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.
- "Attachment parentings can interfere with a child's need to learn about the world on his own, and his gradual emergence into his sense of independent self" (p156). Clearly, the authors have confused attachment parenting with helicopter parenting. One of the greatest outcomes of attachment parenting is confident and secure children who are not only independent, but highly inter-dependent.
In conjunction with audiometric testing, OAE testing can be completed to determine changes in the responses. Studies have found that exposure to noise can cause a decline in OAE responses. In a study, industrial workers who were exposed to 84.5 dBA of noise were compared to workers who were exposed to 53.2 dBA of noise by considering hearing thresholds and OAEs before and after 5 days of work. This study revealed that hearing thresholds and OAE results were significantly lower among the workers who were exposed to higher levels of noise.
Our highly acclaimed child care center is well known for its warmly decorated, home like learning environment. In classrooms, for example, we display pictures of children with their families above each student’s cubby, and our family-friendly atmosphere welcomes parent visits anytime during the school day. Our monthly events and parties acknowledge major holidays and always lend a fun, celebratory feel.
There are myriad sections without references. At other times the authors reference secondary sources (in discussing toilet training they note that "Pediatrician Lindy Woodard believes that a child can and should be trained by thirty months; in her professional experience, children who are trained at an older age have more problems learning to use the toilet." p. 168). Often the subject of a section would lack focus and context, such as p. 209 where the authors talk about "soul disorders" in reference to mental health. One assumes they are referencing the work of someone else, but it isn't cited or put into context. This leaves the reader to wonder why the authors would consider if "wisdom teeth extraction impacts our souls."
Otoacoustic emissions are clinically important because they are the basis of a simple, non-invasive test for hearing defects in newborn babies and in children who are too young to cooperate in conventional hearing tests. Many western countries now have national programmes for the universal hearing screening of newborn babies. Periodic early childhood hearing screenings program are also utilizing OAE technology. One excellent example has been demonstrated by the Early Childhood Hearing Outreach Initiative at the National Center for Hearing Assessment and Management (NCHAM) at Utah State University, which has helped hundreds of Early Head Start programs across the United States implement OAE screening and follow-up practices in those early childhood educational settings. The primary screening tool is a test for the presence of a click-evoked OAE. Otoacoustic emissions also assist in differential diagnosis of cochlear and higher level hearing losses (e.g., auditory neuropathy).
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.
