Paper on colleration between air and sound

  1. Aug 18, 2012 #1
    I am not sure if this is wright section for this question,so please excuse me if a made a mistake.
    I am thinking of witing a paper about air as a meaning of sound transfer.Does humidity,temperature etc.influence sound.It should consist experiments and theory.So could you recommend me good book or website with information about this so that i inform myself before actual work.Also what do you think about this topic is it intersting and big enough to write a high school paper about it.Thank you.

    RazorNapster, Welcome to Physics Forums!

    Your plan to write a paper about the propagation of sound in air is an excellent idea. Sound is utilized by every person who can hear and by most animals. We communicate using our voices and we enjoy listening to music. Sounds are all around us in our natural environment, including the forest, jungle, and even underwater! In our industrialized society there is workplace noise from machinery and product noise that can require hearing protection to avoid ear damage.

    In your scientific study of sound please remember these three basic elements: sound’s generation, transmission, and reception. Each element should be studied separately.

    As for reference material, here are two websites you may use to get started:

    “The speed of sound is the distance travelled during a unit of time by a sound wave propagating through an elastic medium. In dry air at 20 °C (68 °F), the speed of sound is 343.2 meters per second (1,126 ft/s). This is 1,236 kilometers per hour (768 mph), or about one kilometer in three seconds or approximately one mile in five seconds.”
    http://en.wikipedia.org/wiki/Speed_of_sound

    “Acoustics is the interdisciplinary science that deals with the study of all mechanical waves in gases, liquids, and solids including vibration, sound, ultrasound and infrasound.”
    http://en.wikipedia.org/wiki/Acoustics

    Don’t limit yourself to these websites. Using Google search you can dig deeper into any specific area you are interested in. Suggestion: use “spell-check” when you write your paper. And if you have some doubts or specific questions, come right back here to Physics Forums and let us know. Many of our members are ready and willing to assist you along your path towards more scientific knowledge.

    Cheers,

    I need your help once again.I am writing paper however i would need some non satandard experiments.I found experiments however they are too usual,I woulld need experiments that are not so standard.Thank you.

    Hi RazorNapster,

    A Google search using the terms “sound experiments” brought about 27,300,000 results in 0.36 seconds! Here are the first three that appeared and between them there are over ONE HUNDRED easy-to-do sound experiments to choose from. Quite a few of them I would consider to be "non-standard", whatever that means. Not so popular? Unusual? Abnormal? Deviant?

    I am slightly disappointed that you didn’t already do this research on your own. It is simple to do and is a free resource for information. We here at Physics Forums are standing by, just in case you have some technical questions or doubts.

    Cheers,
    Bobbywhy
