Help with sound waves?

v = wave length * f.\n\nSo, length = v / f =   1,7m

You need to rephrase the question - what are you trying to do?? Manufacture? Fix? \n\nSounds like a faulty soundcard problem, but forgive me if I am wrong. To sort out sound card you will need the software for the soundcard - identify the sound card - download the software - install - done.

When it comes to speakers, check all the simple things first.  Make sure the speakers are turned on, and if they have power, make sure it's connected.  Also make sure the speaker output plug is plugged in all the way into the sound card (the 1/8 in plug on the back of the computer).  Sometimes, if a system gets moved, or a cord gets caught on something, it will pull the plug out JUST slightly, enough that you don't notice right away, but enough to where the grounding ring on the plug isn't lined up correctly.  \n\nAfter checking all that, next check the volume settings in windows.  Click on Start -> Settings -> Control Panel.  If this is Windows XP, and you're in "Classic View" the icon should read "Sounds and Audio Devices".  If you are in "Category View" it will read "Sounds, Speech, and Audio Devices".  Check to make sure the main Volume Control is turned up, as well as the "Wave" input (this is found under "Advanced") as most of the sounds on a system fall under this category, including MP3's.\n\nIf none of this works, or if you can't get into these settings, than your audio drivers are probably incorrectly installed, or have become corrupted somehow.  You were on the right track for doing a system restore, but if it didn't help you might try going to Microsoft's website for Windows Updates and try and get a new driver installed.\n\nOne more thing, if this is only an issue with your CD-ROM drive, check inside the computer for a cable that runs from the back of the CD-ROM drive down to your sound card.  It's a small cable, that provides the audio signal from a CD to your sound card.  \n\nHope this helps!!

Hi there\n\nIts really easy, I am expecting that you are using windows xp, so go to Control Panel, if in Catergory view, go to Sound Speech and Audio Devices > Sounds and Audio Devices > ( A dialog box will open ) > Select the "Sounds" tab from top. Thats all, you are there and you can change them according to your need, its all explained there.

First thing is to check if your sound card is indeed working and you get sounds in other programs.\nThen (may differ in different programs) go to Tools> Options> general> Play sound when new messages arrive

If you dont have any external speakers like the previous people suggested, try to use an equalizer to make the sound a bit louder (winamp and most media players have one). It can make the sound quality a bit worse but you would be able to listen better, This worked for me when I wanted to watch a divx movie in my summer house and I could barely listen to the dialogues.

i use sound forge for pc and soundedit16 on mac for most sounds i use.  you can also find quite a bit of sounds at Findsounds.com. usually i just connect a mic to my computer and start recording gibberish or just get a recorder and start recording stuff elsewhere.  Then i just edit it and clean it up a bit with the software.  You can probably get them and the serial off some filesharing network like limewire or something.  Or you can buy them if you have the money.  The software uses sound visiual sound waves for you to edit sounds.

1. Make sure you have a discrete sound card and/or amplified set of speakers. If not, you need to \n\npurchase an amplified set. \n\n2. Make sure your speakers are plugged in and turned on. \n\n3. Make sure the speakers are connected to the correct outputs on the audio adapter and not to \n\nthe microphone or line-in ports. \n\n4. Select Start/Programs/Accessories/Volume Control and move the Wave slider all the way up. \n\n5. Next, set the Volume Control slier a quarter of the way to the top. Now, make sure the Mute \n\nand Mute All check boxes are cleared. \n\n6. Open your Start/Settings/Control Panel/System/Hardware/Device Manager and make sure the name \n\nof your audio adapter is listed beside “Sound, video and game controllers.” If not, install your \n\naudio adapter’s driver from the installation CD. \n\n7. Open your audio adapter’s configuration utility and make sure the selected output matches the \n\nactual digital or analog connection to your speakers. \n\n8. Make sure your speakers are working properly. Plug them into an audio source, such as your CD \n\nplayer. If they don’t work, replace them.

Go into your control panel and adjust your speaker settings on your computer. Also check to see if your wires are going through the right audio ports.

Go to Control Panel then to the sound section. Mess around with it. Also look in the same section and make sure your mic isn't on mute.

Don't give up too easily on the sound wave thing.  Graphic equalization.  Sound is measured in hertz (Hz) & Kilo Hertz (KHz), Kilo being the metric measure for 100.  Start with the low tones - long wavelengths, low number of hertz.  Move up the tone scale. As the tones get higher pitched the smaller the wave lengths - increased number of hertz. Super highs, like cymbals are in the kilohertz range and so on.  It's an everyday thing that everyone can relate to .  When you hear a siren go by the tone is lower as it approches and higher, faster, as it passes you and back to lower tones as the object receeds.  Good luck.
