Effects of age and hearing loss on the discrimination of amplitude and frequency modulation for 2-and 10-Hz rates

BCJ Moore, S Mariathasan, AP Sęk - Trends in Hearing, 2019 - journals.sagepub.com
Detection of frequency modulation (FM) with rate= 10 Hz may depend on conversion of FM
to amplitude modulation (AM) in the cochlea, while detection of 2-Hz FM may depend on the …

The roles of temporal envelope and fine structure information in auditory perception

BCJ Moore - Acoustical Science and Technology, 2019 - jstage.jst.go.jp

narrowband signals, each with a relatively slowly varying envelope (ENV) imposed on a …

Mechanisms of spectrotemporal modulation detection for normal-and hearing-impaired listeners

E Ponsot, L Varnet, N Wallaert, E Daoud… - Trends in …, 2021 - journals.sagepub.com
Spectrotemporal modulations (STM) are essential features of speech signals that make them
