Key Takeaways: High frequency hearing loss is one of the most common forms of hearing loss. This type of hearing loss can come from noise exposure, aging, a combination of factors, in addition to ...
This type of hearing loss allows hearing at low and high frequencies, with most of the hearing loss occurring at the mid-frequencies. #5. Unilateral Hearing Loss Audiogram
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. Presbycusis or age-related hearing loss for example is characterized by a high frequency roll-off (increase in thresholds).
There are several types of hearing loss configurations (see below), with high frequency hearing loss being among the most common. A comprehensive hearing test can determine the type and severity ...
For normal hearing people this is when the masker center frequency is closest to the frequency of the test signal (See Figure 9). [ 18 ] In the case of dead regions, when the test signal lies within the boundaries of a dead region, the tip of the PTC will be shifted to the edge of the dead region, to the area that is still functioning and ...
The effect of hearing loss on speech perception has two components. The first component is the loss of audibility, which may be perceived as an overall decrease in volume. Modern hearing aids compensate this loss with amplification. The second component is known as "distortion" or "clarity loss" due to selective frequency loss. [8]
