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

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

A sound body is the most splendid treasure a man can cherish. A sound body means that you are so splendidly strong and well that you can bear the roughest experiences without becoming ill. The body is a living thing to be put out in the air and the sunshine. The more roughly you treat your body‚ the stronger will it be. Physical harmony is an index and expression of a harmonious mind. If one wants to build up one’s mind‚ one must build up first the body. Man has a body as well as a mind. So intimate

not everything. There is also the sound film.” Thus explained the French filmmaker René Clair in 1929. With this statement Clair was challenging us all to push the boundaries of sound design in films. From the primitive synchronization experiments of Lee de Forest and Thomas Edison to state-of-the-art Dolby Digital 10.2 surround sound‚ there are no boundaries for creating a virtual deluge of sound. Even though one is tempted to hypothesize about the future of sound design‚ it is only through an educated

Main effects of sound pollution • Deafness‚ temporary or permanent‚ is one of the most prevalent effects of noise pollution. Mechanics‚ locomotive drivers‚ telephone operators etc all have their hearing impairment. • The first and foremost effect of noise is a decrease in the efficiency in working. Research has proved the fact that human efficiency increases with noise reduction. • Too much of noise disturbs the rhythms of working‚ thereby affecting the concentration required for doing a

use of recorded sound in films was a technological achievement that would dramatically change the way audiences experience cinema. The transition from silent cinema affected many studios and filmmakers‚ who had to adapt to the new technology to prevent their careers from fading into obscurity. One filmmaker who was able to adapt to the changing industry was director Fritz Lang. The Austrian born director‚ whose career began in post-war Germany in 1919‚ made the transition to sound in 1931 with the
