Spatial hearing loss refers to a form of deafness that is an inability to use spatial cues about where a sound originates from in space. Poor sound localization in turn affects the ability to understand speech in the presence of background noise.
sounds or speech becoming dull, muffled or attenuated; need for increased volume on television, radio, music and other audio sources; difficulty using the telephone; loss of directionality of sound; difficulty understanding speech, especially women and children; difficulty in speech discrimination against background noise (cocktail party effect)
difficulty understanding speech in the presence of background noise (cocktail party effect) sounds or speech sounding dull, muffled or attenuated; need for increased volume on television, radio, music and other audio sources; Hearing loss is sensory, but may have accompanying symptoms: [citation needed] pain or pressure in the ears; a blocked ...
Using advanced technology, the Select 300 is designed to prioritize speech and reduce background noise to help you hear one-on-one conversations better, even in a noisy environment. On top of that ...
Although genetically variable, it is a normal concomitant of ageing and is distinct from hearing loss caused by noise exposure, toxins, or disease agents. [1] Common conditions that can increase the risk of hearing loss in elderly people are high blood pressure, diabetes, or the use of certain medications harmful to the ear.
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]
Phonemic restoration effect is a perceptual phenomenon where under certain conditions, sounds actually missing from a speech signal can be restored by the brain and may appear to be heard. The effect occurs when missing phonemes in an auditory signal are replaced with a noise that would have the physical properties to mask those phonemes ...
Thus, more noise has to be applied, to produce a masking effect. At the right hand side of the graph, to identify 50% of the speech correctly, the speech needs to much more intense than in the quiet. This is because at this end of the graph, the noise is very loud whether the person has a hearing loss or not.
