The softest sounds that a person can hear at a particular frequency is called their hearing threshold. This is usually represented by markings on their graph; red represents the right ear and blue represents the left. The other way sound is measured is frequency, or pitch. It's measured in Hertz (Hz). When hearing ability is tested, a range of 250 Hz to 8000 Hz is measured because it encompasses the speech frequencies, the most important range for communication.

OBS! Under 2020 kommer jag börja göra om mina sidor här, och ta bort de sidor som är inaktuella eller inte fungerar längre, så bloggen kan se halvtom ut i  frågor i din webbläsare och svaren analyseras därefter av en audionom. Steg 3. Vi går igenom eventuella audiogram och intyg om hörselgångsstatus från dig.

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.” It should be emphasized that this problem is not unique to the WHO hearing-impairment grading system, as many others yield similar classifications for age-related hearing loss (or other sloping audiometric configurations, such as occupational hearing loss). 4 The fundamental problem for age-related hearing loss, as shown in Figure 1, is that hearing is often well within the “normal” range at the lower two frequencies (500 and 1000 Hz) included in most pure-tone averages, as is the case The pitches shown on the audiogram are those most important for hearing and understanding conversation. Each sound we hear when someone speaks has a different pitch and loudness. For example, the "s" sound is high in pitch and quiet. The "o" sound is low in pitch and louder. The audiogram illustrates your hearing by representing your hearing threshold levels at different frequencies.

An Audiogram is a graph that shows the 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.

Detta kallas för  av E Nylund · 2019 — 4000Hz. Det här kallas för better ear hearing level, BEHL (Sorri, 2000).

This means an audiogram that shows hearing thresholds below this may indicate a degree of hearing impairment. Based on what the audiogram looks like, it can help diagnose the extent of your hearing impairment and help illustrate how significant it is.
