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.
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.
I have loved working with kids since I was 12, shadowing a family friend in her in-home daycare, until I began working there at 14. I grew up in that environment starting at age 9 however, so I was always familiar to the process, if not involved. She took children from 3 mo to 6 yrs, and from there I worked at a summer camp with kids age 5 to 11, where I also coordinated birthday parties based on the parents' requests. Meanwhile working with various clients throughout the years. I recently worked in a center as an Infant Supervisor, but I prefer 1 on 1 with families so I went back to nannying! I've just had a little one of my own at the end of July, and took a little time off for baby, but I'll be back to work at the end of October. When I am ready I would prefer a full time family that is okay with him coming along with me. If this will work for you, please get back to me! I will look forward to meeting you in the future!
