Hearing

57.6K
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

Variability: Analysis01:11

Variability: Analysis

541
Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

Random Variables01:09

Random Variables

17.9K
A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...

Graphs of Equations in Two Variables

277
An equation with two variables, typically written in the form y = f(x) or Ax + By = C, describes a relationship between quantities represented by x and y. Each solution to such an equation is an ordered pair (x, y) that satisfies the equation when substituted. These pairs can be represented graphically to understand the variables' relationship visually.A common technique for constructing the graph of a two-variable equation is to create a value table. Begin by choosing several values for the...

Variables Affecting Phosphorescence and Fluorescence01:26

Variables Affecting Phosphorescence and Fluorescence

1.5K
Fluorescence and phosphorescence are essential phenomena in fields like analytical chemistry, biological imaging, and materials science, where they detect molecular properties and visualize cellular structures. Understanding the variables that influence these luminescent behaviors is crucial for maximizing accuracy and efficiency in their applications. These variables can broadly be grouped into chemical structure, solvent properties, and external conditions, each playing a distinct role in...

Cable Subjected to Its Own Weight01:13

Cable Subjected to Its Own Weight

815
Overhead power transmission lines rely on cables to carry electricity across large distances. To ensure the stability and functionality of these lines, it is crucial to understand the shape and tension experienced by the cables under the influence of their weight.
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...

Area of Science:

  • Audiology
  • Hearing Science
  • Telehealth Technology

Background:

  • The Home Hearing Test (HHT) is an automated pure-tone threshold test designed to increase access to hearing evaluations.
  • It supports home telehealth programs by providing an air conduction audiogram at five frequencies.

Purpose of the Study:

  • To determine the intrasubject variability of the Home Hearing Test (HHT).
  • Analysis focused on test and retest thresholds for 1000-Hz stimuli from two independent datasets.

Main Methods:

  • Two studies were conducted: one with 26 subjects at the VA and another with 100 subjects at NCRAR.
  • The Home Hearing Test (HHT) was used to obtain a five-frequency air conduction audiogram, with a 1000 Hz retest in both ears.
  • Six statistical measures of test-retest variability were reported, focusing on the 1000-Hz results.

Main Results:

  • Test and retest thresholds demonstrated high correlation (r ≥ 0.96) in both studies.
  • Test-retest differences were within ±5 dB for at least 92% of the time.
  • Standard deviations for absolute test-retest differences were ≤3.5 dB.

Conclusions:

  • Intrasubject variability in the Home Hearing Test (HHT) is comparable to manual audiologist testing.
  • The HHT shows potential for reliable home-based hearing assessments.
