By correcting for age Deaf adolescence assessing hearing, one tends to overestimate the hearing loss due to noise for some and underestimate it for others. As noise damage progresses, damage spreads to affect lower and higher frequencies.
Various governmental, industry and standards organizations set noise standards. Exposures to other ototoxins such as pesticides, some medications including chemotherapy agents, solvents, etc.
This is called a synergistic interaction. Since noise damage is cumulative over long periods of time, persons who are exposed to non-workplace noise, like recreational activities or environmental noise, may have compounding damage from all sources.
Many people are unaware of the presence of environmental sound at damaging levels, or of the level at which sound becomes harmful.
Noise damage is cumulative; all sources of damage must be considered to assess risk. Sound intensity sound energy, or propensity to cause damage to the ears increases dramatically with proximity according to an inverse square law: In the USA, Studies of primitive peoples indicate that much of what has been attributed to age-related hearing loss may be long term cumulative damage from all sources, especially noise.
People living in preindustrial societies have considerably less hearing loss than similar populations living in modern society. Among primitive people who have migrated into modern society, hearing loss is proportional to the number of years spent in modern society.
A summary report was published in Syndromic deafness occurs when there are other signs or medical problems aside from deafness in an individual. These are diseases that have deafness as one of the symptoms or as a common feature associated with it.
Many of the genetic mutations giving rise to syndromic deafness have been identified.
In nonsyndromic cases, where deafness is the only finding, it is more difficult to identify the genetic mutation although some have been discovered. A single base change in a large Costa Rican family was identified as causative in a rare form of low frequency onset progressive hearing loss with autosomal dominant inheritance exhibiting variable age of onset and complete penetrance by age The most common dominant syndromic forms of hearing loss include Stickler syndrome and Waardenburg syndrome.
The most common recessive syndromic forms of hearing loss are Pendred syndrome and Usher syndrome. The congenital defect microtiadeformed or unformed outer ear, can be associated with partial or complete conductive deafness, depending upon the severity of the deformity and whether the middle ear is also affected.
It can also be associated with abnormalities of the inner ear giving rise to an additional sensorineural component to the hearing loss mixed deafness. Dozens of additional genes for nonsyndromic deafness have been identified.Health Knowledge and Health Literacy: Preliminary Findings Scott R.

Deaf Adolescents: Finding a Place to Belong deaf adolescent’s life, particularly in terms of the family environment. The influence of Introduction: Deaf Adolescents Adolescence is generally regarded as an important time of growth and change in a child’s life.
The child is not only maturing physically, but mentally and emotionally as. In developmental psychology and developmental biology, a critical period is a maturational stage in the lifespan of an organism during which the nervous system is especially sensitive to certain environmental stimuli.
If, for some reason, the organism does not receive the appropriate stimulus during this "critical period" to learn a given skill or trait, it may be difficult, ultimately less.
