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.
Shawna Kay – Mom of two children in care. My youngest isn’t quite 1 yr old yet. How much more difficult do you need to make it for us? I barely make enough to cover daycare as it is, and that’s WITH subsidy! The ripple effect here is going to negatively impact so many. Please think of how much these changes are HURTING people who are just scraping by as it is!!!!
Spontaneous otoacoustic emissions (SOAE)s are sounds that are emitted from the ear without external stimulation and are measurable with sensitive microphones in the external ear canal. At least one SOAE can be detected in approx. 35-50% of the population. The sounds are frequency-stable between 500 Hz and 4500 Hz to have unstable volumes between -30 dB SPL and +10 dB SPL. The majority of the people are unaware of their SOAEs; portions of 1-9% however perceive a SOAE as an annoying tinnitus.

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.
