2020-01-05 normal if it falls in the range of -10 to 25dB HL (Hearing Level). Even though an individual might obtain a value within this normal range, this does not always mean that he has completely normal hearing acuity. For example, it is possible that the individ-ual’s thresholds in one ear are 15dB, 25dB, and 35dB HL … If a bone conduction test is also needed, the results will be marked using a blue > line for the left ear and a red < line for the right (not pictured below). The difference between the results of air conduction and bone conduction tests is known as the air-bone gap. An air-bone gap may mean a problem in the outer or middle ear. 2020-04-04 GENERAL: Audiograms are used to diagnose and monitor hearing loss. Audiograms are created by plotting the thresholds at which a patient can hear various frequencies.

During testing, the non-test ear is masked by gently occluding the auditory canal Hz and plotted on a pure-tone audiogram with the test frequency al audiometry revealed hearing sensitivity within normal limits for the right ear and moderate sloping to severe sensorineural hearing loss for the left ear (see Figure 3) The audiogram is a visual picture of what the ear hears. Thresholds of 0-25 dB are considered normal for adults and thresholds of 0-15 dB are considered The microscopic examination of the ears yields normal findings.

Looking at the audiogram, normal hearing is represented at 25 dB and above from left to right. If your threshold symbols (X and O’s) fall in this area, your hearing ability is considered within normal limits. Any symbols below that area, however, indicate hearing loss at those frequencies.

If your threshold symbols (X and O’s) fall in this area, your hearing ability is considered within normal limits. Any symbols below that area, however, indicate hearing loss at those frequencies.

An audiogram can show if you have hearing loss, what type of hearing loss you might have, and it can help identify an appropriate hearing solution. Normal bone conduction thresholds indicate that this 30dB air-bone gap is a case of mild-to-moderate conductive hearing loss. ADHEAR would be an effective non-surgical solution for temporary conductive hearing loss, or chronic conditions such as damaged ossicles, chronic otitis media, or other causes of conductive hearing loss. The Audiogram An audiogram is a diagram used by hearing professionals to show visually how well you can hear. An audiogram can show if you have hearing loss, what type of hearing loss you might have, and it can help identify an appropriate hearing solution.

Conductive – Normal hearing for bone conduction scores ([ & ]), and a hearing loss for Air Conduction scores (X & O). Identifies a blockage, infection, or physical damage within the outer-ear or middle-ear. There is a normal range.0dB to 20dB = Normal range21dB to 40 dB = Mild hearing loss41 dB to 55 dB = Moderate hearing loss56 dB to 70 dB = Moderately Severe hearing loss71 dB to 90 dB = Severe hearing loss> 90 dB = Profound hearing loss.

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). The right ear is plotted as < and the left ear as >. Common measures: Threshold = the lowest level of sound that can be heard 50% of the time.
