Speech Perception in Classroom Acoustics by Children With Cochlear Implants and With Typical Hearing
American Journal of Audiology
|June 1, 2016
Summary
Children with cochlear implants benefit from reduced reverberation time (RT) to 0.3 seconds, supporting acoustic standards for learning spaces. Speech perception testing in sound booths may overestimate real-world listening abilities for these children.
Area of Science:
- Audiology
- Acoustics
- Speech-language pathology
Background:
- Reverberation time (RT) significantly impacts speech perception, especially for children with hearing impairments.
- Understanding optimal acoustic conditions in learning environments is crucial for children's educational success.
Purpose of the Study:
- To measure speech perception in children with cochlear implants (CIs) and typical hearing across varying reverberation times (RTs) and speech-to-noise ratios (SNRs).
- To evaluate the effectiveness of different acoustic conditions in classroom and sound booth settings.
Main Methods:
- Participants (children with CIs and typical hearing) were tested in classroom RTs of 0.3, 0.6, and 0.9 seconds with a 21-dB SNR range.
- Speech perception was assessed using the Bamford-Kowal-Bench Speech-in-Noise Test, with supplementary percent-correct analyses.
- A subset of participants also completed testing in a low-reverberant audiological sound booth.
Main Results:
- Reducing RT from 0.9 to 0.6 seconds improved speech perception for both groups.
- Further RT reduction to 0.3 seconds benefited children with CIs but not those with typical hearing.
- Children with CIs scored significantly higher in the sound booth compared to classroom settings.
Conclusions:
- Classroom RT standards of 0.6 seconds for typical hearing and 0.3 seconds for auditory impairments are supported.
- Sound booth testing may overestimate the classroom listening performance of children with CIs.
- Acoustic standards are vital for creating effective learning environments for children with hearing loss.

1.3K
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...

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...

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.

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.

01:13The Cochlea
52.4K
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.

01:15Auditory Pathway
8.6K
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.
