Architectural acoustics

Indeed, it is indisputable that there is persistent environmental degradation, and this sparks worry that the globe may never meet its global goals. The globe has been yearning for sustainability, which, as policy makers put, may never be achieved but for appropriate social, political and environmental management. The world has looked to technological developments to intervene in the realization of sustainable development, and engineering development has seemed to respond well. As far as the engineering is concerned, sound production has far-reaching implications on the environment. Sounds are pressure vibrations that travel in mediums such as gases, liquids and solids. The most common type of sound perceived by human ear is that which travels through air. Sound could be constructive or unconstructive. However noise is generally regarded as unwanted and destructive sound. In work environments or even in home setting, it is preferred that noise should be reduced effectively since it can affect the ability to work, concentration and rest. These noises range from loud music, traffic and building services (air ducts, pumps etc.) to neighbor activity. Noise production is still rated as one of the serious rampant forms of environmental pollution. Noise pollution continues to affect human health, as well as behaviors. Noise pollution has the can trigger annoyance, as well as aggression. Noise is also associated with high stress levels, disturbance of sleep, hypertension and tinnitus. It is worth noting that stress and hypertension are among the current serious threats to human health. Loud noise can also trigger cardiovascular diseases, resulting from increased blood pressure caused by noise. Noise does not only affect human beings, but also other organisms. For example, noise can affect wildlife by increasing the death risks by triggering an incapability of the predators to detect the prey. Introduction of noise in the new ecosystem can also reduce the portion of a usable habitat by either scaring away organisms or threatening them to extinction through the harmful consequences. Thus, process of curbing noise pollution is critical In this regard, curbing the amount of noise has been one critical area for engineers in their quest for sustainable development and production processes. Environmental engineers have defined the ability to control sound in a closed environment as Architectural Acoustics. Designers and engineers have studied sound and how it acts in an enclosed environment. They have further come up with different ways in controlling noise levels. Attenuation is a method that is used to achieve control of noise levels, which is immensely taken into account during the design process of dwellings (McMullan, 2012).This laboratory experiment will further expand on the understanding of controlling sound and noise, and the use of building materials throughout the process, in addition to what materials are most efficient in providing insulation, absorption and isolation (Attenuation methods).In this experiment, a (TES 1351) sound level meter, as well as a sound source (electronic buzzer), was used. 2.0 EQUIPMENT USED: In this experiment, several equipments were used, including: Sound meter (TES 1351). Sound source (Electronic Buzzer). Acoustics box kit that consists of a wooden box, foam lining and a barrier. 3.0 METHODOLOGY: To ...Show more

The Court has to explain if nondelivery of the certificate means nondelivery of title of care. Under the Wisconsin counterpart of N.Y.U.C.C. § 2-401 (2) “Unless otherwise explicitly agreed title passes to the buyer at the time and place at which the seller completes his performance with reference to the physical delivery of the goods, despite any reservation of a security interest and even though a document of title is to be delivered at a different time or place…”1 Moreover, according to Gilmore, G.2, the range of documents of title does not include automobile certificates of title, as the Uniform Commercial Code has not granted them this legal statute.
