Equilibrium and Balance01:15

Equilibrium and Balance

6.3K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

The Vestibular System01:29

The Vestibular System

43.4K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Anatomy of the Ear

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

The Cochlea01:13

The Cochlea

50.5K
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 Waves01:01

Perception of Sound Waves

5.4K
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...

Auditory Pathway01:15

Auditory Pathway

7.1K
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...

Summary

Young adults using earphones with extended high-frequency (EHF) hearing loss show early saccule damage. Cervical vestibular evoked myogenic potential (cVEMP) may detect this noise-induced cochlear damage.

Area of Science:

  • Audiology
  • Neuroscience
  • Otolaryngology

Background:

  • Unsafe earphone use can lead to hearing loss, with early shifts potentially occurring at extended high frequencies (EHFs) before conventional frequencies are affected.
  • Preliminary evidence suggests regular earphone use may also cause vestibular impairment.

Purpose of the Study:

  • To investigate vestibular function in young adults with normal conventional audiograms but varying EHF hearing status.
  • To determine if EHF hearing loss from earphone use is associated with early vestibular deficits.

Main Methods:

  • 131 young earphone users (12-25 years) were assessed for listening habits and audiogram thresholds at conventional and EHFs.
  • Vestibular function was evaluated using cervical vestibular evoked myogenic potential (cVEMP), subjective visual vertical (SVV), and video Head Impulse Test (vHIT).
  • Results were compared between participants with and without EHF hearing loss.

Main Results:

  • 15.3% of participants exhibited EHF hearing loss despite normal conventional audiograms.
  • Longer daily earphone usage duration was significantly associated with EHF loss (P=.008).
  • A significant reduction in cVEMP amplitude was observed in those with EHF loss (P<.001), indicating potential saccule damage.

Conclusions:

  • Earphone users with EHF loss may experience concurrent early saccule damage.
  • Cervical vestibular evoked myogenic potential (cVEMP) shows promise as a tool for detecting early noise-induced cochlear damage.
  • Further large-scale cohort studies are needed to validate cVEMP's utility.
