the air trapped inside the foam absorbs the sound making it quieterBTW: I KNOW CAUSE I HAD A PROJECT ON THIS AND I GOT AN A+
Metal is a good conductor of sound, so it can actually amplify sound rather than stop it. To stop sound from coming through, you would need to use materials that can absorb or dampen sound waves, such as thick walls with insulation or acoustic panels.
The sound would be like thunder, since thunder also has high amplitudes and frequency also. Usually at the begining of thunder you will listen cracking (krat..kat..krat .........) sound which is high frequency and high pitch. At the time when thundering is almost stop you will listen the heavy /bass sound which is very high amplitude and low frequency (goom.goom....goom...........) sound.
Sound for stop motion video can be created by recording dialogue, sound effects, and music separately, then syncing them with the video during the editing process. You can use a quality microphone to capture clear audio, and editing software to adjust the sound levels for a professional finish. Experiment with different techniques to achieve the desired sound effects for your stop motion project.
Yes, a Faraday cage can effectively stop an EMP (Electromagnetic Pulse) by blocking the electromagnetic radiation from reaching the objects inside the cage.
You can reflect it, absorb it or even diffract it (a bit).
It will depend on what noise levels he is being exposed too. Simple roll up ear plugs do work great. Otherwise you can buy the more expensive noise canceling type ear muffs that stop sound from reaching the ears.
Old people have big noses and big ears because their noses and ears get bigger and bigger each second, but VERY VERYslowly.-j.e.k
Your ears and nose never stop growing.
The Atlas Mountains stop moisture from reaching the Sahara.
You cant stop any one from reaching Oliver Twist.
if very loud sounds enter the ears the vibrations set up in the ear fluid are so strong that they damage the fibers and stop the nerve endings being stimulated. this could produce premanent ear damage and deafness.
One way to use sound to get dogs to stop barking is by using a high-pitched sound or whistle that is unpleasant to their ears. This can help distract them and interrupt their barking behavior. It is important to use this technique consistently and in conjunction with positive reinforcement training to effectively modify their behavior.
I have recently stopped wearing earrings regularly and when people squint they can only just see the holes, but my earrings fit anyway.
Because your jaw is closely connected to your ears and your jaw moves when you swallow. That is also how you wiggle your ears.
Open your mouth and see what comes out of it. If people run away holding their ears then stop immedately. Otherwise you can sing.
To stop sand getting in.
