Sample Essay on Effects of Population Density and Noise

Effects of Population Density and Noise

The number of people residing in one unit of area can be termed as population concentration. This is in relation to human beings and it is put in terms of square kilometer or squared unit of quantifying area. Additionally, it is often used for cities, countries, counties and for the world. The world’s mostly concentrated areas include cities, metropolitan states and microstates.

Similarly, population density and noise puts pressure on individuals and in different forms. The time when individual’s space and field is disrupted by persons, short or persistent noise, the resulting effect ranges from simple form of annoyance to severe illness that leads to anxiety (Straub, 2007).  Therefore, with continuous population concentration, there will be encroachment of three aspects and proper measures have to be put in place to ensure prevention of psychological effects that result from population growth.

It also helps to check anxiety, violence and frustration. This paper focuses on three concepts, personal space, privacy, and territoriality. It also analyses their impact on the people and solutions that can be employed.



Privacy is known as a ‘‘choosy management of access to an individual or a person’s group’’ Altman (1977). It also revolves around having information power concerning oneself and applying the same principle to control self-interactions with other people.  New technologies in modern world bring about different issues concerning the power of information of others. This is necessitated by description of balance as well as clear clarification between public and individual information.

The level of privacy needs as well as values greatly differs from one individual to the other and from one situation to the other and in various cultures.

Personal Space

Personal space is defined as the physical distance between individuals with a purpose of ensuring interpersonal relationships. Personal space combined with territoriality is seen as a way in which privacy is advocated for. Sommer (1969) defines personal space as a location with unseen borders surrounding the body of a person where intruders can easily invade.

This space, just like privacy is subject to change and it varies based on personal attributes, culture to culture and situation to situation. Brain development are scientific research suggests that creation and negotiation of personal space takes place in human brain. Further research studies also reveal that even though personal space has dynamic boundaries, it is of great significance and value to humanity.


Human territoriality is known as the approach of authority or control. It also means an attempt to influence, affect orImage 2 control people by asserting to enforce authority over a given geographical area. The definition also encompasses attempts by groups or individuals in any geographic scale from a room to global arena. It is also not based on survival as in the case of animals but humans maintain space via specific behaviors suggesting that action is employed in regards to ownership or it should be simply occupied.

Research studies also suggest that it is imperative to emphasize on environmental variables as a major territoriality determination aspect. As vital resources become scarce, individuals also work hard to safeguard their possessions and area residence.

Relationships with increasing population

Research studies point out that population density has major effects on population of animals and humans. It is a major issue in determining psychological effects commonly related to crowds because individuals feel bound and is restricted when they do not have major access to supplies (Straub, 2007).

Crowding occurring from high population growth has also been tied to increased violent activities, increased criminal activities, social withdrawal and inapt social interactions. To reduce crowd effects, it is imperative to ensure privacy, respect territoriality and personal space as a significant human social want. Decreased resources in relevance to space, personal space and privacy call for greater appreciation to check psychological effects.

People often have less control and more competition when personal space and confidentiality is lacking. This leads to increased tendency of negative reactions towards insignificant anger (Straub, 2007).

Perception can be considered as a revealing population density element based on its sufficient space as well as congestion related vices. When ample space is perceived by the people, they tend to build more confidence and command relating to nature and have reduced stress and anxiety.

Influence of Nature on Urban Areas’ Settlers

Zoos and parks with preserved natural settings offer a platform for support as well as a framework for people’s interaction with nature. These interactions offer an opportunity for humans to nurture and create a microclimate that is quite common in urban areas. Natural settings created in residential urban areas enhance the idea that people need to co-exist with nature.

Parks and Zoos in metropolitan areas also play crucial roles in relevance to physical activities. Research has confirmed that inhabitants of urban areas have lower health complications. The studies have also found out that individuals within green spaces areas have low mortality rates. This is because the spaces are known to reduce noise associated stress especially in urban settings.

Additionally, greener neighborhoods tend to allow for less violent and antagonistic conducts, superior intellectual performance and good interpersonal relations as well as enhanced social interaction between community members (Gidlofgunnarsson & Ohrstrom, 2007).

Impacts of Noise

Noise is known as any kind of superfluous sounds. It ranges from annoying and quiet to injurious and deafening noise. Chronic noisy places have been studied psychologically and found out to create negative impact on human populations (Straub, 2007). Damaging noise effects have also been proven scientifically to contribute to increased cortisol levels and hypertension and in the end, upsurge in levels of stress.

Contact with chronic noise levels may cause cardiovascular issues and reduced learning abilities. Loud noise is known to interfere with immediate recall ability and reduce a person’s capability to deliver simple activities. People have different noise appraisal levels and the more disturbing a person finds the noise to be, the bigger the effect on them. Even though the noise is accountable directly for effects on sleep, stress and anxiety disorders, a personal approach towards noise has unswerving effect on the health of the person (Straub, 2007).

Noise Cutback Approaches

Fabric Placement

Installation of extra fabric to cover wall decors, windows and use of fabric stuffed furnishing aids helps in absorption of noise from homes because noise travels faster on glass than on insulated walls.

Auditory Masking

This means the process in which sensitivity of sound is subdued by presence of foreign sound. Introducing simulated or second natural sound in a home can lock out foreign sound signals in homes as well as areas affected by external sources of intrusive sound.


Privacy, territoriality and personal space include private insights and preferences of humans in regards to utilization of space for normal performance. In urban settings, limited space leads to anti-social behaviors between members of the community. Noise therefore has a significant negative impact on populations thus; noise reduction approaches should be adopted to reduce chronic noise related issues.
