  • Radio Frequency Waves
    603 words
    Radio waves travel at 186,000 miles per second through air. In contrast, sound waves travel at only 1/5 of a mile per second. If a modulation is made of the radio wave that exactly reproduces the amplitude and frequency characteristics of the original sound wave, then sound can be transmitted rapidly over long distances. This leads to a very interesting phenomena. During a live broadcast in New York, the music will reach listeners in California a fraction of a second before it can be heard by th...
  • Third Wave Ska
    1,071 words
    SKA! Imagine this: spring break 1962, Jamaica. You are strolling down the streets of Kingston, enjoying the cool sea breeze and the delightful Caribbean climate. The streets are filled with many sounds. Cars' horns honking, children playing, and people shuffling by. There is one sound, however, that rises above all the hustle and bustle. Horns, guitars, organs, drums, emanating from smoke-filled clubs and bar rooms, fill you ears with a lush sound. This is the sound of ska. Ska is an old Jamaica...

    1,076 words
    The following is a summary of the advanced features of the AKAI MPC 2000, which include a built in sampler, sequencer and more. Here is a detailed general description of the AKAI MPC 2000. Large 248 x 60 dot LCD display with graphics. 6 functions keys under the LCD display provide various functions on each page. Built-in 1.44 megabyte floppy disk drive to store both sequences and sound data. Built-in SCSI interface for storing data to external hard disk. Here is a detailed description of the AKA...
  • Pulses Of Compressed Air Of Sound Waves
    770 words
    Resonance and Sound... Physics and Music Since sound is the medium of music, most of the physics of music is the physics of sound. It's important to remember that sound waves are compression waves. You can imitate a compression wave by stretching out a slinky (you do have a slinky, don't you?) and flicking your finger against a coil at the end. Sound waves are not like the waves on the ocean or the waves you get by waving a stretched-out rope. Take a tuning fork (you do have a tuning fork, don't...
  • Theory Of Objective Colour
    1,968 words
    Do unseen colours exist in the world and is there colour at all, the age old question The idea of sound will be investigated in the following essay. Is there sound in the world and if a tree falls in the forest and there is no body around does it actually make a noise These ideas will be followed by the theory of colour. Individuals think they see colour, so people believe there is colour in the world and do not even think twice about the issue. Still, some philosophers have presented ideas abou...
  • The Ear And Hearing Loss
    1,182 words
    The Ear and Hearing Loss The ear is the organ of hearing and balance in vertebrates. The ear converts sound waves in the air, to nerve impulses which are sent to the brain, where the brain interprets them as sounds instead of vibrations. The innermost part of the ear maintains equilibrium or balance. The vestibular apparatus contains semicircular canals which in turn balance you. Any movement by the head, and this apparatus sends a signal to the brain so that your reflex action is to move your f...
  • Intensity And Volume Of A Sound Wave
    424 words
    Sound Waves Waves are disturbances that travel through a space while changing its matter. A sound wave is what allows us to hear sounds. It is created by vibrations, which are made by the movement of matter. Sound waves must travel through a solid, a liquid, or a gas. The more tight the particles, the faster the wave will travel. This would mean that a sound wave travels fastest through solids and slowest through gases. The speed that it travels through a liquid would come somewhere in between t...
  • Differnece In Pressure Between The Sound Wave
    401 words
    In this chapter we studied sound waves. In this paper you will read about how the ear works, how acoustics work and how sound waves are used in real life in medicine and music. Some basic characteristics of sound waves. Sound waves are detectable to the human ear when the range is within 20 to 20,000 Hz. Sound waves are compressional waves also know as longitudinal waves. Sound waves require a medium to travel through. A medium is a substance or state of matter that the waves flow through. All s...
  • Vibrating Tines Of A Tuning Fork Sound
    1,363 words
    Sound is part of our everyday lives. Just like we have eyes for, we are given ears for hearing sound. We rarely take the time to think about the characteristics of sound and the ways that they are made. The basis for an understanding of sound and hearing is the physics of waves. Sound is a wave, which is created by vibrating objects and spread through a medium from one location to another. In this paper, we will look at the nature, properties and behaviors of sound waves. A wave can be described...
