Otosclerosis Question 3:Based on this audiogram and knowing the patient had normal tympanometry, WHY do you think the disorder causing this Even if your audiogram is “normal for your age”, it might not be “clinically normal”. There are three types of age-related hearing loss; two (Type 1 and Type 2) are detected by the audiogram. Type 3, which is related to nerve damage, may not be detected by the audiogram. A hearing threshold of between 0 and 25 dB is considered normal.

Any symbols below that area, however, indicate hearing loss at those frequencies. Audiograms are set out with frequency in hertz (Hz) on the horizontal axis, most commonly on a logarithmic scale, and a linear dBHL scale on the vertical axis. For humans, normal hearing is between −10 dB (HL) and 15 dB (HL), although 0 dB from 250 Hz to … The pictures and letters represent the sounds a hearing person can normally hear at different volume and pitch levels. That ranges from the very soft, like a whisper, to the very loud, like a plane. The blue X line shows the left ear results from an air conduction test. The red O line shows the right ear results.

The levels of hearing loss are generally classified as mild, moderate, severe or profound. Hearing loss that borders between two categories is typically described as a combination of the two categories (for example, thresholds at 60 dB HL might be called moderate-to-severe). In this installment of our educational series on hearing loss, we’ll take a closer look at the components that make up an audiogram.

The "o" sound is low in pitch and louder. The audiogram illustrates your hearing ability by showing your hearing threshold at various frequencies. Hearing threshold is an indication of how soft a sound may get before it is inaudible. A hearing threshold of between 0 and 25 dB is considered normal. How to read an audiogram? to what is referred to as Hearing Level, abbreviated as HL. The HL unit is based on research that ascertained the amount of dB SPL needed to derive the average threshold (i.e., softest level in which a sound can be heard) at each frequency for large groups of normal hearing individuals (usually college students), the “0 dB HL level.” Users with this type of hearing loss are primarily affected in terms of sound loudness rather than clarity, as their inner ear and nerves are normal. What an audiogram of conductive hearing loss looks like; In this circumstance, bone conduction result is normal white air conduction result showing there is … Audiogram – Interpreting results.

With normal hearing, you should be able to hear the softest sounds, such as a tap dripping or birds chirping, without any difficulty. These sounds  What is an audiogram? An audiogram is often called a “hearing test,” but there's no pass or fail. It is a written -10 – 25 dB Normal hearing.

The quietest level of sound heard at each pitch is then plotted on the audiogram using a red circle for right ear and a blue cross for left ear. The position of the symbols is compared to an agreed normal hearing level of 25dB across all pitches of sound. The further down the chart the results are plotted the louder the sound had to be made.
