Research paper - “Sound”
We use the amazing human ear everyday to listen to different sounds for many reasons. For example we listen to conversations, we listen to music, and we even listen to common everyday sounds such as the birds and rain. However, did you know that our ears have their limits and not everyone is the same? There are levels of sound that affect us differently. The questions I want to answer are: “What level of sound is considered as a normal part of our everyday life and what level goes beyond” and “Why do some sounds lead to permanent damage and others do not?”
I want to begin by showing different ways that sound is weighed or recorded and compared. Amplitude is “the quality of being ample in size’’ or “the maximum extent of a vibration measured from the position of equilium”. Constructive Interference is “the conditions of the crests of two waves reaching a point at the same time so they reinforce one another”. Constructive interference can also be described as “the interference of two or more waves of equal frequency and phase resulting in their mutual reinforcement and producing single amplitude”. Destructive Interference, however, can be described as “the interference of two waves of equal frequency and opposite phase, resulting in their cancellation where the negative displacement of one always coincides with the positive displacement of the other.” A decibel is “a unit for measuring the relative intensity of sounds, equal to 1/10 of a bel” or “a unit used to measure the intensity of a sound or the power level of an electrical signal by comparing it with a given level on logarithmic scale.” Frequency is “the rate of occurrence” or “the rate at which something occurs or is repeated over a particular period of time or in a given sample.” Harmonic constitution “has to do with harmony as distinguished from melody and rhythm” or “music relating or denoting a harmonic or harmonics.” Pitch is “the quality of sound governed by the...
