Conductive hearing loss has normal bone-conduction thresholds, but of young age or other conditions cannot undergo pure tone audiometr An audiogram is a test in which sounds are played through headphones, to one ear at a time. You are asked to respond if you are able to hear each sound.

The Bottom Line The audiogram is an important test to measure how well you can detect sounds and to determine if you have a hearing loss. 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) Ett normalt samtal har en frekvens mellan 500 Hz och 3 000 Hz. Resultaten i ett audiogram markeras med röda cirklar för höger öra och blå kryss för vänster öra vid ett hörseltest.

Ett audiogram är ett diagram som används av hörselspecialister för att visuellt kunna visa hur bra du kan höra. Ett audiogram kan visa om du har en hörselnedsättning, vilken typ av hörselnedsättning du har och den kan hjälpa dig att identifiera en lämplig hörsellösning.

The audiogram at age 27 is considered the baseline since it shows the best hearing threshold levels. Asterisks have been used to identify the baseline and most recent audiogram. A threshold shift of 20 dB exists at 4000 Hz between the audiograms taken at ages 27 and 32.

Along the left side are numbers representing decibel levels (-20dB to +120dB).

Audiograms are set out with frequency in hertz 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 and 15 dB, although 0 dB from 250 Hz to 8 kHz is deemed to be 'average' normal hearing. Hearing thresholds of humans and other mammals can be found with behavioural hearing tests or physiological tests used in audiometry. For adults, a behavioural hearing test involves a tester who presents
