Daniela Alonso How does a stethoscope transmit sound? A stethoscope is an acoustic medical tool used to hear internals of humans and animals (mainly used to listen to the heart and lungs) .The stethoscope is also used to hear internal sounds of machines. They work by the principle or multiple reflections in sound waves. A stethoscope transmits sound by an acoustic pressure that the chest piece transmits. The chest piece has two sides a bell and diaphragm one the bell is to hear low frequencies

odors than at discriminating among them; women usually outperform men 5. The process by which a sound is transformed into a neural sign involves which of the following sequences of transformations? A. Sound wave : eardrum vibration: pressure wave in fluid B. Eardrum vibration: pressure wave in fluid: sound wave C. Sound wave: pressure wave in fluid: ear drum vibration D.

In her poem “The Sound Of Night”‚ Maxine Kumin recalls an experience outside with other people at night time when a whole other world comes out. She describes the many animals that thrive in the night and make noises that can be interpreted as threatening. The author appears scared of the unknown and what could be lurking in it’s dark depths. The title‚ “The Sound Of Night”‚ makes the reader begin to ponder what sounds they associate with night. I associate night with chirps and whistles and creaks

level will allow a sound signal to travel from one or more microphones to a mixing console. At the mixing console all signals will be mixed together in the right balance and levels and sent out to an amplifier. The signals are then converted into much larger signals and sent to the speakers creating sound waves for the audience to hear. (Fry‚ 2005) The aim of this report is to analyse by way of reference books‚ government occupational health and safety guidelines and various sound websites‚ the installation

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

“The Sound of the Sea” is a sonnet by Henry Wadsworth Longfellow‚ describing the sounds of the sea and relating it to human inspiration. Through only auditory images of the sea and other powerful natural forces‚ Longfellow effectively alludes to the nature of human inspiration. Through detailed and sensory imagery‚ Longfellow communicates the subtle details of the human soul and how inspiration functions. “The Sound of the Sea” consists of fourteen lines and a particular rhyme scheme (abba abba

Physikalisches Institut‚ University of Gottingen‚ Gottingen‚ Federal Republic of Germany Active Impedance Control for One-Dimensional Sound Generalizing the concept of active sound absorption‚ a system for active impedance control has been developed‚ so far for plane waves at normal incidence. The active reflector is a loudspeaker driven by the incident sound wave. Its feeding signal is derived from a "wave separator" with two microphones splitting up the standing wave field into incident and

The evolution of sound in cinema Jay Beck General histories of the relationship between sound and image in cinema tend to perpetuate an ocular-centricity (emphasizing vision over the other senses) that dates back to the very earliest experiments in “moving pictures”—a term which itself serves to confuse historians. The vast majority of cinema histories tend to relegate the subject of sound in cinema to a subordinate position by studying the transition to the sound period in the late 1920s and

The musical and film of the Sound of Music is set in Austria in the late 1930s with Europe on the brink of the Second World War. In historical context Austria has been portrayed by some historians at the first victim on Hitler’s expansionism of the Third Reich as part of its plan to conquer Europe and remedy for the injustices in the Treaty of Versailles in 1919. This treaty ‚ amongst other things‚ assigned guilt to Germany for starting the First World War and ‚ under duress compelled it to pay

Sadie Broadway Speed of Sound In Air We are studying the speed of sound in air currently in our physics class. The speed of sound is the distance traveled by a sound wave through an elastic medium during a period of time. The speed of sound is extremely interesting‚ as it’s actually the speed of transmission of a small disturbance through a medium. The speed of sound occurs constantly‚ whenever a sound is heard. It’s everywhere‚ and in air we are discovering certain factors like altitude and air
