Tubes, straws, pipes and hoses
Put things in mouth (e.q. water or sweets... don't choke!)
Balloons (scream all you can while pressing a balloon to the mouth)
Combs and paper, foil etc.
Vibrator on throat
Tubes into water
Springs (toy spring mics, Thunder Drums etc)
Shake / Rotate (poor mans leslie/tremolo)
You need to ABSORB sound partly to reduce, and partly to keep it from bouncing around (which is why it sounds like a bathroom). So THICKER things like heavy curtains or moving blankets (or quilts) or even old mattresses propped up against the wall have been effective.
If you MUST use egg cartons (which you already know are not very effective), then at least ...
It is impossible to tell without the input impedance of the speakers, but generally speaking the answer to your question is yes - you can damage either the speakers or the amp.
Say your speakers are each 8 ohms. If you connect 3 in series, you'll be presenting 24 ohms to the amp (8 + 8 + 8). This means the speakers will easily 'suck' the power off the amp, ...
Once upon a time I found and brought home some lengths of plastic tubing (intended for plumbing, I imagine). They were very long - up to 3 metres - with about a 1-inch diameter. When you sang directly into one, you found your voice pulled to one of its natural harmonic pitches (the harmonic scale familiar from valveless hunting horns etc.); being so long, ...
It depends on the power expectations and circuit design of the microphone.
Some phone lavalier mics use a LR44 battery. Maybe yours does, too. The LR44 battery, for example, has a nominal voltage of 1.5V and 105 mAh. USB has 5V and 3A (USB-C). That's a lot more power than a device using a LR44 battery would expect. If you wired it up directly, you'd probably ...
These are really broad questions. In terms of a mic. At $50 your in the Chinese unbranded territory type of microphone and most (I would imagine) couldn't give you an opinion on one that would be worthwhile. You really need to be in the $200 range before your getting into worthy entry level. I would look for a second hand bargain on eBay. Maybe old sm57 or ...
I covered my dorm room with egg cartons when I was in school. We used contact cement or a tough rubber cement (I think it was called "Goo") to stick them to the walls and ceiling. I agree with the idea of doubling the layers. you should also stagger the crates to cover the joints in the lower layer.
Besides all the other disadvantages mentioned above, I will ...
I haven't used the NT1a in a very long time, but the issue I remember having with it was being pretty cold and not having a firm core to the sound. The NTG-2, on the other hand, sounds awful. I've never actually used my own even though I got it for free from a friend (I did give it the benefit of a doubt when I first got it in the studio alright to see if it ...
Anything like what your planning to shoot is going to require foley or sound design but I can't think of anything that is ever cheaper in post. The cost to put someone up for a couple days is about a half day of work in the cheapest post houses, factor in the additional foley and sound design needed plus ADR, thats way more than a half day.
I do sound design and post and the truth is that, in this case, everything can be done afterwards.
Still, during the struggle I imagine there will be gasps, grunts, or other human noises.
If you want to capture those for sake of performance, you can focus on that.
If you don't care about those, I believe you can save the money from location recording and use ...
