What are the objectives of a physics "sound" lab?

You tell me, you the one doing the lab probably.\n\nOne of several possible objects could be to identify the speed of sound.  You might also be studying the nature of waves (wavelength, frequency, ...).

Most of these principles are addressed in detail in physics text books.  Perhaps you might try at a local college or high school  library.

there is a lot of research on sound/acoustics here is a good source of information http://www.livesoundint.com/

Sound engineers who work in recording studios make high quality sound recordings, mainly for the entertainment industry.\n\nSound engineers operate complex electronic equipment to reproduce music, dialogue, sound effects and other audio content to the highest quality. This may be for: all types of music recordings; radio, TV and theatre; corporate presentations and promotions; websites and interactive media.\n\nThe work involves:\n\n    * planning recording sessions and microphones and equipment in the studio\n    * setting and maintaining appropriate sound levels and dynamics\n    * recording each item/instrument\n    * mixing various tracks on tape and monitoring the sound using the control room speakers\n    * compiling the recordings into the final master according to the client’s brief\n    * assembling all the information associated with the recording for archive.\n\nHours and Environment\n\nHours of work vary widely and may include days, evenings, nights and weekends. Overtime may be available.\n\nMost of the work is carried out in a recording studio. The conditions vary depending upon the type of studio. Large recording organisations may have air-conditioned, comfortable, spacious, well-equipped studios.\n\nMost control rooms are intense working environments, often small and crowded and lit by artificial light.\n\nRecordings may be made away from the studio at live concerts which could be in a theatre, a concert hall, or outdoors in the open air.\n\nSkills and Interests\n\nTo be a sound engineer, you should:\n\n    * have the ability to distinguish sound quality\n    * have an ear for pitch, timing and rhythm\n    * have a basic knowledge of electricity, electronics and the physical properties of sound\n    * have practical wiring skills\n    * have an interest and knowledge of music (musical ability is useful)\n    * the ability to cope with long hours and stressful working conditions\n    * be a good communicator.\n\nEntry\n\nNo specific educational qualifications are required by the industry, although you will need to acquire some knowledge of recording technology and music. Knowledge of physics and electronics is also useful. Most entrants gain technical knowledge from taking a further or higher education course, such as City and Guilds 1820 in Sound Engineering, or BTEC/SQA National Certificates and Diplomas, HNDs and degrees are available in sound engineering, acoustics, audio or music technology.\n\nThe Association of Professional Recording Services (APRS) accredits some courses. See website for further details.\n\nTo enter a degree course you will usually need at least five GCSEs (A-C)/S grades (1-3) plus two A levels/three Highers, or equivalent qualifications. For a HNC/HND you will usually need four GCSEs (A-C)/S grades (1-3) plus one A level/two Highers or equivalent. An Access to Higher Education qualification may be accepted for entry to certain courses. Please check with colleges or universities for exact entry requirements.\n\nThe key to finding a trainee position is to gain relevant practical experience and to make contacts in the industry. You can gain experience from:\n\n    * college productions\n    * community/hospital radio\n    * rigging sound for theatre\n    * recording or mixing music\n    * working for a sound equipment manufacturer\n    * working as a runner at a recording facility\n    * work placements on higher education courses.\n\nSome studios will employ new entrants as assistants, or runners, to work wherever they are needed, carrying out basic routine jobs. Their training on the equipment is then completed on the job.\n\nTraining\n\nTraining is usually on the job or through recording studios. Audio technology can change frequently and sound engineers often need to know how to use state-of-art equipment. The soundengineer.co.uk website has a list of links for professional training on specific MIDI or digital audio techniques including multimedia technology.

Acoustics. Acoustics science's commercial applications usually revolve around designing things to have good acoustics such as concert halls, theaters, etc. Good acoustics means that the sound carries well and doesn't get muddled, even in the very last seat.

The speed of sound (at sea level) approximately is 340.29 m/s and can be used as a global estimate for the speed of sound for the purposes of this calculation.  That would mean that students measuring such a sound would need to be seperated by 340 meters to measure even a 1 second delay in sound propagation.  Additionally they would need to be able to perfectly synchronize the start of the sound event and the start of stopwatch event.  Making it even worse is the need to react with enough speed to stop the stopwatch upon reciept of the signal without significant reaction delay.\n\nThe experiment would be simply to accomplish with resources to control synchronization and detection equipment, but it would not be a low-budget, high-school type of experiment.

depends on what you want to do with the sound, but generally they use geometry to create sound friendly environments. (feedback reduction,  good resonance reverb, noise reduction, and others)

ok. here is one "HYPOTHESIS OF SOUND"!\n\nLet me know if you want another one! I got plenty.\n\nlol

ok...\n\ntry this...do a little research on Newtonian versus non-Newtonian fluids. (see link)  There are several types of fluids (this is a very important topic in Chemical Engineering, so don't be worried if you don't understand all of the mathematics on this link).\n\nSet up a web/video camera above a bowl containing one of each type of fluid in the table. Make sure you have a ruler or some other scale in view of your shot. Then take turns dropping:\n1) Large marble\n2) Small marble\n3) Pencil\n4) die (singular of dice)\n\nwhile you photograph the results.  Discuss General shape differences of the waves generated by the objects.  And discuss wavelength differences (measured using the ruler in your shot and freeze frames of the video) between the different types of fluids.  \n\nThis project will yield some cool photographs and a demonstration will act as an awesome visual aid as well.\n\nHope this is what you were looking for. If not, or if you need any additional information, feel free to contact me. Good luck.

Physics ........ Is that what you are looking for?

You'll need something which measures the amplitude and frequency of the sound waves to 'see' a difference in the noises.  You can probably calculate a trigonometric function based on one particular wave within the measurement, but it won't hold true as the sounds fluctuate at random.  Possibly, you could even program a computer to calculate a random value between set parameters to account for this fluctuation.\nI'm not a math person.  Can't help you much more than that.

I'm guessing the project needs to be an experiment and not just a demonstration.\n\nWhat area of science are you expected to work in? Are you allowed to use live subjects? \n\nPhysics:\nHow does the length of a string affect the period of a pendulum?\nHow does the density of a material affect the speed of sound?\n\nBiology:\nHow does the color of a light affect the growth of a plant?\nHow does caffeine affect a rat's ability to learn?\n\nAnother thing you might do is Google science projects or go to the library and look for a book.

i agree.  sound waves are comparable to waves in a fluid, like water.  A good way to test the reflectivity of a material would be to see how strongly water ripples would bounce off of a wall made of that material.  If you picture disturbing water near a submerged marble wall, you could imagine that the waves would bounce off quite neatly compared to how water may reflect waves from a styrofoam wall or a rough, jagged rock surface.  So, bottom line, dense smooth surfaces produce the best echo.
