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.
Auditory Perception01:17

Auditory Perception

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 cochlea, a...
Language and Cognition01:27

Language and Cognition

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Area of Science:

  • Audiology
  • Hearing Technology
  • Cognitive Science

Background:

  • Wireless streaming technology (WT) transmits sound directly from mobile phones to hearing aids.
  • WT aims to improve the signal-to-noise ratio for hearing aid users.
  • The benefits of WT during phone use and associated demographics require further evaluation.

Purpose of the Study:

  • To investigate the benefits of bilateral wireless streaming in hearing aid users.
  • To identify predictive factors for WT benefits, particularly cognitive function.

Main Methods:

  • Eighteen adults with symmetrical, bilateral hearing loss were studied.
  • Sentence/word recognition and listening effort (self-reported) were assessed with WT "OFF" and "ON" in noisy environments.
  • Cognitive function was evaluated using the Montreal Cognitive Assessment (MoCA) score.

Main Results:

  • Wireless streaming significantly improved sentence/word recognition and reduced listening effort.
  • A significant positive correlation was found between MoCA scores and WT benefits (ρ=0.59, p=0.01).
  • Participants had a mean age of 57.3 years and a mean MoCA score of 27.0.

Conclusions:

  • Bilateral wireless streaming enhances auditory performance and reduces listening effort for hearing aid users during phone calls.
  • Cognitive function, as measured by MoCA, is positively associated with the benefits derived from wireless streaming technology.
