Objectives:
Normative data are important in the clinical setting of Speech and Language Pathology. The purpose of this study was to develop a normative reference dataset of voice range profiles from young females.
Study Design:
Descriptive study including a prospective collection of voice range profile data.
Methods:
Voice range profile recordings from 39 females with healthy voices aged 18 to 28 years were conducted. Seven voice range profile variables were analyzed: minimum and maximum fundamental frequency and intensity, semitone and intensity ranges, and voice range profile area. Descriptive statistical methods were applied.
Results:
An age-specific voice range profile normative dataset was established. The mean values and standard deviations were as follows: semitone range 34.7 ± 3.9 ST, minimum fundamental frequency 143.6 ± 21.7 hertz, maximum fundamental frequency 1063.5 ± 160 hertz, intensity range 65.6 ± 5.0 dB, minimum intensity 43.2 ± 2.5 dB SPL, maximum SPL 108.9 ± 5.1 dB SPL, and voice range profile area 1346 ± 222 cells.
Conclusion:
A normative dataset usable for optimization of future voice assessments has been established. It may especially benefit evaluation and treatment planning for younger females suffering from vocal fold nodules.

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,...

Breath Sounds
Breath sounds are categorized into vesicular, bronchovesicular, and bronchial.
00:53Sound Intensity Level
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...

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...
01:29Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
