Human Envelope Following Responses to Amplitude Modulation: Effects of Aging and Modulation Depth.
OBJECTIVE To record envelope following responses (EFRs) to monaural amplitude-modulated broadband noise carriers in which amplitude modulation (AM) depth was slowly changed over time and to compare these objective electrophysiological measures to subjective behavioral thresholds in young normal hearing and older subjects. DESIGN PARTICIPANTS three groups of subjects included a young normal...
متن کاملDemonstrating the temporal modulation transfer function.
A 120-frame movie, which can be downloaded from specified web sites, allows an observer to see the qualitative form of his or her temporal modulation transfer function. Results collected from two of the authors are presented.
متن کاملAcoustic change responses to amplitude modulation: a method to quantify cortical temporal processing and hemispheric asymmetry
OBJECTIVE Sound modulation is a critical temporal cue for the perception of speech and environmental sounds. To examine auditory cortical responses to sound modulation, we developed an acoustic change stimulus involving amplitude modulation (AM) of ongoing noise. The AM transitions in this stimulus evoked an acoustic change complex (ACC) that was examined parametrically in terms of rate and dep...
متن کامل[Temporal modulation transfer function in normal-tension glaucoma patients].
In an attempt to detect patients in an early stage of glaucoma, a new screening test, the Flicker System, by which temporal modulation transfer function is evaluated, was performed in 64 normal-tension glaucoma patients and 65 normal eyes. The early stage of glaucoma, i.e., stage 0-1 of Aulhorn-Greve's classification, showed a significant decrease of the modulation in the range from 20 to 45 Hz...
متن کاملExperimental comparison of turbulence modulation transfer function and aerosol modulation transfer function through the open atmosphere
Although turbulence is usually considered to be the primary cause of image blur, simultaneous and independent measurements of overall atmospheric modulation transfer function (MTF) and turbulence MTF over fairly long horizontal paths at 15-m average elevation indicate that, even at midday, aerosol MTF deriving from forward scatter is usually more dominant than turbulence MTF. Three different ex...
