Auditory Perception

Auditory Perception

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...

Perception of Sound Waves

Perception of Sound Waves

The human ear is not equally sensitive to all frequencies in the audible range. It may perceive sound waves with the same pressure but different frequencies as having different loudness. Moreover, the perception of sound waves depends on the health of an individual's ears, which decays with age. The health of one's ears may also be affected by regular exposure to loud noises.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same frequency...

Perceiving Loudness, Pitch, and Location

Perceiving Loudness, Pitch, and Location

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 identifying...

Relative Frequency Histogram

Relative Frequency Histogram

The relative frequency depicts the proportion of data points that have each value. The frequency tells the number of data points that have each value. Like the histogram, a relative frequency histogram also has the same shape with a horizontal scale (the x-axis), but the vertical scale (the y-axis) is marked with relative frequencies (percentages of the whole) instead of actual frequencies. A relative frequency histogram is a graphical representation of a frequency distribution where the...

Time-Series Graph

Time-Series Graph

A time-series graph is a line graph with repeated measurements taken at successive intervals of time. It is also called a time series chart. To construct a time-series graph, one must look at both pieces of a paired data set. The horizontal axis is used to plot the time increments, and the vertical axis is used to plot the values of the variable that one is measuring. By using the axes in this way, each point on the graph will correspond to time and a measured quantity. The points on the graph...

Bode Plots

Bode Plots

Bode plots are graphical tools that use logarithmic scales for frequency on the x-axis and gain in decibels on the y-axis. This logarithmic method allows a wide range of frequencies to be compactly displayed, enabling the analysis of component effects on circuit behavior across a broad frequency spectrum.
A network function represents the ratio of a system's output to its input, with the magnitude and phase angle derived from the complex network function. The decibel logarithmic gain is...

Area of Science:

Otolaryngology
Audiology
Medical Imaging

Background:

Pure-tone audiometry generates threshold values often presented in multi-line plots.
Current methods for analyzing hearing data, like air-bone gap and pure-tone average, simplify statistical handling.
Visualizing longitudinal hearing data, especially for otosclerosis, presents challenges in tracking changes and event impacts.

Purpose of the Study:

To introduce the Sofia profile plot, a novel visualization tool for hearing threshold data.
To demonstrate the utility of the Sofia profile plot using cases of otosclerosis.
To provide a simple yet effective method for visually presenting pre- and postoperative hearing thresholds.

Main Methods:

The Sofia profile plot utilizes a two-dimensional space with a vertical time axis and a horizontal hearing level (decibels) axis.
Individual data points, including pure-tone average and other thresholds, are marked on the plot.
The plot allows for unambiguous marking of events such as operations, revisions, or tinnitus, with specific ear representation.

Main Results:

The Sofia profile plot offers a clear visual representation of multiple hearing threshold measurements over time.
It effectively displays pre- and postoperative hearing data for otosclerosis patients.
The plot facilitates the visual inspection of the impact of specific events on hearing levels.

Conclusions:

The Sofia profile plot is a valuable tool for visualizing hearing threshold changes in otosclerosis.
It enhances the understanding of treatment efficacy and the influence of audiological events on hearing.
This visualization method simplifies the interpretation of complex audiological data for otosclerotic patients.
