Pitch , loudness and frequency selectivity in low - frequency hearing loss
Patients with Ménière's disease and cochlear hydrops show fluctuating low-frequencyhearing loss (FLFHL). At present these changes are followed as patients' subjectivereports and occasional measurements. Consecutive long-term measurements shouldprovide more comprehensive information on the hearing fluctuations than theoccasional audiogram used today and constitute an approach...
متن کاملComparison of frequency discrimination thresholds for complex and single tones in chinchillas.
Frequency discrimination thresholds were measured from five chinchillas for harmonic tone complexes having a fundamental frequency of 250 Hz. Stimuli consisted of the fundamental frequency and the second through 10th harmonics with individual components added in either cosine phase or random phase. In general, thresholds were independent of overall level for sound levels between 47 and 77 dB SP...
متن کاملTheme 1: Masking and Frequency Selectivity
The main theme in this topic area is to highlight the different approaches taken by hearing scientists to characterize the human auditory system. If our auditory system behaves like a linear time-invariant system, whereby the response of the cochlear filter is completely described by the relationship between its inputs and its outputs, such characterization would be a trivial matter. However, o...
متن کاملWaveform Selectivity at the Same Frequency
Electromagnetic properties depend on the composition of materials, i.e. either angstrom scales of molecules or, for metamaterials, subwavelength periodic structures. Each material behaves differently in accordance with the frequency of an incoming electromagnetic wave due to the frequency dispersion or the resonance of the periodic structures. This indicates that if the frequency is fixed, the ...
متن کاملSpatial frequency selectivity of cells in macaque visual cortex.
We measured the spatial frequency contrast sensitivity of cells in the primate striate cortex at two different eccentricities to provide quantitative statistics from a large population of cells. Distributions of the peak frequencies and bandwidths are presented and examined in relationship to (a) each other, (b) absolute contrast sensitivity, (c) orientation tuning, (d)retinal eccentricity, and...
