Hearing

58.7K
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

1.5K
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...

Perception of Sound Waves

6.0K
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...

Area of Science:

  • Gerontology
  • Audiology
  • Digital Health

Background:

  • Sensorineural hearing loss (SNH L) is prevalent in older adults, impacting speech perception.
  • Traditional auditory training can be time-consuming and require significant supervision.
  • Mobile health (mHealth) offers a potential platform for accessible and scalable interventions.

Purpose of the Study:

  • To develop a mobile-based auditory training program.
  • To evaluate the efficacy of this program for older adults with moderate-to-severe SNHL.

Main Methods:

  • Twenty older adults with hearing loss were randomized into a training group (TG) or a non-training control group (NTG).
  • The TG underwent 4 weeks of mobile auditory training (Korean nonsense syllables); the NTG received traditional training.
  • Speech perception was assessed using vowel, consonant, and sentence tests before and after the intervention.

Main Results:

  • The TG showed significant improvements in consonant and sentence recognition compared to the NTG.
  • Speech perception gains in the TG were maintained two weeks after training completion.
  • Vowel recognition scores did not significantly change in either group post-training.

Conclusions:

  • Mobile auditory training is an effective and cost-efficient method for improving speech understanding in older adults with hearing loss.
  • The program requires minimal supervision, making it a practical intervention.
  • Further research could explore optimizing training parameters for different speech components.
