Although noise, commonly defined as unwanted sound, is a widely recognized form of pollution, it is very difficult to measure because the discomfort experienced by different individuals is highly subjective and, therefore, variable. Exposure to lower levels of noise may be slightly imitating, whereas exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise produced as a byproduct of our advancing technology causes physical and psychological harm but it also detracts from the quality of life for those exposed to it.
Unlike the eyes, which can be
covered by the eyelids against strong light, the ear has no lid, and is,
therefore, always open and vulnerable; noise penetrates without protection.
Noise causes effects that the hearer
cannot control and to which the body never becomes accustomed. Loud noises instinctively signal
danger to any organism with a hearing mechanism, including human beings. In
response, heartbeat and respiration accelerate, blood vessels constrict, the
skin pales, and muscles tense. In fact, there is a general increase in
functioning brought about by the flow of adrenaline released in response to
fear, and some of these responses persist even longer than the noise,
occasionally as long as thirty minutes after the sound has ceased.
Because noise is unavoidable
in a complex, industrial society, we are constantly responding in the same ways
that we would respond to danger. Recently, researchers have concluded that
noise and our response may be much more than an annoyance. It may be a serious
threat to physical and psychological health and well-being, causing damage not
only to the ear and brain but also to the heart and stomach. We have long known
that hearing loss is America’s number one nonfatal health problem, but now we
are learning that some of us with heart disease and ulcers may be victims of
noise as well. Fetuses exposed to noise tend to be overactive,
they cry easily, and they are more sensitive to gastrointestinal problems after
birth. In addition, the psychological effect of noise is very important.
Nervousness, irritability, tension and anxiety increase, affecting the quality
of rest during sleep, and the efficiency of activities during waking hours, as well
as the way that we
interact with one another.

PROBLEMS
WITH INTRODUCTORY VERBAL MODIFIERS
Introductory verbal modifier introduce and modify the subject
and verb in the main clause of the sentence. They can be –ing forms, –ed
forms, or infinitives. They are
usually separated from the main clause by a comma.
Problem
15 Verbal Modifier – -ing and -ed Form
–ing forms and –ed forms may be used as verbals. Verbals function
as modifiers.
An introductory
verbal modifier with –ing or –ed should immediately precede the noun it
modifies. Otherwise, the relationship between the noun and the modifier is
unclear, and the sentence is illogical.
Avoid
using a noun immediately after an introductory verbal phrase which may not be
logically modified by the phrase.

Problem
16 Verbal Modifier – Infinitives
of Purpose to Introduce Instructions
An infinitive that expresses
purpose may be used as an introductory verbal modifier. Remember that a verb
word follows the infinitive. The verb word expresses a manner to accomplish the
purpose.
Avoid using a noun or to with
an -ing form instead of the infinitive of purpose. Avoid using an -ing
form or a passive construction after an introductory verbal modifier.

to the sun’s rays, using a sun screen.
