Home Studio Soundproofing

Here what I always do when it comes to electronic. Go to http://reviews.cnet.com/ and go under reviews and look up cell phone accessories. You will get every hands free head set known to man. You will also get the reviews from both cnet and buyer’s reviews also. I have done that on a # of products and I am pleased with what I ended up buying.

I ended up with the Motorola H700 and I like it. It took me some getting use to the part that hooks around the ear.

When a jet airplane breaks the sound barrier, there’s always this kind of conical white cloud. I wonder also id the pilot can ear himself or the plane?

These vapor cones or "shock collars" (also called the Prandtl-Glauert singularity) actually don’t always happen. It is just very common at low altitudes where people happen to be filming or photographing the plane. High humidity is also a must. Also, it doesn’t have to be above the sound barrier, but only near it. In transsonic flight ,which is rougly .8 to 1 mach, shockwaves are beginning to form but aren’t fully compressed into the sharp wave that makes a boom. At these speeds and above, the wave of compressed air causes the moisture in the air to condense and form a cloud for a moment. Depending on humidity and air pressure, this cloud can be fairly constant or seem to flicker as the plane flies through pockets of moisture. Often, if conditions are dry, there will be no cone at all. Basically, when you rapidly change air pressure you can create condensation. For the same reason, in wet weather airliners can create very large clouds above their wings when flaring to land. Here’s a decent little blurb on wikipedia discussing vapor cones:

Sources at the bottom of the article are pretty good.

EDIT: The fluid mechanics links at the bottome of the aforementioned article don’t seem to be working anymore. If anyone reading this knows where to find more information on these subjects, please send me a message. Thanks.

i have herd that the sound is better with open back but closed back gets rid of any background noise you might be able to hear!!! + DO THEY HAVE TO BE MONITOR HEADPHONES!!!

You can use either type, but most recording engineers prefer closed back types. They really don’t want to hear outside sounds. They want to hear only the output of the recorder or mixer as much as possible.

"Monitor headphones" is more of a marketing thing. Just look for a good professional set - you’ll probably need to spend at least $100 US to get a entry level pair.

The Sony MDR-7506 is a great entry level pro headphone:

STS-115 Space Shuttle Atlantis blasts off from Kennedy Space Center Florida. Near the end of the clip you can see the vapor cloud as the shuttle breaks the sound barrier. This was shot by a good friend of mine, he was kind enough to get me that close to the pad, then run the camera as I watched.

EDIT: Yes, I know it’s a singularity cloud. We’ve been over this several times in the comments.

Suppose a torpedo or underwater vessel could break the ~3,350mph sound barrier. What would happen, compared to breaking the sound barrier on land/in air?

Be as specific and detailed as you like. I can handle it
Apparently it's already been done. The article doesn't talk about the effects of traveling supersonic in water, but sounds pretty cool anyhow.

The band was formed in 1980 and some time later, they recorded a four track demo that lead them to sign with MCA, who released their first album Total Control from 1983. The first album had a lot of Funk/Blues fusion with Metal, but it not sell as MCA expected, and they get dropped. In 1984 the band released the Born to Rock EP, by their own independent label, Pitbull Records. In 1986, they signed with Metal Blade and was released the album Speed of Light, with more Heavy Metal influences on its sound. After the Speed of Light release, a Italian guitarrist Alex Masi joined the band and took control of everything, leaving the remaining original members no option but to quit the band.
