Understanding Sound Waves | MED-EL

This video describes how sound waves are produced as well as how the frequency and amplitude of a sound are affected by the movement of molecules. Being able to understand sound enables us to replicate it precisely so that we can offer superior hearing performance to our hearing implant users.

The movement of molecules determines the frequency and amplitude of a sound



Frequency is one of 2 key properties of sound. It is determined by the rate of movement of molecules, set into motion by a vibrating object. This movement it is measured in cycles per second, comonly refered to Hertz [Hz]



Frequency is what gives sound a particular pitch. A person with normal hearing can hear sounds in the range of 20 to 20000 Hz. 



The amplitude of a sound is determined by the maximum displacement of air molecules. This displacement leads to pressure fluctuations in air, which are expressed in units called decibel sound pressure level.



The amplitude determines the loudness of a sound.

who else thought it was the end of the world when they heard that sound

God bless this man ya girls will not be failing science

😲😲 so informative!! I usually go ahead of the class and this video made me understand this topic. Kudos keep up the great 👍👍 work

[Philomats]

That was a helpful explanation, thanks.

[gedemahandika]

yea.. this video maybe short but really informative and to the point.. keep making videos please

[yousefedris]

thats awesome man xD u have the skill .. why did u stop?

Hello author, I've recently been working on a mathematical physics chronicles content and I very much need to edit 5 seconds of footage using the footage from the video you created, I really, really need the 5 seconds of material. I'll be sure to credit the source of the footage and @ your channel when I'm done with my work. I very much recognize your work and thanks again. : )
(The above text was translated by me, using a translation program, so please forgive me if I use the wrong words) 😀

Did you use After Effects for the graphics?

Can anyone link to a video that shows this in real scale? I’m trying to visualize how far the displacement of molecules for a given amplitude might be and how that propagates over distance.

This is probably a stupid question but if the peaks in the wave determine how loud a sound is, why don't the troughs mean anything?

Not sure an individual can hear 0 dB SPL (at least, most of them can’t), even refered to 1 kHz 0 dB HL equals something like 7 dB SPL.

I wonder what frequency god spoke at when he spoke the universe into existence. Take a look at the god particle I thinks it’s the closest humanity has ever gotten to discovering it
