1. INTRODUCTION
Many places are becoming urbanized; so to save space many people live together in one building like apartments or a duplex house. There can be lots of noises generated by activities such as walking from adjacent buildings. The noise impact on people’s quality of life goes beyond annoyance. It may affect psychological aspect of health as well.
There are several ways to eliminate this problem; one is to reduce sound by increasing the distance between the source and the receiver and the second is using noise barriers to reflect or absorb the sound. To effectively reduce internal noise transferred from the adjacent buildings and maintain the comfort of the resident, it is important to have adequate sound floor insulation. Sound insulation in a building reduces the sound pressure with respect to sound sources and receivers.
In this report, I will discuss the installation of a sound floor insulation that reduces noise from outside. Additionally, I examine effects and causes of the noise.
Most of information I used in this report was collected from the recent technical databases provided by Kansas State University Libraries. I have also gathered relevant information in academic journals.
This paper is organized into three main sections. First, Section 2 provides brief problem of the noise. Second, Section 3 discusses the way to reduce the noise from neighboring units by installing adequate sound insulation. Third, Section 4 summarizes my research findings in a
b. Explain either what effect the density of a material, or the frequency of the sound would have upon the attenuation of sound travelling through that material. (Chose one or the other)
Enhance the social experience. There is usually no parking or services for providing food and drinks, and going to the movies is looked at as a social engagement that are attended in groups. Box seating with sound barriers would enhance the experience for these groups.
Noise can be very distracting especially if someone wants to study, sleep, read, do homework, and do a project or anything else. I personally have experienced noise as a distraction and I would never intentionally try to distract someone from doing what they want buy making it hard for them to focus because of my noise.
For many people, noises in the environment may not be an annoyance, but for others who are noise sensitive it can have several numbers of negative effects. There are some cause-effects such as difficulties concentrating in the classroom, at work, and/or personal life. It can also go as far as causing internal organs damage. For example, the learning process of a child facing this disorder could be more difficult, according to Tremmel “a child’s brain has to work overtime in a noisy classroom to do its typical, but, very important job of distinguishing sounds whose subtle differences are the key to success with language and reading”. Even though, from early age people learn how to localize and identify different sounds that will help them throughout their life, there are some people that suffer from noise sensitivity and it can make their life a bit hard, because certain functions of their brain can be affected. Noise Sensitivity (NS) is a physiological and psychological internal state in which the noise level of certain things can be uncomfortable for an individual in doing their daily tasks. In the research paper by Kliuchko, et al. (2016), he states that “the human ear and brain come together to adapt to the acoustic environment and that the auditory cortex can adapt in a way that can be tolerated for each individual”. In another study done by Dr. Schnupp’s from the research team at the University of Oxford has been “found that the auditory neurons in the brain are
Noise is one of the most widespread causes of hearing loss, and the most likely causes of occupational illnesses in the United States (Leigh 728). Acute or prolonged exposure to high-level, impulsive noise is an ongoing problem for the military and defense forces all over the world (Sliwinska-Kowalska and Adrian Davis 274). One shot from a big caliber firearm, perceived at a close range, may permanently or temporarily damage an individual hearing in an instant. Additionally, repeated exposures to noisy machinery may, over an extensive period of time, impose serious risks to human hearing. According to the report released by National Institute on Deafness and Other Communication Disorders (NIDCD); ten million Americans have already suffered permanent hearing damage from noise and thirty to fifty million individuals are exposed to hazardous noise levels every day (Leigh 728). Many hearing illness in the police service originate from the noise caused by gunshots. As a result of increased cased of hearing problem, mainly in the police service, many scholars have engaged in research in order to get appropriate mean to control these problem. Considering the increasing investigation from military groups for vital information on how to protect from impulse noise, it is vital to explore health effects associated with impulse noise from gunshots. This study explores the effects on hearing caused by
The author explains “I’m in a large control room filled with computer banks and work stations, which make for convenient blocks to hide behind as I dodge the stalking alien moving through the room” (Hornshaw 2). Again the author displays good use of storytelling, but much is left out in the recounting of the events. He doesn’t explain the way the light shimmers off of every corner of the room, the way the alien’s tail seamlessly cascades and slithers over every object that it comes into contact with, the way characters’ sweat accurately drizzles over the complexity of their near natural looking faces, or the way the fog and smoke gently drift through the air being wisped in tiny curtails as active entities glide through them. All of these systems are being algorithmically controlled and provide engagement with the player, engagement that the article does not portray very well. In another division of the writing, Hornshaw narrates his experience with the game’s audio, telling about how he can perceive the alien rumbling through the ventilation systems and hallways of the space station (1). But again, his overall explanation of the sound quality is lacking. There is a constant groaning and grumbling of machinery in the background, which adds to the awe-inspiring moments of
Share your opinion on whether the maximum volume of these devices should be regulated. In my opinion, regulating excessive loud of noise can be positive outcome of hearing loss. According to “The National Institute for Occupational Safety and Health (NIOSH) has recommended that all worker exposures to noise should be controlled below a level equivalent to 85 dBA for eight hours to minimize occupational noise induced hearing loss.”
Have you ever been to a movie theatre, sitting at work, or hanging out at home and heard people eating, talking, or making repetitive sounds? For some, these are just regular everyday noises. But, for others these noises are so loud and disturbing that they literally become triggers for anger and cause people to distance themselves from social gatherings, family, and personal life (Kumar et al., 2014).
There are several specific questions this paper seeks to answer. One question is about animal models. They are often used as stand-ins for studying humans. These animal models provide much of the foundation of our understanding about the effects of noise in the elderly. Several animal studies will be examined, and the similarities and difference will between them will be compared, and the limitation of the aplicibility of animal model to human research will be discussed.
“I was amazed at what a difference [the upgrades] made – my home isn’t just pleasant and comfortable, it’s quieter too. I would definitely encourage other homeowners to get these upgrades.”
Now in this paragraph I will be telling myself why I shouldn't make a lot of noises underneath me, and I will answer my question that I put in paragraph one. Now, like I was saying if I make enormously amount of noises the creatures under me can really have bad time hearing their families
While researching I came across a website called, livescience.com which talked about the certain elements found in houses which gave them a supernatural feeling. The first explanation for supernatural feelings was credited to the sounds present in the room. This essentially means that different sounds trigger various emotions from all kinds of people. A study was created which used two groups and each group was “exposed to infrasound or to ambient noise.” Both groups were led into a haunted building and each group was exposed to
Environmental modifications to improve access to sound signals (e.g., improvement of classroom acoustics or use of personal FM equipment).
Parents and teachers can modify the child’s environment to learn by guarding against interior noise sources by checking the volume level on the child’s music devices. If the iPod or Walkman is too loud it can distract other students in the room because the music might bleed through the headphones. “If he listens to his favorite music too loudly, make proper volume adjustments. Also monitor the volume level on computers, televisions, and other electronic devices, keeping them as low as possible.” (Evans,
As a result of per the Building laws, the insulation is against airborne sounds like voices, not against the impact of sound against the walls like hammering a nail, noise pipes or vigour bed sheets. Once sound meets the building, like a floor, a ceiling or a wall the sound reflects back to the area, a part of it is absorbed by the fabric and the left over is transmitted to the succeeding area. The sound absorbed, mirrored and transmitted depends on each of the thickness/thinness of the wall as well as the material on the wall. (Figure 1)
