A speculation about the parallel ear asymmetries and sex differences in hearing sensitivity and otoacoustic emissions

Deficiência auditiva referida por idosos no Município de São Paulo, Brasil: prevalência e fatores associados (Estudo SABE, 2006)

“…Mesmo que as estruturas do sistema auditivo pareçam semelhantes para homens e mulheres ao nascimento, pequenas diferenças foram verificadas em resultados de exames de emissões otoacústicas e potenciais evocados de tronco encefálico. Consequentemente, diferenças hormonais e metabólicas também devem ser consideradas nessas análises 44 .…”

Relationship of the differences in perceived loudness of sound and the optimum listening level between males and females

“…The previous studies revealed less efferent inhibition [6] and higher sensitivity of hearing in females than in males [7]. In addition, Torre reported that male participants required a higher sound pressure level to perceive the loudness of reproduced sounds as loud than female participants [8].…”

Prenatal sex hormone effects on child and adult sex-typed behavior: methods and findings

“…There are some interesting properties of OAEs that make them good candidates for understanding behavioral effects of hormones. OAEs vary across ears: there are more SOAEs and stronger CEOAEs in right than left ears [203,204]. OAEs are stable from an early age [205,206], although they can be influenced by postnatal events, including, e.g.…”
