Effects of feedback01:24

Effects of feedback

669
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

233
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

401
The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...

Feedback control systems01:26

Feedback control systems

385
Feedback control systems are categorized in various ways based on their design, analysis, and signal types.
Linear feedback systems are theoretical models that simplify analysis and design. These systems operate under the principle that their output is directly proportional to their input within certain ranges. For instance, an amplifier in a control system behaves linearly as long as the input signal remains within a specific range. However, most physical systems exhibit inherent nonlinearity...

Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

3.5K
Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...

Summary
This summary is machine-generated.

Auditory feedback control for voice loudness, like pitch, changes with speaking tasks. Producing sentences shows larger and faster loudness responses than sustained vowels, indicating task-specific adjustments in auditory targets.

Area of Science:

  • Speech production and perception
  • Auditory feedback mechanisms
  • Vocal control

Background:

  • Auditory feedback is crucial for regulating voice fundamental frequency (fo).
  • fo control is task-dependent, with sentence production eliciting larger responses to pitch perturbations than sustained vowels.
  • This suggests auditory targets are scaled based on task precision requirements.

Purpose of the Study:

  • To investigate if auditory feedback control of vocal intensity (loudness) is also modulated by speaking task.
  • To compare vocal intensity responses to loudness perturbations during sentence versus sustained-vowel production.

Main Methods:

  • Twenty-five English speakers produced sentences and sustained vowels.
  • Participants heard their voice loudness perturbed (+/- 3 or 6 dB SPL for 200 ms).
  • Vocal intensity responses and peak latencies were measured.

Main Results:

  • Vocal intensity response magnitudes were significantly larger in sentence production (mean: 1.96 dB) than in vowel production (mean: 0.89 dB).
  • Response magnitudes varied with perturbation size differently for upward and downward perturbations in sentence production.
  • Peak response latencies were shorter in sentence production (mean: 184.94 ms) compared to vowel production (mean: 214.92 ms).

Conclusions:

  • Auditory feedback control of vocal intensity is modulated by speaking task, similar to pitch control.
  • Auditory targets for loudness are scaled according to the precision demands of the specific speaking task.
