I was just messing around with all of my extentions and i found the beep object. I thought hey cool i can choose the exact frequency so i messed around with it for a while and made a frequency tester i tested my speakers and their frequencys are
Speakers:Emachines Computer Model W0240 Standerd
Hi Frequency:18750
Low Frequency:37
So I was just wondering what others Max frequencys were. If you dont know oof hand and cant find out then use what i used:

My lowest was 37, I'm not sure what my highest was, because it paused for a second like a sound was playing but I couldn't hear anything. Btw, A human can hear between 20-20000 HZ. We've been doing stuff with frequencies in science because we're doing Light & Sound, so now I'm going to try and make a random music player .
I used to have a little thingy that let out a whine only one in seven people can hear, that fit in a PC drive bay. I never used it, but the point was to annoy people at LAN parties.

Some people can hear CRT Monitors and others can't.
I can always tell when a TV's muted nearby cos there's a high pitched noise it has. I always thought everyone could hear it till I found a few comments about it on the net. It's very common though.
I think computer CRT monitors are beyond in frequency to what people can hear. The lowest frequency supported by VGA monitors is 31khz, and human hearing is at most 20khz. A regular tv runs at 16khz though, so it's audible by some people. This applies to regular 50hz/60hz interlaced scanning crts, not to 100hz or progressive displays.
- Ok, you must admit that was the most creative cussing this site have ever seen -
Yeah, probably. All I know is it drives me nuts when Dad has the TV on mute, lol.

Whenever the TV is only Turned ON, I can hear it. It's pretty annoying.
We also had this mosquito remover (or whatever it's called) that sends out a high noise. But because I could hear it all day, we had to throw it away.
Phrizzy is sort of right, It is not the mains transformer as modern televisions do not have one, they have cheap switch mode power supplies instead, nor the CRT you can hear, its the Line Output Transformer 'LPT' (known as a "loptee").
This boosts the voltage for the anode on the CRT to at least 20kV, at the line frequency - which for British televisions is 15,625 Hertz, for 625 lines - which gives the annoying whistle.
Or you may be able to hear the switch mode power supply (They usually run at 2-5Khz), they work by switching the mains on for certain fractions of a second, thus controlling the average power as the mains may be only on for a 1000th of a second for example. Horrible things, used in computers as a 550W transformer would be probably about 5 times the size of my PSU, and weigh a boat load.
They are horrible as when they go wrong, they can put "her majesty's" mains onto your motherboard as there is no step down transformer, and they don't take too kindly to 230V RMS at 50Hz...
So now you know, leave your electrical appliances alone!
You need an internal speaker. Not all computers have them, and if you built the computer yourself, you're less likely to, although if you built it yourself, you'd probably know you didn't have one.
thinking is like pong, it's easy, but you miss sometimes.
