Summary
This review classifies biomechanical models of voice production, categorizing them by vocal fold, vocal tract, and airflow interactions. It offers insights into the current state of mathematical modeling in vocal physiology.
Area of Science:
- Biomechanics
- Physiology
- Acoustics
Background:
- Biomechanical modeling provides insights into unobservable physical phenomena in voice production.
- Understanding voice production requires analyzing aerodynamic, biomechanical, and acoustic interactions.
- Mathematical models are crucial for studying the physiological processes of human voice generation.
Approach:
- A systematic literature review was conducted using PubMed/Medline, SCOPUS, and IEEE Xplore databases.
- The PRISMA Statement protocol guided the selection of 53 relevant publications.
- A taxonomic classification of voice production models was developed and analyzed.
Key Points:
- Models were categorized into four groups: Source (Vocal folds), Filter (Vocal Tract), Source-Filter Interaction, and Airflow-Source Interaction.
- Bibliographic analysis tracked the evolution and publication trends within each model category.
- Term occurrence and frequency analysis provided insights into research focus.
Conclusions:
- The review synthesizes the state-of-the-art in mathematical modeling of voice production.
- It highlights the correlation between aerodynamic, biomechanical, and acoustic phenomena and vocal physiology.
- This work offers a comprehensive overview for researchers in biomechanical voice modeling.

01:21Larynx
3.1K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

01:09Clearance Models: Physiological Models
178
Drug clearance is a critical pharmacokinetic process involving the irreversible removal of drugs from the body through various organs over a specified time period. Physiological models are indispensable in determining organ-specific clearance, defined by the proportion of the drug eliminated per unit of time from the organ's blood volume.
The organ's clearance rate depends on the blood flow to the organ and the extraction ratio (E). The extraction ratio describes the organ's...

01:15Model Approaches for Pharmacokinetic Data: Physiological Models
168
Physiological models in pharmacokinetics are instrumental in understanding the distribution and elimination of drugs within the body. These models describe the drug concentration within target organs, influenced by factors such as drug uptake, tissue volume, and blood flow. Drug uptake is governed by the partition coefficient, which signifies the drug concentration ratio in tissue to that in the blood. The blood flow rate to a specific tissue is expressed as Qt, and the rate of change in tissue...

The Role of Accessory Muscles in the Respiratory System
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...

01:24Facial Feedback Hypothesis
377
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...

The respiratory system, fundamental to life, consists of complex structures responsible for gas exchange. The percussion assessment is critical to understanding this system's health and functionality. This non-invasive assessment technique allows healthcare providers to evaluate the density or aeration of the lungs, thereby identifying potential abnormalities.
