背景情况:
- 听力损失影响了全球5%以上的人口,构成了重大的公共卫生挑战.
- 由于不同的听力测量标准和方法,对听力损失的残疾确定在国际上有所不同.
- 获得康复服务取决于准确的听力损失残疾评估.
研究的目的:
- 审查有关全球听力测量值的现有文献,以确定听力障碍.
- 突出当前国际标准中的挑战和不一致性.
- 探索对标准化和公平指导方针的需求.
主要方法:
- 在PubMed,Embase和Web of Science进行了全面的文献搜索.
- 从2010年到现在以英语出版的专注于听力障碍标准的文章被包括在内.

Hearing
52.0K
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.

Criteria for Causality: Bradford Hill Criteria - II
287
The Bradford Hill criteria serve as guidelines for establishing causative links in epidemiological research. Beyond Strength, Consistency, Specificity, and Temporality, key criteria also include Biological Gradient, Plausibility, Coherence, Experiment, and Analogy. These principles assist scientists in assessing the likelihood of causation in complex biological contexts. Below is a summary of these concepts:

Perceiving Loudness, Pitch, and Location
205
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...

Intellectual Disability
49
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Auditory Perception
331
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...
