The paper estimates modulation statistics of natural soundscapes using acoustic samples from different habitats and relates them to environmental factors and biodiversity.

This study assesses human ability to identify and discriminate time of day from natural soundscapes, finding poor identification but significant discrimination, with decisions based on gross spectral cues.

This study investigates how normal-hearing and hearing-impaired listeners detect spectrotemporal modulations using a psychophysical reverse-correlation framework and finds comparable non-linear processing strategies with differences in temporal modulation tuning.

The paper identifies target-specific and masker-specific neurons in the auditory system that operate under noise conditions, showing a distributed network for auditory perception.

The paper investigates how cortical and subcortical neurons discriminate sounds in noise, finding that subcortical structures perform better than cortical ones, primarily due to the distortion of slow amplitude modulation cues.

This paper develops a low-parameter model to study firing regularity in chopper cells of the ventral cochlear nucleus, showing multiple mechanisms can explain their behavior and predicting effects of synaptopathy.
