Summary
Hearing aids (HAs) improve speechreading skills in young adults with hearing impairment in China. Longer HA use correlates with better accuracy, challenging theories of visual dependence.
Area of Science:
- Audiology
- Speech and Hearing Sciences
- Ophthalmology
Background:
- Hearing impairment affects communication.
- Speechreading (lipreading) is a key skill for individuals with hearing impairment.
- The impact of hearing aids on speechreading is not fully understood.
Purpose of the Study:
- To investigate the effect of hearing aids (HAs) on speechreading performance in young adults with hearing impairment in China.
- To compare speechreading accuracy and speed between HA users and non-users.
- To explore the relationship between the duration of HA use and speechreading ability.
Main Methods:
- Sixty-seven young adults with hearing impairment using HAs and 78 without HAs participated.
- Participants completed newly developed Chinese speechreading tests at word, phrase, and sentence levels.
- Speechreading accuracy and speed were measured.
Main Results:
- Hearing aid users demonstrated significantly higher speechreading accuracy across all linguistic levels compared to non-users.
- Speechreading accuracy was highest for phrases, and speed was slowest for sentences in both groups.
- A positive correlation was found between the duration of HA use and speechreading accuracy.
Conclusions:
- Young hearing aid users in China exhibit superior speechreading performance compared to non-users.
- These findings contradict the perceptual dependence hypothesis.
- Hearing aids enhance, rather than diminish, reliance on auditory cues, supporting their role in auditory rehabilitation.

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.

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

01:16Bioavailability Enhancement: Drug Solubility Enhancement
251
Body:Bioavailability is a critical factor in determining a drug's effectiveness. It refers to the proportion of a drug that enters the circulation when introduced into the body and is, as a result, able to have an active effect. Enhancing bioavailability is essential for drugs with poor solubility, as it can significantly impact their therapeutic efficacy. Various methods are employed to increase the solubility of drugs, thereby enhancing their bioavailability.Micronization and nanonization are...

01:27Bioavailability Enhancement: Drug Permeability Enhancement
195
Body:After oral administration, poor permeability often limits the rate at which drugs are absorbed through the intestinal epithelium. Enhancing drug permeability is crucial for effective therapy, and several strategies have been developed to overcome this challenge.One effective strategy involves the use of lipid-based formulations. These formulations enhance dissolution and solubility, targeting physiological mechanisms to increase drug absorption. This includes stimulating bile salt...

205
Body:Improving a drug's stability in the gastrointestinal (GI) tract is paramount for enhancing its bioavailability and therapeutic effectiveness. Various strategies are employed to protect the drug from the harsh gastric milieu and to ensure its release and absorption at the desired site within the GI tract.Polymer coatings are one such method used to shield drugs from the stomach's acidic environment. By preventing premature drug release, these coatings improve the bioavailability of unstable...

01:27Exercise and Muscle Performance
2.3K
Exercise induces a range of adaptations in muscle tissue, depending on the type and duration of activity. Such physical training can be broadly categorized into two types: endurance exercises and resistance exercises.
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
