Research question: How can different methods of listening to music have an effect on the transmission of musical sine waves?Introduction:The music is a universal language. It is a part of culture that has existed for thousands of years, dating back to the first recorded German flutist 40,000 years ago, during the Stone Age. Speech and sounds can be understood and interpreted independently, but it is how humans are able to assimilate these sounds and interpret them that is often misunderstood. Biological and psychological aspects of this process play an imperative role, including the idea that our hearing system relies solely on the cerebellum and physical movements, rather than chemical reactions that typically evoke our other senses of smell, taste and vision. However, it is the mathematical parts that make music both enjoyable and possible. One of the most popular forms of sharing music is through live performances. It is thanks to the multiple types of music transmitters and their varying frequencies that these types of live performances are even possible. Different genres of music, however, have different impacts on these music transmitters. Genres such as rock, rap, pop and classical should be played at different volume levels. Through this sinusoidal investigation, an analysis and solid understanding will be formed, distinguishing the difference between musical sounds produced by in-ear headphones, audio speakers, computer speakers and iPhone 5s speakers. In order to measure these sound waves, I will use an SPL decibel meter and a real-time analyzer to calculate the added or canceled sounds. This is similar to an oscilloscope, a device used to visualize back and forth movements...... middle of paper ...... Public Health, 2008. Web.
