A Brownian energy depot model of the basilar membrane oscillation with a braking mechanism.

9 Jul 2009 High auditory sensitivity, sharp frequency selectivity, and spontaneous otoacoustic emissions are signatures of active amplification of the cochlea. The human ear can also detect very large amplitude sounds without being damaged, as long as the ... Read more...

Lateralization of stimuli with independent fine-structure and envelope-based temporal disparities.

27 Feb 2009 Psychoacoustic experiments were conducted to investigate the role and interaction of fine-structure and envelope-based interaural temporal disparities. A computational model for the lateralization of binaural stimuli, motivated by recent ... Read more...

Pitfalls in behavioral estimates of basilar-membrane compression in humans.

30 Dec 2008 Psychoacoustic estimates of basilar-membrane compression often compare on- and off-frequency forward masking. Such estimates involve assuming that the recovery from forward masking for a given signal frequency is independent of masker frequency. To ... Read more...

Technical information about 'Basilar Membrane'

Definition: A basement membrane in the cochlea that supports the hair cells of the ORGAN OF CORTI, consisting keratin-like fibrils. It stretches from the SPIRAL LAMINA to the basilar crest. The movement of fluid in the cochlea, induced by sound, causes displacement of the basilar membrane and subsequent stimulation of the attached hair cells which transform the mechanical signal into neural activity.
