Summary
Aging significantly decreases speech discrimination in patients with hearing loss. Higher pure-tone average and older age are key factors linked to reduced speech clarity in presbycusis.
Area of Science:
- Audiology
- Gerontology
- Speech Science
Background:
- Presbycusis, or age-related hearing loss, often involves decreased speech discrimination.
- Understanding factors contributing to this decline is crucial for effective management.
Purpose of the Study:
- To identify factors associated with reduced speech discrimination in patients with presbycusis.
- To determine the impact of aging on speech discrimination ability.
Main Methods:
- Retrospective analysis of medical records for patients over 40 years old.
- Inclusion of pure-tone audiometry, speech audiometry, and auditory brainstem response data.
- Correlation and multiple linear regression analyses to identify predictors of speech discrimination scores.
Main Results:
- 103 patients (120 ears) with a mean age of 65.8 years were analyzed.
- A significant negative correlation was found between speech discrimination scores and both age and pure-tone average.
- Pure-tone average and age were identified as significant predictors of lower speech discrimination scores.
Conclusions:
- Speech discrimination ability significantly declines with increasing age and pure-tone average in patients with hearing loss.
- Age and audiometric measures are critical factors influencing speech clarity in older adults.

2.3K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:30Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
