Quantitative Assessment of Cortical Auditory-tactile Processing in Children with Disabilities
Published on: January 29, 2014
Summary
Tinnitus is common in deaf children, affecting 78 out of 158 surveyed. Many experienced intermittent tinnitus, impacting their hearing and speech, with some reporting associated symptoms like headaches.
Area of Science:
- Audiology
- Pediatric Health
- Otolaryngology
Background:
- Tinnitus is a prevalent auditory symptom.
- Understanding tinnitus in deaf children is crucial for their development.
Purpose of the Study:
- To investigate the prevalence and characteristics of tinnitus in deaf children.
- To identify factors associated with troublesome tinnitus in this population.
Main Methods:
- A survey was conducted among 158 deaf children aged secondary-school.
- Data collected included tinnitus presence, constancy, frequency, duration, loudness, and associated symptoms.
Main Results:
- 78 out of 158 children (49.4%) reported tinnitus.
- Tinnitus was predominantly intermittent (76 children).
- Reported impacts included reduced hearing ability, speech discrimination, and associated headaches or vertigo.
Conclusions:
- Tinnitus is a significant issue for a substantial portion of deaf children.
- The characteristics and associated symptoms of tinnitus in deaf children warrant further investigation and management strategies.

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.
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.
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...

Unrenewable Cells
In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...

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.

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...
