Auditory Perception01:17

Auditory Perception

409
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...

Perceiving Loudness, Pitch, and Location01:21

Perceiving Loudness, Pitch, and Location

314
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...

Perception of Sound Waves01:01

Perception of Sound Waves

4.5K
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...

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.

Air-entraining Agents01:27

Air-entraining Agents

101
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Area of Science:

  • Auditory Neuroscience
  • Speech Perception Research
  • Cognitive Training

Background:

  • Speech perception in noise (SPIN) is a complex auditory-cognitive task.
  • Deficits in pitch perception, temporal/intensity cue processing, or cognitive function impede SPIN.
  • Physiological sound representations can be improved through targeted exercises.

Purpose of the Study:

  • To review and categorize various training methods for improving speech perception in noise.
  • To discuss the efficacy of both bottom-up and top-down training approaches.
  • To provide a framework for selecting appropriate training interventions based on identified deficits.

Main Methods:

  • Categorization of training methods into bottom-up (pitch, spatial, temporal, phoneme) and top-down (cognitive/memory).
  • Inclusion of music training's dual impact on both bottom-up and top-down processes.
  • Discussion of specific speech training in noise protocols.

Main Results:

  • Bottom-up training methods, including pitch, spatial, temporal, and phoneme training, show effectiveness.
  • Top-down cognitive training, particularly functional memory exercises, can enhance SPIN.
  • Music training positively influences both auditory processing and cognitive aspects relevant to SPIN.

Conclusions:

  • Various training methods, encompassing auditory and cognitive exercises, can significantly improve speech perception in noise.
  • Identifying specific underlying deficits is crucial for selecting the most effective training strategy.
  • A personalized approach combining different training modalities may offer optimal outcomes for individuals with SPIN challenges.
