Feelings about the Necessity or Possibility
of Prevention of the Noise: If people feel that their needs and concerns
are being ignored, they are more likely to feel hostile towards the noise.
Judgment of the Importance and Value
of the Activity which is Producing the Noise: If the noise is produced
by an activity which people feel is vital, they are not as bothered by
it as they would be if the noise-producing activity was considered superfluous.
Activity at the Time an Individual Hears
the Noise: A person's sleep, rest and relaxation have been found
to be more easily disrupted by noise than by communication and entertainment
Attitudes about Environment: The
existence of undesirable features in a person's environment will influence
the way in which the person reacts to a particular intrusion.
General Sensitivity to Noise:
People vary in their ability to hear sound, their physiological predisposition
to noise and their emotional experience of annoyance to a given noise.
Belief about the Effect of Noise on
Health: The extent to which people believe that the noise exposure
will damage their health, affects their response to the noise.
Feeling of Fear Associated with the
Noise: The extent to which people fear physical harm from the sources
of the noise, affects their attitude towards the noise.
Type of Neighborhood: The type
of neighborhood sometimes associated with one's expectations regarding
noise there. Instances of annoyance, disturbance and complaints associated
with a particular noise exposure will be greater in areas which are typically
noted for their quiet and less active nature.
Time of Day: Noise intrusions
are typically considered more annoying in the early evening and at night
than during the day.
Season: Noise is considered more
disturbing during the summer than in winter, especially in climates where,
during the summer, windows are likely to be open and recreational activities
occur outside more frequently.
Predictability of the Noise: Research
has revealed that individuals exposed to unpredictable noise have a lower
noise tolerance than those exposed to predictable noise.
Control over the Noise Source:
Someone who has no control over the noise source will be more annoyed than
one who is able to exercise some control.
Length of Time an Individual is Exposed
to a Noise: There is little evidence supporting the argument that
annoyance resulting from noise will decrease with continued exposures,
and, under some circumstances, annoyance increase with longer exposures.
