Spontaneous Otoacoustic Emissions

Paper Summary:

This paper presents a research proposal to study gender and postural changes and their effects on spontaneous otoacoustic emissions. To explore this subject one must first understand what spontaneous otoacoustic emissions (SOAEs) are, what role gender has on SOAEs and what the implications are of such roles and studies. Further, the paper explains that this research will provide information on the role posture has related to SOAEs and its implications. To achieve this the researcher asks the following questions: (1) what are SOAEs and what role does gender have on SOAEs (2) what role does posture have on SOAEs and (3) what implications do these findings provide? .

From the Paper:

"Bilger, Matthies & Hammel (1990) conducted an earlier study of spontaneous otoacoustic emissions to better understand and delineate their effects or purpose. Using information and data gathered from three studies conducted in the early to mid 1980s, the researchers discovered female subjects experienced a much greater prevalence of SOAEs than males (P(S|F) = .533 females). The researchers also noted evidence from previous studies suggested regardless of gender SOAEs were more prevalent in participants right ears than in the left ears."
