“X” is used for the left ear and “O” represents scores for the right ear. The scores are compared to results obtained from persons with normal hearing (i.e. the line at 0dB). Bone Conduction. Sometimes the audiogram will also show bracket symbols “[” and “]”. These represent scores based on bone conduction tests.
SNR Loss Category Technology Needs 0–2 dB Normal Omni-directional microphones 2–7 dB Mild Fixed/dynamic directional microphones Although 0-20 dB HL is marked as ‘normal’ range of hearing on audiograms, children who typically hear from -10 to +10 dB HL begin to be effected educationally at hearing levels above 15 dB HL. The hearing loss range between 16-25 dB is considered “slight”. Audiogram Symbols. An "O" often is used to represent responses for the right ear and an "X" is used to represent responses for the left ear. A key on the audiogram, similar to one found on a map, identifies what the different symbols mean. The pitches shown on the audiogram are those most important for hearing and understanding conversation.
Over 40 – 2 Years. Comprehensive. Siemens Healthineers China|2018-04-30. A 3-year old needed high resolution CT for investigation of sudden hearing loss. A 3-year-old girl was presented to 30. 4.
As we age, it’s the upper frequencies we lose first. The commonly stated range of human hearing is 20 to 20,000 Hz. Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea.

We use an audiogram, which is a graph to document results from the hearing evaluation. It demonstrates how softly a person can hear certain sounds. The graph shows frequencies (pitches) and loudness (decibels). Behavioral Hearing Tests.

Types of Hearing Loss; Configuration of Hearing Loss Audiogram – Interpreting results An audiogram represents an individual’s hearing ability by frequency (pitch) and intensity (volume). The softest sounds that a person can hear at a particular frequency is called their hearing threshold . It’s not abnormal, and it depends on the amplitude variation allowed. If this was information given to you by an audiologist, you should have a good idea how flat that curve is, and how quickly it drops off at higher frequencies.

Elever med normal hörsel måste höra ett ord upp till 40 gånger för att känna till ordet så Ett CI höjer oftast hörseltröskeln till 20–30 dB (Saarinen & Lonka, 2010), vilket betyder Speech sound production in 2-year-olds who are hard of hearing.
