The walls of expensive chambers are fitted with foam wedges. The sound goes in and cannot come back out. Egg cartons, Blankets with form rubber behind them all soak up sound. A (not recommended) thin sheet of lead will work also. Sound hits it and does not bounce off it very well.

What is involved in an EMI test?
An Electromagnetic Interference (EMI) tests are often done in an anechoic chamber, a room designed to completely absorb reflections of sounds and electromagnetic waves. An EMI test involves testing RF filters and special designs to check for unwanted audible buzz in audio appliances like a microphone amplifier or a speaker amplifier.
What device is used to detect nuclear radiation?
There are many different devices used to detect nuclear radiation, though the most famous is probably the Geiger counter. A Geiger counter uses a tube filled with an inert gas (e.g. helium, neon, or argon) which becomes briefly conductive when struck by beta particles or gamma rays. The tube amplifies the resulting current pulse and displays it, typically as needle movement, lamp light, or an audible click. Other instruments for detecting radiation include ionization chambers, cloud chambers, bubble chambers, photomultipliers and dosimeters.
What scientist is credited for discovering that atoms emit tiny negative What are the indicators of particles?
Your phrasing is rather sloppy and I have to guess what it is you are really asking, but nonetheless I have an answer. Radioactivity was first discovered by three scientists, Marie & Pierre Curie, and Antoine Becquerel. There are many ways to detect or observe radioactivity, but the simplest is that it affects photographic film as if it had been exposed. For a more sophisticated, modern observation, we use cloud chambers or bubble chambers.
