It shows the softest sounds heard at different pitches and frequencies. The audiogram helps to diagnose the degree and type of hearing loss, as well as help identify possible treatments. Type As tympanograms, with normal middle ear pressure (Pres = -20) but reduced compliance (Comp = 0.2) can represent normal middle ear function, or a stiff middle ear system suggestive of some form of ossicular fixation (otosclerosis or tympanosclerosis affecting the ossicles) with normal Eustachian tube function. The decibel scale is logarithmic (based on a factor of 10): An increase of 10 dB means a 10-fold increase in sound intensity. An increase of 20 dB means the sound is 100-fold more intense.

Audiogram of Child with Conductive Hearing Loss When the outer or middle ear is blocked or damaged, bone conduction thresholds will be better than air conduction hearing levels. Conductive hearing loss is defined as air conduction thresholds greater than 15 dB (outside the normal range) with bone conduction thresholds within the normal range. 2018-02-22
The decibel scale is logarithmic (based on a factor of 10): An increase of 10 dB means a 10-fold increase in sound intensity. An increase of 20 dB means the sound is 100-fold more intense. Standard audiograms test between 0 and 110dB. For reference, normal conversation is around 60 dB. Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels.The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal.

A normal hearing person can detect very soft sounds at 20 dB or less, like a whisper, to a very loud sound of 120 dB, like an airplane. The softest level that the child responds to the auditory signal is recorded on the audiogram. Sound field testing provides information about the hearing level of only the better ear while insert earphone testing provides information about the hearing levels of each ear. Hearing range describes the range of frequencies that can be heard by humans or other animals, though it can also refer to the range of levels.The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal.
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. Horizontal lines represent the loudness, from very soft at the top to very loud at the bottom. Ställ en fråga vänd mot dator eller dylikt. Normal samtalston motsvarar en ljudnivå på ca 20dB.

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.
