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 irritating, whereas
exposure to higher levels may actually cause hearing loss. Particularly in congested urban areas, the noise
produced as a by-product 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, functioning brought about 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. Investigations on
human subjects have demonstrated that babies are affected by noise even before they are born. 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 affect the quality of rest during sleep, and the efficiency of
activities during working hours, as well as the way that we interact with one another.
