Jennifer Rios Negative Effects of Noise Pollution Technological progress has brought humanity numerous benefits. All types of devices and gadgets allow people to save time‚ work more efficiently and stay in touch with the rest of the world. However‚ there is also a flip side. Growing industry‚ an increasing number of vehicles and constant information overload causes a significant and underestimated problem – noise pollution. The term‚ noise pollution‚ is used to define unwanted sounds that are

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

Purpose: To investigate the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher

Speed of Sound in Air By: James Chen Lab Partner: Jin Zhang and Jake Salpeter Phys 130‚ Lab section: EE11 TA: Khaled Elshamouty Date of lab: October 29‚ 2013 Introduction Sound is a longitudinal (compressional) wave caused by a vibrating source. In this experiment‚ we use standing sound waves created by the tuning forks to determine the speed of sound in air in a tube when it reaches different resonances. In this lab we focused primarily on using standing sound waves (compressional

CCCH9008 Noise Pollution and Control in HK Two important characteristics of sound or noise Frequency of Sound Sound is the quickly varying pressure wave travelling through a medium. When sound travels through air‚ the atmospheric pressure varies periodically. The number of pressure variations per second is called the frequency of sound‚ and is measured in Hertz (Hz) - cycles per second. Loudness A loud noise usually has a larger pressure variation and a weak one has smaller pressure variation

Abstract This study was conducted to determine the combined effects of coloured lighting and ambient sound on mood. 48 psychology undergraduates‚ comprising of 38 females and ten males‚ took part in this study. This study is a 2x2 between subjects design. The coloured lightings used in this study are blue and yellow combined with the ambient sound of ‘city’ and ‘nature’ whereas mood was measured with the Positive and Negative Affect Schedule (PANAS). We discovered that coloured lighting had no significant

One philosophy that some persons question‚ including a few of our own aviation medical examiners‚ relates to our greater flexibility in granting special issuances to private pilots as opposed to air carrier and other commercial pilots. The arguments against such flexibility rotate around the thought that‚ in the event of a medical incapacitation‚ an air carrier or commercial pilot usually has another pilot on board who can take control of the aircraft and safely land. In contrast‚ the private pilot
