Autophonic loudness perception in Parkinson's disease [PDF]
Journal of the Acoustical Society of America, 2016 The relationship between the intensity and loudness of self-generated (autophonic) speech remains invariant despite changes in auditory feedback, indicating that non-auditory processes contribute to this form of perception. The aim of the current study was to determine if the speech perception deficit associated with Parkinson's disease may be linked ...

Manual Gestures Modulate Early Neural Responses in Loudness Perception [PDF]
Frontiers in Neuroscience, 2021 How different sensory modalities interact to shape perception is a fundamental question in cognitive neuroscience. Previous studies in audiovisual interaction have focused on abstract levels such as categorical representation (e.g., McGurk effect). It is

Loudness perception deficits during altered and absent auditory feedback in Parkinson’s disease [PDF]
Frontiers in Human NeurosciencePatients with Parkinson’s disease (PD) present with speech difficulties including abnormal speech intensity regulation. It is possible that the neural circuitry in speech may be unique and more complex compared to the other major motor symptoms.

Perception of loudness is influenced by emotion. [PDF]
PLoS ONE, 2012 Loudness perception is thought to be a modular system that is unaffected by other brain systems. We tested the hypothesis that loudness perception can be influenced by negative affect using a conditioning paradigm, where some auditory stimuli were paired

Effect of personality traits on sensitivity, annoyance and loudness perception of low- and high-frequency noise [PDF]
Journal of Low Frequency Noise, Vibration and Active Control, 2021 This paper presents investigations into a comparative assessment of the effects of low- and high-frequency noise in relation to personality traits. The high- and low-frequency noises used are produced in the research laboratory using CoolEdit software ...

Loudness Perception of Pure Tones in Parkinson's Disease. [PDF]
J Speech Lang Hear Res, 2018 PurposeReduced intensity is a hallmark of speech production in Parkinson's disease (PD). Previous work has examined the perception of intensity in PD to explain these speech deficits. This study reports loudness ratings of pure tones by individuals with PD and controls, all with normal thesholds for older adults.MethodTwenty individuals with PD and 23 ...

Cortical PV interneurons regulate loudness perception and sustainably reverse loudness hypersensitivity. [PDF]
NeuronParvalbumin-expressing inhibitory neurons (PVNs) stabilize cortical network activity, generate gamma rhythms, and regulate experience-dependent plasticity. We found that PVNs act like a volume knob in the mouse auditory cortex (ACtx), bi-directionally adjusting neural and perceptual sensitivity to sound level over a 20 dB range.

Characterizing Perception of Impulse Sounds Through Subjective Ratings and Pupillometric Responses [PDF]
Trends in HearingImpulse sounds such as clinking dishes or slamming objects are often perceived as particularly intense or uncomfortable, yet their perceptual characterization remains insufficiently understood.

Estimated cochlear neural degeneration is associated with loudness hypersensitivity in individuals with normal audiograms [PDF]
JASA Express Letters, 2022 In animal models, cochlear neural degeneration (CND) is associated with excess central gain and hyperacusis, but a compelling link between reduced cochlear neural inputs and heightened loudness perception in humans remains elusive.
