Can a Remotely Delivered Auditory Training Program Improve Speech-in-Noise Understanding?
American Journal of Audiology
|December 10, 2015
Summary
This study found that a remote, internet-based auditory training program did not significantly improve speech-in-noise understanding compared to hearing aids alone. Compliance challenges may impact the effectiveness of such auditory training interventions.
Area of Science:
- Audiology
- Hearing Science
- Rehabilitation Technology
Background:
- Hearing aid users often struggle with understanding speech in noisy environments.
- Internet-based auditory training (AT) offers a potentially accessible alternative to traditional clinic-based programs.
Purpose of the Study:
- To evaluate the efficacy of a remotely delivered, internet-based AT program for improving speech-in-noise understanding in new hearing aid users.
- To determine if the duration of engagement with the AT program correlates with improvements in speech-in-noise understanding.
Main Methods:
- A randomized controlled trial involving 29 first-time hearing aid users.
- Participants were assigned to either an AT group (hearing aids + 3-week online AT) or a control group (hearing aids alone).
- Speech-in-noise tests were administered at baseline and post-intervention.
Main Results:
- Both groups showed improvements in speech-in-noise understanding, with no statistically significant difference between the AT and control groups.
- Participant engagement with the AT program was lower than prescribed.
- Time spent on the AT program positively influenced scores on the Words-in-Noise test but not the Hearing in Noise Test.
Conclusions:
- Remotely delivered, internet-based AT programs are appealing but face challenges in demonstrating consistent efficacy.
- Low compliance with AT programs is a significant factor affecting their effectiveness.
- Further research is needed to optimize compliance and efficacy of remote auditory interventions.

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...

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 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...
