Summary
A significant number of children (37.14%) have dysphonia, often characterized by breathy or rough voice quality and negative self-perception. Acoustic measures were also altered in these children.
Area of Science:
- Pediatric Voice Disorders
- Speech-Language Pathology
- Otolaryngology
Context:
- Dysphonia prevalence in children is not well-established.
- Understanding the relationship between objective voice measures and subjective self-perception is crucial for diagnosis and intervention.
- Childhood voice disorders can impact social and academic development.
Purpose:
- To determine the prevalence of dysphonia in children aged 6-10 years.
- To compare auditory-perceptive, acoustic, and vocal self-perception data between dysphonic and non-dysphonic children.
- To investigate the correlation between objective voice findings and children's self-assessment of their voice.
Summary:
- The study found a 37.14% occurrence of dysphonia in 70 children (ages 6-10).
- Dysphonic children most frequently presented with breathy and/or rough voice qualities.
- Acoustic analysis revealed higher frequency and amplitude perturbation quotient and lower harmonic-to-noise ratio in dysphonic children. Negative self-perception was more common in dysphonic children, though acoustic measures did not differ based on self-perception.
- Auditory-perceptive analysis identified breathiness and roughness as common vocal deviations.
Impact:
- This research highlights a substantial prevalence of childhood dysphonia, emphasizing the need for early identification and intervention.
- Findings underscore the connection between objective voice characteristics, perceptual voice quality, and negative self-perception in dysphonic children.
- The study provides valuable data for clinicians and researchers in pediatric voice disorders, informing diagnostic and therapeutic strategies.

01:17Auditory 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...
01:01Perception 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...

01:20Social Foundations of Self II: The Generalized Other
According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group effort.
01:21Perceiving 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...

01:31Hearing
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.
01:30Social Foundations of Self III: Self-Evaluation
Self-evaluation is the process by which individuals assess their abilities, behaviors, and characteristics based on feedback from others. Charles H. Cooley observed that a person’s self-perception is primarily influenced by how others see and judge them. He suggested that individuals form their identities based on their interpretations of others' reactions. As a result, social interactions play a crucial role in shaping self-esteem and personal identity. These external evaluations often blend...
