Auditory Pathway01:15

Auditory Pathway

5.4K
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...

Hearing01:31

Hearing

52.4K
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.

Anatomy of the Ear01:16

Anatomy of the Ear

8.4K
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...

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

220
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...

Auditory Perception01:17

Auditory Perception

343
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...

The Cochlea01:13

The Cochlea

45.1K
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.

Area of Science:

  • Explores the intersection of affective science and audiology.
  • Highlights the bidirectional relationship between auditory and affective systems.

Background:

  • Affective phenomena are increasingly recognized in health sciences, including audiology.
  • Currently, audiology often views affective phenomena solely as a consequence of hearing status.

Purpose of the Study:

  • To review the reciprocal relationship between auditory and affective systems.
  • To propose that audiology challenges may be affect-related and solvable through affective science.
  • To introduce affective science resources for audiology professionals.

Main Methods:

  • Review of anatomical and functional connections between auditory and affective systems.
  • Analysis of four practical audiology examples: public campaigns, intervention uptake, evaluation, and tinnitus.
  • Identification of resources from affective science for audiology integration.

Main Results:

  • Evidence supports a reciprocal affect-hearing relationship.
  • Key audiology challenges in public campaigns, intervention uptake, evaluation, and tinnitus are likely affect-related.
