Difference limens for frequency
WebJun 15, 2024 · The frequency difference limens deficits in α9KO mice were already present in P14 mice, only a few days after the onset of hearing (P12–P14; Song et al., 2006). This argues against the possibility that abnormal levels of sound-evoked auditory nerve activity caused by the dysfunctional MOC system caused the frequency … WebJan 21, 2009 · Frequency difference limens (FDLs) for pure tones between 200 and 6400 Hz and for the first, the second, or the eighth harmonic of an 800 Hz complex in four Mongolian gerbils (Meriones unguiculatus) were determined using a Go/NoGo-procedure.The 12 harmonics of the complex started either in sine phase or at a random …

Eighteen … WebAug 16, 2024 · At very high frequencies, fundamental-frequency difference limens (F0DLs) for five-component harmonic complex tones can be better than predicted by optimal integration of information, assuming performance is limited by noise at the peripheral level, but are in line with predictions based on more central sources of noise.
WebParticipants completed two psychoacoustic tasks: one determined frequency difference limens, and the other determined gap detection thresholds. Results showed impaired frequency discrimination at the highest standard frequency in the ASD group but no overall difference between groups. However, when groups were defined by auditory hyper ... WebHere we systematically examined frequency difference limens (FDLs), which measure the minimum discriminable frequency difference between two pure tones, in marmosets across most of their hearing range. Results show that marmosets' FDLs are comparable to other New World primates, with lowest values in the frequency range of ∼3.5-14 kHz.
WebFrequency difference limens ranged from 7% at 100 Hz, 17 dB sensation level (SL) to about 30% at 100, 300, and 600 Hz, 7 to 9 dB SL. Level difference limens ranged from 0.4 to 1.9 dB. Slopes of the equal-loudness contours were 0 at 100 Hz, about 6 dB/octave at 300 Hz, and leveled off to about 2 dB/octave above 600 Hz. WebAug 26, 1998 · Frequency discrimination was measured for a wide range of center frequencies (0.25–8 kHz) using three different tasks. In the first (difference limens for frequency, DLFs) subjects were required to indicate which of two successive tone pulses was higher in frequency. In the second (difference limens for change, DLCs), two …

Webpitch, and the frequency difference between the tones for which performance meets some criterion, for example, 75% correct, serves as the measure of the frequency-dif ference limen (DL). In the second method, the listener hears a target tone of given frequency and then adjusts the frequency ofa second tone to match the pitch of the target. top cherry hill nj restaurantsWebFrequency difference limens for 100 Hz electrical sinusoidal stimulation via a cochlear implant in the deafened ear were compared to those for 100 Hz sinusoidally amplitude-mod- ulated white noise (SAM noise) acoustic stimuli to the normal-hearing contralateral ear.
