a graphic representation of auditory sensitivity (hearing threshold levels in decibels [dB]) for pure tone sound plotted as a function of test frequency in cycles per second (hertz, Hz). The audiogram is useful in defining degree of hearing loss.
A graph showing absolute threshold for pure tones as a function of frequency. It is usually plotted as hearing loss in dB as a function of frequency, with increasing loss plotted in the downward direction
A graphic representation of the minimum detectable level of a sound (threshold) as a function of sound frequency. Usually expressed in decibel (dB) hearing level (HL,) where 0-20 dB HL is considered as the “normal” range of hearing thresholds.
This is a graph used to designate the student's response to sound. Symbols are used to plot an individual's ability to hear pitch and loudness of tones and environmental sounds, and to comprehend spoken language.
The audiologist does an audiogram (sometimes called audiometry) to determine the softest levels that a child can hear across low and high pitches. Often, the audiologist will also assess how well the child perceives speech sounds, which is called speech perception testing. Additionally, the audiologist may measure how softly a child can understand speech.
A chart, graph or table resulting from an audiometric test showing an individual's hearing threshold level as a function of frequency. Pure tones of specific frequencies are used to conduct the audiometric test.
A graph on which a person's ability to hear different pitches (frequencies) at different volumes (intensities) of sound is recorded. UDIOLOGICAL ASSESSMENT: A hearing test comprised of identifying pure-tone thresholds, impedance testing, speech recognition, and speech discrimination measurements, which shows the type and degree of hearing loss. The test can also assess how well the child is hearing with amplification.
This is a graphic representation of a person's hearing thresholds. Typically, horizontally, across the top of an audiogram, are the different frequencies (think "the pitch of the tone I heard") from 250 Hz ("low tone") to 8000 Hz ("high tone"). Typically, vertically, down the side, are the decibels (a unit of measurement) from 0 to 110 dB (think of a volume control, the bigger the number, the louder the sound that was presented). There should be a "key" to tell you what each symbol on the graph means.
The method of determining a persons threshold of hearing. The amount of hearing loss can be determined from an audiogram. The audiogram is typically the detection of a tone at its lowest perceivable level. The tones are at industry designated frequencies.
