Glaucoma and Audiogram

How can the audiogram be more useful?

The Canadian Hearing and Auditory Research Translation (CHART) group is a newly formed taskforce to develop collaborative research initiatives. Initial discussions centered on diagnostic improvements for middle ear disease, auditory neuropathy spectrum disorder, tinnitus and presbycusis. Central to these discussions was the widely held view that the standard audiogram and its interpretation is ...

Conjoint Audiogram Estimation via Gaussian Process Classification

Audioprofile Surfaces: The 21st Century Audiogram.

OBJECTIVE To present audiometric data in 3 dimensions by considering age as an addition dimension. METHODS Audioprofile surfaces (APSs) were fitted to a set of audiograms by plotting each measurement of an audiogram as an independent point in 3 dimensions with the x, y, and z axes representing frequency, hearing loss in dB, and age, respectively. RESULTS Using the Java-based APS viewer as a...

A Pure Tone Audiogram for Students

Audiogram of the fox squirrel (Sciurus niger).

The behavioral audiograms of 2 fox squirrels (Sciurus niger) were determined with a conditioned avoidance procedure. The squirrels were able to hear tones ranging from 113 Hz to 49 kHz at a level of 60 dB sound-pressure level or less, with their best sensitivity of 1 dB occurring at 8 kHz. Their ability to hear frequencies below 150 Hz indicates that they have good low-frequency hearing, as do ...
