Insights

Children with phonological disorders show no alterations in the medial olivocochlear system. Transient evoked otoacoustic emissions (TEOAE) suppression was similar between children with and without these speech sound disorder.

Area of Science:

  • Pediatric Audiology
  • Speech-Language Pathology
  • Neuroscience

Background:

  • Phonological disorders impact speech sound development in children.
  • The medial olivocochlear system plays a role in auditory processing.
  • Understanding auditory system function in phonological disorders is crucial.

Purpose of the Study:

  • To investigate potential alterations in the medial olivocochlear system in children with phonological disorders.
  • To compare auditory function between children with and without phonological disorders.

Main Methods:

  • Prospective cross-sectional study of 19 children (4-7 years old).
  • Auditory assessment included otoscopy, pure tone audiometry, and tympanometry.
  • Transient evoked otoacoustic emissions (TEOAE) with and without contralateral noise evaluated medial olivocochlear function.

Main Results:

  • No significant differences in TEOAE suppression occurrence or values were found between groups.
  • TEOAE suppression was consistent across tested frequencies (1-4 kHz) in both control and study groups.

Conclusions:

  • Children with phonological disorders do not exhibit alterations in their medial olivocochlear system function.
  • Transient evoked otoacoustic emissions (TEOAE) suppression is not affected by phonological disorders.

The Cochlea01:13

The Cochlea

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
Hearing01:31

Hearing

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.
Auditory Pathway01:15

Auditory Pathway

Auditory pathways constitute the complex neural circuits responsible for transmitting and interpreting auditory information from the peripheral auditory system to the brain. Sound waves are initially captured by the outer ear, funneled through the ear canal, and reach the tympanic membrane (eardrum). These vibrations are transmitted via the middle ear's ossicles to the inner ear's cochlea.
When viewed cross-sectionally, the cochlea reveals the scala vestibuli and scala tympani flanking the...
Auditory Perception01:17

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...
The Auditory Ossicles01:11

The Auditory Ossicles

The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...
Higher Mental Functions of the Brain: Language01:10

Higher Mental Functions of the Brain: Language

Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
