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.
The benefits of high quality early learning experiences for children appeal to both early childhood programs and families. By participating in the Qualistar Rating™ programs receive a detailed Quality Performance Profile© (QPP) that includes strengths and areas for improvement specific to their program and classrooms. Families benefit by accessing the program’s Quality Rating Report and by gaining an understanding of the components contributing to quality early learning experiences. This helps parents make more informed choices on the type of care they would like for their child.
In 2009, Stephen Beeby of The University of Southampton led research into utilizing otoacoustic emissions for biometric identification. Devices equipped with a microphone could detect these subsonic emissions and potentially identify an individual, thereby providing access to the device, without the need of a traditional password. It is speculated, however, that colds, medication, trimming one's ear hair, or recording and playing back a signal to the microphone could subvert the identification process.
If you pay taxes to the District you are entitled to reduced rates at any District facility. A photo ID can be acquired at the Trails Recreation Center for $5.00/person or $10.00/family and is valid for 3 years. A current Arapahoe County tax statement, a valid driver’s license or mail addressed to you from your utility or phone company is what we will accept to show proof of residency. Resident’s must present a current District ID card to receive District rates. Residents and non-residents purchasing a Trails pass will receive an ID card free with this purchase. Lost, stolen or damaged cards can be replaced for $5.00.
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.
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."
Although I anticipated the publishing of this book with excitement, I cannot recommend "The Nourishing Traditions Book of Baby and Child Care". Thank you for taking the time to read this review, and thank you for not clicking "unhelpful" simply because you disagree with my view. NT is a groundbreaking book, and I sincerely hope this book does not tarnish its reputation.
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.
