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.
Unrenewable Cells00:50

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...
Perception of Sound Waves01:01

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...
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.
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...

Summary

Nonorganic hearing loss in children, often linked to emotional issues, presents as hearing impairment without physical auditory system damage. Diagnosis involves specific tests and a thorough personal and psychological history for effective management.

Area of Science:

  • Pediatric Audiology
  • Child Psychology
  • Neuroscience

Context:

  • Nonorganic (functional) hearing loss is a childhood condition lacking detectable auditory pathology.
  • Characterized by a discrepancy between pure-tone thresholds and speech discrimination.
  • Affects children, with a mean age of diagnosis at 11.3 years; girls are twice as likely as boys.

Purpose:

  • To review the characteristics, diagnosis, and management of nonorganic hearing loss in children.
  • To highlight the prevalence of emotional and school-related problems in affected children.
  • To discuss differential diagnoses and recommend diagnostic and prognostic approaches.

Summary:

  • Evaluated 85 publications, 27 reviews, and 4 textbook articles on nonorganic hearing loss.
  • Patient histories reveal a high incidence of emotional and school difficulties.
  • Brainstem audiometry is recommended for diagnosis, with differential considerations including auditory processing disorder and auditory neuropathy.

Impact:

  • Suggests a link between functional hearing loss and psychological factors in children.
  • Recommends comprehensive patient history, psychological assessment, and psychiatric referral.
  • Prognosis is influenced by the severity of personal and school problems, with the Austen-Lynch model as a potential prognostic tool.
