Hair Cells01:22

Hair Cells

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.
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.
Biological Effects of Radiation02:59

Biological Effects of Radiation

All radioactive nuclides emit high-energy particles or electromagnetic waves. When this radiation encounters living cells, it can cause heating, break chemical bonds, or ionize molecules. The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, α and β particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. When these particles strike and penetrate matter, they produce ions...
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...
Anatomy of the Ear01:16

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...
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...

This summary is machine-generated.

High-frequency pulsed electromagnetic fields (PEMF) from mobile phones did not measurably affect auditory function. Otoacoustic emissions testing showed no significant changes in outer hair cell function during phone use.

Area of Science:

  • Audiology
  • Electromagnetic field effects
  • Otoacoustic emissions

Background:

  • Mobile telephones emit pulsed electromagnetic fields (PEMF).
  • PEMF has known biological effects, with potential impacts on the auditory system.
  • Otoacoustic emissions (OAEs) reflect the functional status of the auditory system's outer hair cells.

Purpose of the Study:

  • To investigate whether PEMF radiation from mobile phones causes measurable changes in Otoacoustic emissions.
  • To assess the immediate effects of mobile phone use on the auditory system's outer hair cell function.

Main Methods:

  • 12 healthy volunteers with normal hearing underwent pure tone audiometry.
  • Otoacoustic emissions were recorded before, during, and after exposure to a mobile phone placed on the mastoid process.
  • Measurements were taken during both receive and transmit modes of the mobile phone.

Main Results:

  • No alterations in the Otoacoustic emission trace signature were observed during mobile phone use.
  • Statistical analysis revealed no significant changes in the measured OAE parameters.
  • This suggests PEMF exposure from handheld mobile phones did not impact outer hair cell function.

Conclusions:

  • Handheld mobile telephones emitting PEMF do not produce measurable effects on outer hair cell function during typical usage.
  • Current mobile phone technology, under the tested conditions, appears safe concerning immediate auditory outer hair cell function.
