Experiment 7: Velocity of Sound Laboratory Report Hazel Guerrero‚ Kyle Iddoba‚ Matthew Jocson‚ Thea Lagman Department of Biological Sciences College of Science‚ University of Santo Tomas Espanya‚ Manila Philippines Abstract Verification of the relationship between frequency of sound and its wavelength and the determination of the velocity and the speed of sound in different mediums was the main focus of this experiment. The speed of sound and its velocity was determined using the resonance

Lab Sheet 1. In the lab activity‚ you will examine sound waves as they are emitted from a moving source. Predict what will happen to the sound waves when the sound source is in motion. Record your prediction (hypothesis) as an “if then” statement. (For example: If you select the GO button‚ then the train will move) If the sound source is moving‚ as it get closer to the person it will get louder and the farther away it gets it starts to fade. 2. Select the boy icon. Select the lowest pitch by selecting

The coming of sound was an innovation to cinema that forever changed the way films were produced‚ viewed and performed. Sound plays many roles in the way a film is narrated and perceived by the audience. Sound‚ as defined in the Oxford Dictionary of Film Studies‚ ‘is central to the way in which a film establishes setting‚ shapes character‚ signposts its narrative‚ directs the audience’s and instils general emotional states’ (2012: 385). Sunrise: a song of two humans by F.W. Munrau was released in

different ways of how sound particles react in many different situations. Some are able to have high chances of interaction such as reverberation and echoes‚ while other venues forced the sound to distribute or even be absorbed. Many areas the class had been taken through also had large capabilities of reflecting sound completely. The class was taken through two studio rooms; Studio A and Studio B. Also‚ the class had the opportunity to witness the mechanics of sound as it traveled

Environmental pollution is the biggest menace to the human race on this planet today. It means adding impurity to environment. The environment consists of earth‚ water‚ air‚ plants and animals. If we pollute them‚ then the existence of man and nature will be hampered. It is true that trees are being cut down rapidly. Our earth is becoming warmer. If pollution continues‚ the day is not far when our earth will be a boiling pan and become a desert. Or it will be covered with sea water causing destruction

LIVE SOUND Tim Price FdSc 2A 15th January 2010 D4: LIVE SOUND ENGINEERING.. THEORY The role of an audio engineer is no longer exclusive to the recording studio. The skill set of a modern engineer extends to video‚ radio‚ graphics and many more. One of the key growth areas for finding employment opportunities in the sector‚ is that of live sound engineering. The theory of live sound is one which combines the two things present in most musical engineering‚ technical ability and intuition. Each

Title: Measuring the speed of sound. Research question: How to determine the speed of sound by using the relationship between the frequency of the signal generator‚ f and the length of air column in the tube‚ l . Variables: Manipulated | Frequency of the signal generator‚ f | Use different frequency of signal generator which are 1000Hz‚ 1400Hz‚ 1800Hz‚ 2000Hz‚ 2500Hz‚ 3000Hz and 3600Hz. | Responding | Length of air column in the tube‚ l (±0.5cm) | Measure the

sources of noise pollution Introduction to sources of noise pollution:.. Sources of Noise Pollution Appliances used in the home such as mixer grinders‚ vacuum cleaners‚ washing machines‚ loudspeakers‚ television sets and music systems used with high volumes are the main sources of this kind of pollution. Small factories using machines cause a lot of noise pollution. Airplanes‚ .. Main causes of noise pollution: Noise is a problem chiefly of the urban area. Loud noise is considered as pollutant
