Sound energy Definition and 18 Threads

I have an acoustics question regarding mounting of a subwoofer enclosure, here is wireframe view of situation: I have a sealed subwoofer box lets assume it is running high power 250 W RMS. It has flanges that come out that have 30 Duro Isolating Pads between the flanges and the base board...

Since thermal energy is the vibration of molecules and sound is too, what is the difference? And why exactly do atoms radiate different energies as a result of vibrations?

So I'm trying to understand how the modulus works in metals. I understand that when the temperature rises, that means that the modulus decreases. But I do not understand exactly what it is or how it affects the way that the molecules would vibrate for instance, as kinetic sound energy moved...

Hi everyone, I am looking to improve the transmission of sound from a small 1/2" electro-mechanical transducer through a plastic medium (about 1/4" thick). I understand plastic is not a great medium for this but I do not have the ability to change this. The defacto setup doesn't work too...

Homework Statement Why is there more heat and sound energy produced with a larger collision? Homework EquationsThe Attempt at a Solution Honestly no clue. I would really appreciate any help! Any videos would also help!

is that possible pls help me!

Hello! I'm new to this website, so apologies if I'm a little off with the way I format this question. Nonetheless: This last year, I've been researching sound energy and methods of focusing, harvesting, and storing this energy. Essentially, I'm looking at the possibility of harnessing sound...

Hi, I need lessons for sound energy-How tension affects the pitch of sounds for 3rd grade. Thank you

Homework Statement "A continuous sound wave with a sound intensity level of 80dB passes through a hole in a wall which has a cross-sectional area of 3m^2. How much energy passes through this hole in 10 minutes, in joules?" If anyone can show me how this problem is solved it's be much...

Is there a way to convert light energy to a sound energy? I read an article and the URL is http://www.photonics.com/Article.aspx?AID=52646 It is described that nano material lenses are used. Is there a much simpler way that I convert light to sound?

i am interested in learning about sound .so please can anybody provide a website for learning about it .

Homework Statement Sound, a form of energy can be modeled by using two distinctly different approaches. a) Describe the propagation of sound energy through air by discussing the motion of individual particles. Include possible mathematical equations that might apply. b) describe the...

need ur help for this one hope sum1 replies

Homework Statement a)A sound wave with an intensity level of 80.1 dB is incident on an eardrum of area 0.600 10-4 m2. Calculate the energy is absorbed by the eardrum in 4.00 minutes in microJ b)The sound level 25.0 m from a loudspeaker is 69.0 dB. Calculate the rate at which sound energy is...

Is it possible to convert sound energy into heat energy (or any other type of energy) so that a loud sound will be almost silenced?

1. Homework Statement The sound level 24 m from a loudspeaker is 66 dB. What is the rate at which sound energy is produced by the loudspeaker, assuming it to be an isotropic source? ____W 2. Homework Equations ? Something to do with Intensity? 3. The Attempt at a Solution...

i might have already posted this i forgot basically one day i was why can't we get more energy from a motor by using its sound waves. but some has thought of that already so... how does he do it. how does it work. [edit: crackpot link deleted]

Dear reader, Is sound Energy or a force? I am confused.:smile:
