How come some pros don't need room treatment?

jhbrandt thanks for explaining the difference.
Now, will this do better for sound-proofing?

These panels are 100kg/cubic metre which means they have MASS. Or should I look for sth like 1 ton / cubic metre?;)

100kg/m3 is more mass compared to 60kg/m3 or 48kg/m3, but it's not even close to enough mass to qualify as isolation. You're talking about two layers of sheet rock isolated from one another by Green Glue, floated on the studs with iso clips. Isolation is all about construction...
 
The Theory behind the algorithm for today's modern broadband noise reducers is crazy enough to make you want to jump of a bridge.
They take a sample of the mic recording only the "silent" room, and it uses that to remove the noise from the actually track. Its pretty amazing. That would be my guess. Just plug ins.

Note, that these plug ins get rid of broadband noise only (white noise) and you still need a descend sounding room, or at least to position the mic in the best sounding spot you can find.

That's for sure. If you've ever worked with noise-reduction software, it takes A LOT of tweaking to get it to work right. You're always balancing how much noise you're getting rid of with the amount of damage you're doing to the core sound in the process (unless you're ridiculously luckey enough to have the noise in a completely different part of the spectrum).

See all the stuff around them? And I've heard people saying you can't have a glass of water around you in the soundbooth or it will produce reflections.

Bear in mind that on the first video at least, im quite sure the audio YOURE hearing is from the camera, not that microphone.

Also, announcers/radio djs/voiceover workers may be using high quality dynamic microphones which are less prone to room noise/reflections.

And I hope that glass of water thing is a joke. A good room is a good room. I've played in bedrooms that are noticeably "great sounding". I love playing guitar in my living room, nice hardwood floors and a vaulted ceiling. It doesnt have to be scientifically perfect and designed by a professional to sound good. A little can go a long way in sound treatment and reduction.

When I started recording in my (then unfinished) basement, I'd go upstairs, turn off the furnace, tv, even the refrigerator. Then I'd tell anyone who was home to stfu. That took care of about 80 percent.

The other thing is your PC. Chances are ANY pc fan will be quieter than the ones that came with it. Replace those. If its still too much, spring for a custom silent set up.

THIS. +76437

In my experience, noise reduction plugins like the ones described (sampling noise) work amazingly well when you have realistic expectations. In other words do not go overboard with them because your recordings will lose a lot of their character. Bottom line, gentle noise supression goes a long way.
 
Noise reduction in SMALL AMOUNTS can work amazingly well with a GOOD gate...software or hardware, it doesn't matter.
 
Has anyone tried this, use one mic in the room that allows sound from the outside to come in. Place another mic with the same lenth mic cable (not sure if this is important though) in another room away from the artist. Then mix the two tracks together and invert the phase of the mic outside the room. It may not be perfect but it should have very little effect on the person singing but take out the noise of cars and dogs barking, also then run it through noise reduction software or it may not need it.

This may solve one problem but introduce others.......

Suppose one wall blocks frequency A but allows frequency B - with the opposite effect from the other mic (not all walls are exactly the same depending on the direction the noise is coming from - the actual frequencies - the exposed window areas etc., etc., etc.......

In that case you would block neither sound - but would actually introduce a new sound into the mix- the same goes with placing a mic outside of the building...........

Possibly but it has been my experience that noises like that are pretty low to begin with and you can always remove the offending noise from the channel on the outside of the room then invert the phase. This is the basic concept of most real time noise cancelling devices.

Tell you what - why don't you perfect the technique, write a white paper on the subject - submit it to AES and then come back to talk about it.

If it was really that simple - you could save pro studios hundreds of thousands of dollars in isolation costs.

Trust me, it (like active noise cancellation) is not as easy as you seem to think it is.........
