Adolescents and Auditory Effects

Teaching in school can be healthily used to change the adolescents’ behavior positively and to make them more aware regarding hearing and its associated facts. In today’s world as more and more electronic gadgets are launched every now and then, adolescents often expose their ears to loud sounds. For the students to understand the basic concept of sound and sound transmission is tough because of its abstract nature. Sound is thought be a material phenomenon by the students whereas in reality it is a movement which is transmitted.

Sound is a mechanical wave that is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations. Sound is a sequence of waves of pressure that propagates through compressible media such as air or water. During propagation, waves can be reflected, refracted, or attenuated by the medium. The perception of sound in any organism is limited to a certain range of frequencies. For humans, hearing is normally limited to frequencies between about 20 Hz and 20,000 Hz, although these limits are not definite. The upper limit generally decreases with age.

auditory effects of noise
Noise exposure can cause two kinds of health effects. These effects are non-auditory effects and auditory effects. Non-auditory effects include stress, related physiological and behavioral effects, and safety concerns. Auditory effects include hearing impairment resulting from excessive noise exposure. Noise-induced permanent hearing loss is the main concern related to occupational noise exposure. The main auditory effects include acoustic trauma which is a sudden hearing damage caused by short outburst of extremely loud noise, temporary hearing loss (TTS) which gets gradually recovered when the affected person spends time in a quiet place, tinnitus and permanent hearing loss which is a result of a constant exposure to noise month after month and year after year. Out of all these it’s tinnitus which bothers most of the children.

Tinnitus is a ringing, swishing, or other type of noise that seems to originate in the ear or head. In many cases it is not a serious problem, but rather a nuisance that eventually resolves. Rarely, however, tinnitus can represent a serious health condition. It is not a single disease, but a symptom of an underlying condition. One of the most common causes of tinnitus is damage to the microscopic endings of the hearing nerve in the inner ear. It can be said that teaching helps in changing the attitude of the children in the right direction.
