Acoustics
Acoustics deals with the study of sound, which is of mechanical waves in liquids, gases and solids. The term ‘acoustic’ comes from ancient Greek and it refers to the ability of being heard. Acoustics studies the sound from production and control, through transmission and to reception and effects. The initial studies focused on mechanical vibrations and their radiations through mechanical waves. These studies are still continuing in the present. Waves and sound involve physical processes, which, in their turn, have various aspects that researchers are trying to focus on at the moment.
What is now a science – acoustics- has been discover through trial and, more often than not, error and this process took hundreds of years. Studying sound waves, scientists have found physical principles which they can now apply to the study of all types of waves. The sound waves physical processes are under analysis as to how they could be applied in modern life.
When referring to acoustic noise, most people mean a sound of greater volume than the usual. In fact, anything that disturbs a certain environment may be considered noisy, such as the loud music played by your neighbors or the sound of an aircraft. Even conversation of people may constitute noise to other people who do not take part in them. The worst effect of such noises takes place when they prevent certain people from receiving the messages that are transmitted to them. One clear example is the classroom, where noise control should be a priority. The students’ ability to hear verbal information is often reduced because most classrooms have poor acoustics which allow background noise inside. Such background noises can either come from outside the school, such as traffic or the playground, or from inside the school, from the hallway, lunchroom or gym. These problems could affect young school children in what their reading or spelling skills are concerned. School facilities situated in areas affected by powerful noises such as those of aircrafts and traffic should be primarily focused on. In such situations effective instruction in the classroom can only be obtained through acoustic noise control. Solutions to reducing background noise are numerous, but the teacher can’t always amplify his/her voice, carpeting or drapes are not as efficient as expected, and it’s not always possible to reduce background noise even if intended. Under the circumstances, sound absorption seems to be the best solution.
The teacher -student communication is the basis for productivity in learning. But in situations when this communication is not functioning at its best because of reverberation level and background noise within the classroom, the productivity is affected. If noise is a problem within the classroom, the best solution is the use of noise control and sound absorption products. All these products are fire rated. Many noise control products are cost effective because they are made of recycled materials and thermally bonded. More over, noise control and sound absorption products are strong and durable, water resistant, easy to assemble, non-corrosive, and they come in a wide choice of colors. Such noise control products may even be graffiti resistant.
The bottom line is that if your school has noise problems, you should resort to noise control products which will provide the best solution to your problems, as well as significantly improve the quality of the education process.
