How can I simulate the audience already being there? Is there anyway I can anticipate it very well? Simulate, you can't. Anticipate, you can. Rule number one: use your ears. Always. During the soundcheck as well as during the concert. This is a general rule that is not specifically related to your question, but you can't solve the problem as soon ...

Let me just give a general answer here, because many people might end up in this situation today or tomorrow. You could do several things to get rid of this boomy sound. In my opinion, you are using too many microphones to do this recording with. First, two items apart from microphone placement. Getting rid of the boominess If you record in this same ...

First of all, standing waves (i.e. flutter echoes) are your worst enemy. To figure out if you suffer from these guys: make the room silent and clap your hands. Can you hear a nasty tone, or does it just sound like regular accoustics? Try at different places. Flutter echoes normally come when two parallel stone walls are against each other. If you find a spot ...

Remember that one of the biggest variables you have, is the performers on stage. They are not likely to sing or play at the same volume levels in practice as they are when performing. I personally don’t put much value in a sound check beyond verifying that all the equipment is working properly and the audio levels are at least somewhere in the ball park of ...

If you do a bit of reading, you'll find that the optimal position for you to be in can be calculated based on the shape of your room, and that the center of the room is a sub-optimal listening position. The reason that you hear less bass in one position than in another is because reflections from your walls and other elements in the room work together to ...

A couple of the answers above have parts of the information. The brain uses interaural, time, amplitude, frequency and phase differences to locate sounds. In the case of the sounds coming from behind you versus those in front of you, time, phase, and amplitude will be equal at both ears for the most part. However, there is a frequency difference due to ...

Directional mics (eg cardioids) work by allowing sound to reach the rear of the diaphragm as well as the front. Because the sound wave travels further to reach the rear of the diaphragm it is delayed and so is out of phase with the wave at the front of the diaphragm. This phase difference causes a pressure difference because the two waves, one front and one ...

I believe that the pinna of the ear causes a frequency filtering effect as well, when the originating sound is behind the head. See this Wikipedia article. NCH Article. This fact is being used in hearing aid development and construction to improve localization results for wearers. One hearing device manufacturer that I'm aware of, Unitron, has even branded ...

how do we distinguish the sound as coming from front and behind? Good question. We don't. I'm often searching birds by sound in the field and I'm often confused with this. We often have quarrels with my girlfriend whether the bird was in front of us or behind :-) You have to turn your head to the side, little bit off the axis. That's also why some owls have ...

You should check out this site. He is very helpful but you must read his requirements for activity on his forum very carefully. http://www.johnlsayers.com/phpBB2/index.php. Also this http://www.ethanwiner.com/acoustics.html Bass trapping is the main place to start. I wont explain bass trapping here as you could spend months studying it but I can tell you ...

Ideally you want to use a sound absorbing foam on the walls and ceiling - like this. You can buy panels already made, which will look better, but even just attaching foam like this to the wall will help deaden the sound. Use a carpet on the floor, and have thick curtains or rugs to hang over the windows. All these things will help absorb sound.

For a solo acoustic instrument recording, I would find a nice-sounding room and try to capture the whole performance with a stereo mic setup. By "nice-sounding", I mean No noticeable external noise sources (traffic, air conditioning/heat, etc) "live" (reverberant) but not too live. You can damp liveness with carpets, furniture, etc. Not so small as to ...

Unfortunately this is just part of the job (in my experience.) There's no real way I've found to compensate for a mass of bodies in an otherwise empty hall, you just have to do it "on the fly." If there is feedback, check your mic positions relative to the PA, also cut out some of the higher frequencies in your rack. Unless someone else knows a way to ...

Also sometimes feedback occurs when the levels are put up. During your soundcheck you should turn your volume up to the point that you get feedback, identify what source is causing it and use a Graphic Equaliser to turn down the frequency that is feeding back. You may find that you will need a Graphic EQ on more than one channel. vocalists hear ...

Go figure... ask a certain number of audiophiles a question and you'll get an equal number of answers. Here's my take: The dulcimer, like the piano, is a percussion instrument which has two basic tonal elements going on. You have the initial strike of the hammer and then the resonant response of the string/chamber/soundboard. When afforded the luxury, I ...

A good reference on this subject can be found in Master Handbook of Acoustics by F. Alton Everest. The various shapes of acoustic foam are more for aesthetic reasons than acoustic. The contours may have marginal benefit in diffusing the sound field by means of acoustic refraction. The more complex the sound field of your room, the more "open" it will ...

Everett's Acoustics is indeed strong; however, a few caveats First, Everett's book is unmanageable without at least a basic grasp of electronics. As a first-year electronics major, I would say I understand about 50% of it. Second, Everett's book is haphazard. One or two chapters are devoted exclusively to software simulation, which is near-useless for ...

There are a lot of questions in there, so you may be better off posting them as separate questions... but here goes anyway: Acoustic foam is probably the easiest thing to remove echoes from a normal room - it's also simple to remove if your needs change For cost saving purposes you may not want to cover the whole wall, so interspersing shapes will at ...
