Description
ABSTRACT
Noise generated from social club is mostly an acoustic noise. Levels of noise generated from social club were measured. Noise levels as high as 116dB was obtained. These levels of noise can result many health challenge in human being. It is capable of causing temporary and permanent deaf. Noise spectra generated from social club are mixture of low and high frequencies. Low and high frequencies noise can have negative effects on memory. The levels of noise generated from social club were very high and are above the international standard value. Critical investigations showed that these noise are as a result of no proper regulation by the government, thereby gave rooms for noisy musical systems that produce noise.

1.0 INTRODUCTION
The ability of man to make and detect sound offers him the opportunity to communicate and receive valuable information from the environment, namely; sound alarm, music, television and others. Noise generated from social club is differentiated from those of the community or local market places. The major sources of social club noise are musical sound and noise from club attendees. On noise studies, more emphasis is placed on the negative effects, that is, the pollution aspects. Noise can keep our senses on edge and thus can prevent us from relaxing. Our mental powers control this insults to our bodies resulting into deafness over a long period of time. Also as an insidious pollutant, damage is usually long range and permanent, yet it is certainly the pollutant of least public concern and perhaps the least understood [2].
In most cases, especially in these studied sites the social clubs were almost located close to residential houses, when there is no enough distance between the social club and the residential buildings. This cause direct transmissions and accumulations of noise doses to the residents.
1.1 BACKGROUND OF THE STUDY
Noise pollution is the emission of continuous undesirable noises disrespecting legal levels which, within a specific period of time, pose a threat to human health and collective well-being. Noise may be described as aperiodic acoustic signals originated from the overlap of several vibration movements with different, unrelated frequencies.
Noise has been increasing over the years, specifically in large metropolitan areas. This increase is also perceived inside public places such as market. Different noises originated from distinct sources, such as the operation of different devices and conversation among grinder cause noise pollution in the Ado-ekiti environment and this may affect the individual’s physical and emotional health2.According to the World Health Organization (WHO), noise may influence individuals’ professional performance and quality of life, as it interferes with sleep, communication, and causes physiological and psychological reactions that are, most times, considered health problems3.
The body perceives the exposure to noise as a stressful situation, responding to it with an increase in seric levels of adrenaline and cortisol, which may interfere with the recovery of a hospitalized patient. On the other hand, an environment with adequate sound levels provides the patient with lower levels of psychological stress and physiological damage, leading to a speedier recovery4.
A study has identified that 34.0% of ado-ekiti sources of noise are completely avoidable and 28.0% are partially avoidable. The authors also state that physical solutions may reduce 48.0% of the sources of noise, and team training may reduce 14.0% of these sources5.
1.2 PROBLEM STATEMENT
Evolution has programmed human beings to be aware of sounds as possible sources of danger (Hughes et al, 2013). Noise, defined as unwanted sound, is a pollutant whose effects on health have been neglected, despite the ability to precisely measure or calculate exposure from peak levels or energy averaged over time. Although people tend to habituate to noise exposure, degree of habituation differs for individuals and is rarely complete (Basner et al, 2011). If exposure to noise is chronic and exceeds certain levels, then negative health outcomes can be seen. Health effects were first recognised in social club settings, such as noise from the sound system, where high levels of noise were associated with noise-induced hearing loss (Stansfeld et al, 2010). Research focus has broadened to social noise (eg, heard in bars or through personal music players). These noise exposures have been linked to a range of non-auditory health effects including annoyance, sleep disturbance, cardiovascular disease, and impairment of cognitive performance in children (van et al, 2012). The health effects of noise from entertainment venues and from neighbours are elusive, but nevertheless, cause many complaints to local authorities. This study was carried out to analyse the effect of noise from social club in human body.
1.3 AIM AND OBJECTIVES OF THE STUDY
The main aim of this work is to analyze the effect of noise coming out from social club on human body.
Specifically, the study was set to achieve the following purposes:
- To know the effect of noise on human health
- To analyze the noise level of the social club
- To calculate noise power
1.4 PURPOSE OF THE STUDY
To assess the noise level of social club and to analyze its effects on people from reporting complaints.
1.5 SCOPE OF THE STUDY
The scope of this work covers the analysis of the noise level of the social club. Most of the social clubs are located very close to the residential buildings which is the major reason why the noise coming out of the environment can be hazardous. This study examines the noise levels in a social club. Noise measurements were conducted at line locations of the social club.
1.6 SIGNIFICANCE OF THE STUDY
Measuring noise levels and people’s noise exposures is the most important part of a environmental hearing conservation and noise control program. It helps identify work locations where there are noise problems, residents who may be affected, and where additional noise measurements need to be made.

5.1 CONCLUSIONS
The presence of low frequency noise can have adverse effect on concentration and memory. Fatigue is one of the most cited effects of low frequency noise. Low frequency noise is capable to increase cortisol values, which is an indicator of stress. Other physical effect attributed to low frequency noise include, peripheral vasoconstriction, elevated blood pressure and greater risk of cardiovascular disease. The best way of reducing the noise levels of the existing noise sources is to reduce the noise level at the source – path – receiver. At the source, the noise level can be reduced by turning down the volume of the musical devices mostly at night[15].
