I like to DJ in my bedroom almost daily. The only problem is that I can
barely turn it up without annoying my roommates or the people who live next
door. Is there anything I can do to prevent them from hearing me? I mean,
I was thinking about purchasing some mattresses and placing them on each of
my walls to act as some sort of insulation. Will this prevent/lessen the
sound from reaching them? Does anybody else have any other ideas??? Thanks

Yah man, I hear ya' on that one; but why haven't you considered getting a
pair of high quality headphones? You mean to tell me, that the notion of
headphones has never crossed your mind? =) Everyone has their own opinion
on headphones, but I have used Sennheiser's for years and they sound
awesome.

Dont waste your money on matresses.. go get some foam rubber and line your
walls with it.. my friends had a band and used to practice in thier garage
and they had it covered in foam.. worked nicely.

Do all of your mixing inside the headphones(if your mixer has the function to do so,PGM mix etc) & no one will get pissed off.

My Co-Worker, when he used to DJ in his house he bought airplane
insulation and lined his walls with that. If it can keep a jet engine
almost quiet, I am sure it could help you out. The thing is I don't
know where he got it. I imagine an airplane parts distributor.

I prefer to practice like live; in other words, one cup, listening to my
monitors loud. Otherwise you'll get confused when you're doing a live set
and all that noise is blasting your head.

The primary thing is the bass - and the number one way to remove bass from
yoru neighbors space is to "mechanically isolate" your speakers from the
floor. Put your speakers on stands. I used milk crates, upside down, then on
top is eggcrate foam, and on top of that is a cardboard eggcrate [like you
get at the big grocery warehouses with 3 dozen eggs] and on top of that is a
square piece of drywall. The speaker stands on top of all that. It not only
absorbs the energy of the speaker cabinet [which makes a lot of the
vibration in the floor] but the bass radiating from the bottom of the
speaker is isolated as well. There is NOTHING you can do about all the bass,
because it is omnidirectional. [meaning it travels every direction]

If you have a common wall with some particularly un-friendly neighbors, you
can get a BUNCH of eggcrate and staple it to the wall. You can easily cover
the whole wall in a small space. It doesn't look pretty, but it's what small
sound studios use if they don't want to spend a lot of money on acoustic
tiling. It won't be a catch-all, but it will help muffle some of the higher
frequencies.

Also, I would recommend sitting closer to your monitors than you would live,
so you don't have to listen to them as loud.

--I have a problem though. I built those speaker stands a few weeks ago, but
I just bought a 2400watt PA system with 4 cerwin vega loudspeakers, and i'm
itching to try it out! Time for a party...

The guy right before me knows what he's talking about.
Put the speakers on stands, and move the speakers closer to your ears and aimed
at them. I would even recomend tall stands to really get them aimed right.
If you have to start putting things on the wall, I disagree with the egg-crate
fad. This will cut down on reverb, but will do little for SPL (loudness). If
you want to cut back on loudness (especially from the bass), the cheapest and
most effective way is to hang some thick carpet, or cheap rectangle oriental
rugs (look cool). But the key is to leave about a 1 foot gap between the wall
and the rug. Make sure the rug goes completely from the ceiling to the floor
and no gaps. The bass will get trapped in the gap. Three seperated layers is
even better.
Bass is hard to deal with, so good luck.

Excellent! I'm heading out to Jet Supplies Plus first thing tomorrow and
gettin' some of that! Wait, they are open 24 hours and stock everything from
jet engine insulation to airplane toilet seats. Visit their new freeze dried
food section, too! The special this week is salsbury steak and carrots, with a
bagel and bag of unsalted peanuts. Over in their electronics aisle, pick up
the new FAA approved radio scrambler. Great for playing pranks on the pilots
as they are waiting to take off.

Or, the ultimate purchase: your very own black box. The pros swear by
the fuuristic-looking new silver-finish Sonys -- especially the
SilverBlackBox-DJ700 model -- but if you're tight for cash, try
covering a shoe box with shoe polish (available from your local shoe
parts supplier).

(Note for newbies: You need a black box because if you strap one to
your ass with duct tape for the rest of your life you'll be
indestructible.)

Heh, I went to one a few weeks ago. You can't buy crazy shit like
black boxes. You can buy insulation and you can buy a bolt for
landing gear that costs a few hundred dollars....

other restaurants you get the cardboard trays, i think they're made of
paper pulp and poured in moulds, they'll work just as well, and for
some people are a bit easier to get. Foam on the wall is BAD idea, it
will work, but it is highly flammable, and if it does burn, the fumes
will kill you very quickly, there's quite a few horror stories..

While you're there, pick me up some of those well-built paper bags.
I'm going to need some next week, when the Backstreet Boys sing during
the Superbowl.

I already built mine. All that comes out of it are the sounds of 3
Italian guys and a woman wailing "Whoaaaaa-Ho !!!!!!"

You can do something. Insulation is usually the first thing people
look at, but have you considered getting a crossover and setting all
of your speakers on the high pass for frequencies over.....let's
say...30 Hz? It is very hard for normal building materials to suppress
low frequency noise, that is why it seems to travel so far. When you
think about it, all frequencies travel the same distance, or at least
have the potential to do so. The only reason high frequencies don't
make it as far is because normal materials around us are able to
absorb and kill those frequencies. If you cut out the frequencies
below 30 Hz, your neighbors won't feel as rattled by your music, and
it should still sound very satisfying to you. Most clubs will not run
frequencies below 30 Hz because those frequencies attract cops, and it
is around 50 Hz that gives you the nice kick in the chest thump.

Very good suggestion. Check out the JBL Sound Reinforcement manual to
figure this one out. The gap is the KEY part. A heavy drape will even
go a long way.

The best suggestions I've seen so far include moving the speakers away
from the walls and onto stands.

Moving yourself closer to the speakers or using headphones.

Using insulation that has a gap between itself and the wall, and even
going so far as using layers of gaps. The gaps will help get rid of
multiple frequencies. The distance of the gap is key in reducing a
specific frequency most effectively.

I still suggest cutting the ELF's. You don't need them, and they
primarily serve to annoy your neighbors and get the rocks off on car
audio nuts. Notice they get tickets for being too loud!

The reason high freq waves don't go through walls is because they're very short.
Bass freq are very long (literally a number of metres) and therefor travel through
walls and floors.
Science lesson over.

While it's true that the wavelength is short (length per cycle), this does
NOT mean the wave itself is short.

They do so because the energy needed to vibrate an object (ANY object) at a
certain amplitude goes to the square of the frequency of the excitation.

DO note that there is NO mention of any length of the wave here!

> Science lesson over.

Probably so.
