See link below indicating that black holes do hum at a frequency calculated to be B flat, 57 octaves below middle c. The conclusion may technically be accurate, but it really has no meaning on a practical level. The gases around a black hole are on average extremely thin, and even if this sound is generated on earth at stp no human, and probably no living creature of any kind would be able to come close to "hearing" it. If there is no possibility that it can ever be heard, is it correct to call it sound? After all, not all electromagnetic radiation is called 'light'.

How do you make the Canadian flag on xbox live?
You are unable to create any designs on the Xbox 360. However, I believe you may be talking about a emblem creator in Call of duty black ops. To create the Canadian flag, you first create the background, so red squares on each side and one square of white in the middle. For the leaf style logo, you will have to create it with different parts.

The high voltage does not make a humming sound. In fact, it is possible to create a high voltage line that does not make any sound. Still, you hear a sound. What you are hearing is the high voltage making something vibrate. In the United States it is vibrating at 60 cycles per second which is about A# 3 octaves below middle C. In Europe it is vibrating at 50 cycles per second which is about G# 3 octaves below middle C.
