Sound

frequencies of sound, but they also use fatty cushions in the feet pads to detect vibrations by bone conductions. Whales abandoned their external ears to be able to swim faster, but they have also enhanced their hearing due to the exceptional way…

It relates because each new set of instruments that enters in this section presents the theme and plays something similar to the preceding line. The music has a celebratory quality when the strings are playing their fast paced but legato sound. The strings sound very happy and are almost jumping for joy. They flow and do not pierce the ear. Conversely, the music has a dark and ominous quality in the timbre of the loud horns. The loud horns pierce the flowing strings and blast the ears with…

matrix and the voids are filled with a fluid (usually air). The physical properties of the materials can be characterised by bulk, macroscopic and microscopic properties. Most of which have an impact on the acoustical performance of the material. Sound energy is lost in porous materials when it is transformed into heat. This is caused by a combination of effects. Firstly, there are losses through the viscous effects between the solid matrix and the fluid when pressure waves causes the fluid to…

Chapters Acoustics Acoustics is the properties of a space and, how sound is transmitted into it. There are four areas of acoustical concern. The first area is sound isolation, it is unwanted sounds that leak in to the auditorium that affects the performance. These problems occur through doors, windows, walls, flooring, ceiling and ventilation ducts. The second area the interior room acoustics it shows how a room size, shape surface and materials affect interior acoustics and how they could be…

felt like a wave of sound was crashing into me. The contrast between the barely audible beginning to the loud crescendo was so gradual and smooth, I almost didn 't realize the piece was getting louder until my ears couldn 't quite stand the sound anymore. A little past ten minutes, it began to decrescendo to a more comfortable volume, however it kept the same ocean wave like feel…

is the area through which air passes to create sound. It goes as far down as your larynx, up to the tip of your nose and the end of your lips. 2) Regarding inhalation, what might be some reasons that the author cautions not to “really yawn”? What does your own voice sound like when you sing or speak through the openness created by a completely full yawn? If you “really yawn” you are relaxing your muscles too much in order to produce a quality sound. You must find a balance between tense and…

first term is when you are capable of hearing but we are not paying attention to the sound. Entendre is when we are aware of the sound, ready to listen to it. Ecouter is when you are selectively listening to one or more sounds rather than any surrounding noises. Finally Comprendre is when you are listening to sound but trying to analyse it. When you hear a sound, it is known as the sound pressure waves created by a sound source vibrating.…

time were related to the American Revolution. The songs involved dynamic melodies that were used to describe the war. During and after Ludwig van Beethoven’s life (1770 - 1827), the piano gained more keys, which not only increased the size but the sound levels grew. Piano builders began building the instrument out of iron to make the noise louder and give it more depth in dynamics. Pianos began to join orchestras, which caused the orchestra to become a very popular source of entertainment.…

At some point in time, many people will experience problems with their voice. When speaking, words may sound broken, whispery, strangled or hoarse, and a person may struggle just to sound normal. In most cases, these vocal problems eventually go away, but if they don’t, then this condition may be a neurological disorder known as spasmodic dysphonia. Definition and Facts Dystonia is a neurological movement disorder that can affect the entire body or a specific body part. The primary…

perceive the information provided. Still, this gives the opportunity to the sound designer to work with the audience’s subconscious. Sonnenschein (2001) gives an example to understand the function and structure of the ear. Imagine that you are outside near constant traffic and you cover your pinnae (outer part of the ears), without however blocking the entrance to the ear canals. This will result in the high frequencies (hissing sounds) being affected, whereas the lower bass frequencies will…
