Perhaps the first sign that this book would be a let down were the typos throughout the pages (such as "hunbands" for husbands p 211, "sores" for scores p 104). The carelessness of the authors was reflected in the poor quality of the content and its presentation. This book lacked a coherent voice, and others have noted the contradictory statements found throughout its pages.
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.
I enjoyed reading Nourishing Traditions (NT) and have incorporated some of the information from that book into my family's diet. It also prompted me to delve into some areas of nutrition research that I hadn't read before NT. I expected this book to take a similar approach to child care (i.e. present qualitative and quantitative research, give an overview of historical trends, and present ideas from various cultures). I had high hopes for this book, since Sally Fallon was once again listed as an author, but after reading this book perhaps I should search for more from Mary Enig (the co-author of NT, but not on this book).
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.
In high school I was involved with sports (softball, basketball, track) was FFA vice president, and a member of the National Honor Society. After high school I received an athletic scholarship to play softball. While in college I started a physical education program at a local Lutheran Church School. The people and the children became family to me and I was offered a part time teaching assistant job working with the kindergarten class. During the summers of college I spent my time coaching softball to young girls. Over my four years of coaching we won four state titles, four regional titles, three Nationals appearances as well as an invitation to the Babe Ruth Little League World Series.
