Summary
Low income is linked to adult-onset hearing loss. Most studies found this association, but more research is needed to understand the cause and effect relationship.
Area of Science:
- Public Health
- Epidemiology
- Social Determinants of Health
Background:
- Hearing loss is linked to negative health outcomes and lower socioeconomic status.
- A comprehensive review of the literature on the association between income and hearing loss is lacking.
Approach:
- A systematic literature search was performed across eight databases.
- Studies focusing on adult-onset hearing loss and income were included.
- The Newcastle-Ottawa Quality Assessment Scale was used to assess study bias.
Key Points:
- 46 articles were included in the qualitative synthesis.
- 41 of the 46 articles reported an association between income and hearing loss.
- A meta-analysis was not feasible due to study design heterogeneity.
Conclusions:
- Existing literature suggests a consistent association between income and adult-onset hearing loss.
- The current evidence is limited to cross-sectional studies, preventing determination of causality.
- Understanding the role of social determinants like income is crucial for hearing loss prevention and management.

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.

01:08Outliers and Influential Points
4.1K
An outlier is an observation of data that does not fit the rest of the data. It is sometimes called an extreme value. When you graph an outlier, it will appear not to fit the pattern of the graph. Some outliers are due to mistakes (for example, writing down 50 instead of 500), while others may indicate that something unusual is happening. Outliers are present far from the least squares line in the vertical direction. They have large "errors," where the "error" or residual is the...

2.3K
In humans, the photoreceptor cells of the eye and sensory hair cells of the ear lack stem cells. These cells are thus unrenewable and cannot be replaced when they are damaged or destroyed.
Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...

01:01Perception of Sound Waves
4.5K
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.
The pitch of a sound depends on the frequency and the pressure amplitude of the source. Two sounds of the same...

01:13The Cochlea
45.2K
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.

00:53Sound Intensity Level
4.2K
Humans perceive sound by hearing. The human ear helps sound waves reach the brain, which then interprets the waves and creates the perception of hearing. The loudness of the environment in which a person is located determines whether they can distinguish between different sound sources.
The human ear can perceive an extensive range of sound intensity, necessitating the use of the logarithmic scale to define a physical quantity—the intensity level. It is a ratio of two intensities and...
