OAEs are considered to be related to the amplification function of the cochlea. In the absence of external stimulation, the activity of the cochlear amplifier increases, leading to the production of sound. Several lines of evidence suggest that, in mammals, outer hair cells are the elements that enhance cochlear sensitivity and frequency selectivity and hence act as the energy sources for amplification. One theory is that they act to increase the discriminability of signal variations in continuous noise by lowering the masking effect of its cochlear amplification.
At Bradford Early Education, we believe that children are on their own developmental journey and that children should be challenged based on their individual interests, needs and capabilities. We endeavor to prepare our children for their academic careers by using scientific principles and empirically supported methods. As a Bradford Early Education school, we teach from a unique and independent curriculum.
It has been found that distortion product otoacoustic emissions (DPOAE’s) have provided the most information for detecting mild hearing loss in high frequencies when compared to transient evoked otoacoustic emissions (TEOAE). This is an indication that DPOAE’s can help with detecting an early onset of noise-induced hearing loss. A study measuring audiometric thresholds and DPOAEs among individuals in the military showed that there was a decrease in DPOAEs after noise exposure, but did not show a shift in audiometric threshold. This supports OAEs as predicting early signs of noise damage.
My name is Kara Downing but now days I go by Miss Kara. I grew up in south eastern Colorado on a 2500 acre farm with my brother and sister. I was the youngest sibling and always wanted a younger brother or sister. As a young child I was always helping take care of my younger cousins and I loved babysitting. My grandma was an elementary teacher and I remember going to help in her classroom and the idea of teaching seemed like so much fun. I believe all of these factors helped my find my passion with working with children.
