequires a list of single syllable words unknown to the patient to be presented at the speech recognition threshold + 30 dBHL.The number of correct words is scored out of the number of presented words to give the WRS.
