Resonance RESONANCE: " The property whereby any vibratory system responds with maximum amplitude to an applied force having the a frequency equal to its own." In english‚ this means that any solid object that is struck with a sound wave of equal sound wave vibrations will amplitude the given tone. This would explain the reason why some singers are able to break wine glasses with their voice. The vibrations build up enough to shatter the glass. This is called RESONANCE. Resonance

Noise Pollution The nature of sound Sound‚ a manifestation of vibration‚ travels in wave patterns through solids‚ liquids and gases. The waves‚ caused by vibration of the molecules‚ follow sine functions‚ typified by the amplitude and wavelength (or frequency) Sound waves of equal amplitude with increasing frequency from top to bottom Reflecting on noise “Noise" derived from "nausea‚" meaning seasickness Noise is among the most pervasive pollutants today Noise is unavoidable for many

Noise Pollution Construction sites‚ highway traffic‚ emergency sirens‚ and barking animals are not just an inconvenience to the ear‚ but what researchers call noise pollution. Disturbing sounds such as these can interrupt sleep‚ a family dinner‚ or any other normal activity‚ and as a result reduces the quality of one’s life. Although it is looked over by many; noise pollution can have serious negative effects on the environment and the human body. The environment is effected greatly by loud sounds

Sound A. What is the definition of Sound? Sound is everything that a person‚ animal or computer can hear. It can be created in a countless number of ways and occurs from anything as simple as tapping on a table. All sounds are a series of vibrations that travel through a medium in all possible directions. The cause of sound is the vibration of an object; once the item vibrates the sound waves then radiate outwards until they are either stopped or they die out. A sound wave has three characteristics:
