This is not the best threshold found for all subjects, under ideal test conditions, which is represented by around 0 phon or the threshold of hearing on the equal-loudness contours, but is standardised in an ANSI standard to a level somewhat higher at 1 kHz . There are several definitions of the minimal audibility curve, defined in different ...
A pure tone audiometry hearing test is the gold standard for evaluation of hearing loss or disability. [ medical citation needed ] Other types of hearing tests also generate graphs or tables of results that may be loosely called 'audiograms', but the term is universally used to refer to the result of a pure tone audiometry hearing test.
A negative Stenger result indicates that the patient responded to the signal presented to the better ear, indicating an organic asymmetric hearing loss. A positive Stenger result indicates that the patient did not respond even though the signal was 10 to 20 dB above the better ear, indicating a non-organic hearing loss. [4]

Sensorineural hearing loss (SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ (cochlea and associated structures), or the vestibulocochlear nerve (cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss.
The severity of hearing loss varies and can change over time. It can affect one ear (unilateral) or both ears (bilateral). Degrees of hearing loss range from mild (difficulty understanding soft speech) to profound (inability to hear even very loud noises). The loss may be stable, or it may progress as a person gets older. Particular types of ...
The shape of the audiogram resulting from pure-tone audiometry gives an indication of the type of hearing loss as well as possible causes. Conductive hearing loss due to disorders of the middle ear shows as a flat increase in thresholds across the frequency range. Sensorineural hearing loss will have a contoured shape depending on the cause.
CRE-C20. These newly-released OTC hearing aids are packed with prescription-grade technology for less than $1,000. The Sony CRE-C20 are incredibly discreet within the inner ear, though the tiny ...
