“…Sex differences in the structure and function of the auditory system have been widely reported [24–27]. Females showed significantly lower hearing thresholds than males, especially at higher frequencies (3000 Hz and above), where the sex difference was approximately 4–5 dB [28].…”

BackgroundThe aim of this study was to investigate the association between sex and speech-ABR in adults, and its relationship to sex hormone levels.Material/MethodsSpeech-ABR were elicited with the consonant-vowel syllable (/da/) in a total of 35 adults. Reproductive hormone levels were also measured.ResultsThe transient response of the speech-ABR (waves V, A, and O) in females show a shorter latency (waves V, A and O) and a larger amplitude (waves V and A) than in males (P<0.05), except for the amplitude of peak O (P>0.05). The sustained response of females exhibited a larger amplitude (wave F, P<0.05) and a shorter latency (wave D, E, and F, P<0.05) than in males, except for the amplitude of peak D and E (P>0.05). The latencies of speech-ABR were positively correlated with testosterone level (P<0.05), and were negatively correlated with estradiol (E2) levels (P<0.05), except for wave E (P>0.05). The E2 showed a positive correlation with the absolute value of amplitude of the speech-ABR (P < 0.05). On the contrary, total testosterone showed a negative correlation with the absolute value of amplitude the speech-ABR (P<0.05), except for wave D and wave O (P>0.05).ConclusionsSex differences in speech-ABR are significant in adults. The latencies and amplitude of the speech-ABR waves were correlated with the E2 concentration and testosterone level. The sex hormones likely affect speech encoding in the brainstem.

“…In different civilizations at different times, musical scales have in common the fact that the names of the notes can be repeated indefinitely within the physical limits of sound production. This circularity (also known as chromatic repetition) appears, in fact, to be universal, and seems to stem from a physiological basis of human perception (Braun & Chaloupa, 2005;Braun 2006) including that of neonates (Liu et al, 2009) and also that of rhesus monkeys (Wright et al, 2000). It was observed as early as the 1960s, in an anatomical study of a cat, that the auditory thalamus is organised in stacked layers or laminae.…”

Phonetics - the study and classification of speech sounds - is a major sub-discipline of linguistics. Bringing together a team of internationally renowned phoneticians, this handbook provides comprehensive coverage of the most recent, cutting-edge work in the field, and focuses on the most widely-debated contemporary issues. Chapters are divided into five thematic areas: segmental production, prosodic production, measuring speech, audition and perception, and applications of phonetics. Each chapter presents an historical overview of the area, along with critical issues, current research and advice on the best practice for teaching phonetics to undergraduates. It brings together global perspectives, and includes examples from a wide range of languages, allowing readers to extend their knowledge beyond English. By providing both state-of-the-art research information, and an appreciation of how it can be shared with students, this handbook is essential both for academic phoneticians, and anyone with an interest in this exciting, rapidly developing field.
