Cubicle Voice Silencer/Muffler

Hi I work in a cubicle environment with no white noise so a mouse fart can be heard across 8 cubicles in either direction. I've already been pulled in by my manager because of complaints about my voice when I'm on the phone. Can anyone come up with some device that can be placed over mouth and phone to muffle the voice? I thought of a sponge foam half sphere but I haven't tried or tested it. I'd need to find one as well! Thanks... and my co-workers will thank you as well!

Making a car purr- roar

Well this one is not that hard you just need to take off the muffler and of course a nice engine helps. I suggest if anyone wants to win this that has basic knowledge of cars and has acces to a torch-welder and saw should do this instructable. Any other suggestions for the person who decide to take this task are what this post is for. Enjoy Duck-lemon

Will a leak in my muffler cause rpms to increase slightly ?

This happens in neutral as well as when in gear.  Only talking 2-300 rpms in each case.  Will be replacing muffler tomorrow regardless.

Do turbos make a car have a whine sound to them? or is it just the rice burner?

Or is it just the rice burner's mufflers i'm hearing? I wanted to know because i wanted to put a turbocharger on a '51 Pontiac Chieftain. Obviously, i don't want it to sound like an asian car.

air mattress pump silencer

I have a big air mattress that I use frequently, but the electric pump is so loud that the apartment neighbors complain.  It takes 3-5 minutes to inflate, which is an eternity of noise when you're setting things up at night.   I just wondered if there might be a way to dampen the sound without having to use a foot pump or just leave the mattress inflated it at all times. Any ideas, anyone?

I need to re-pack a worn-out muffler for a small engine. Where/what do I buy to do the job.?

The engine is a small Tecumseh 2-stroke - no longer made, one tough little work-horse! I packed the muffler with a copper scouring pad; still too loud and poor back-pressure, which can wreck a 2-stroke, I'm told

I have 3 devices under my car connected to my exhaust, but I dont know what they are or what to do about them?

I have 3 devices under my car connected to the exhaust system. Im unsure about what they are, what I can do about them, or how I can modify these to make the car louder,lighter,and less restricted. The car is not broken and doesnt need repair, this is about modding it. My biggest concern is the last device (3rd picture), because it is big, and most likely heavy. I know the exhaust system will restrict the engine, I also know that the exhaust system has a muffler and a catalytic converter. So my question is   What is this device in the back? How can it be removed/bypassed/replaced/modified to be louder lighter and less restricting? And if I cant do anything with it, what can I do? (the devices are in order from closest to engine to farthest)

Replacement flanges for 2002 Ranger exhaust?

I'm replacing the rear half of the exhaust on my 02 ranger. (consists of the intermediate pipe the muffler and the exhaust pipe) There's a spring load gasket asssembly between the exhaust pipe (going to muffler) and the cat. converter. The flange on the cats pipe is rusted out. Anyone know if a split flange repair kit (or something akin) is available. I'd rather not do a chop job (remove the flanges on both pipes and install a flex pipe etc.)

I want to quiet a loud portable 5KW generator? Answered

I know about adding a larger muffler but I do not want to reduce the engines power by restricting the flow and that is only half the noise issue, the other half is the mechanical noise from the engine.. I have seen the sound deadening generator enclosures / shelters for them to run in but they coast 800 and up. I cannot find any plans to build one myself . Anyone know where I can find plans for one or have other suggestions?

50cc 2 Stroke Tuning? Answered

I have an old moped that I got for cheap and I am trying to fix it up. I replaced the carburetor and the new one is a little bigger even though it is off of another 50cc. It insisted on running extremely lean, but I was able to get the fuel/air mix balanced by putting some foil tape over part of the intake to get more vacuum behind it. It will only run right if the exhaust is on so that it is not lined up perfectly with the exhaust port on the cylinder. If the exhaust is taken off it will start first kick, but if it is lined up the way it should be it will not start. I took it off today and when I put it back on as close to the way it was before it would start but is now running very lean, beyond what I can tune out with the carburetor. If I give it full throttle it bogs and has no power, but it has fair power at 1/3 to 1/2 throttle. It also is getting really hot and has absolutely no power once it gets very hot. Yesterday I hat it all just right and it ran with none of these problems except that full throttle was still not where it got full power. Does any one have any ideas about what I have to do to make it run right? Maybe there is no option but careful misalignment of the muffler? --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- It turns out that the problems were that the muffler was clogged, and that it was running too lean at first, but too rich once it warmed up. Thank you for you suggestions.

Rc Airplane Guide

I have been thinking about building an R/C airplane. Here are the specifications I need. L:3ft W:4ft H:6in ( 15 with prop and landing gear Engine: Chain saw motor Prop: 12in Control surfaces: 2 ailerons, elevator I don't know anything about R/C and here are my questions: 1.) How do you assemble an R/C system? 2.) What is needed to run 4 servos(3 control, 1 throttle)? 3.) Where should I buy stuff? 4.) What else should I know? I know how to connect servos to an air frame and everything, but I need to know how to connect a full R/C system together( receiver, servos, battery, etc.). Any help? Please. P.S. My air frame will be, a wing, a wooden dowel going to tail, tail, motor and muffler. I used this design because I have no weight added other than required materials.
