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.

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.

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.

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?

Hi there, thanks for your comment. Could you please specify your question? The amplitude is made of positive and negative peaks. Are the negative peaks what you meant by "troughs"? Kind regards, Verena

@sweetness583 5 жыл бұрын

@@medel yes that is what I mean: negative peaks. If silence is zero, and sound has a peak of 1, let's say, then what would -1 be?

@medel 5 жыл бұрын

Hi there, excellent question: It’s a bit of complex physics, but basically, sound waves are pressure waves that travel through air as “longitudinal waves”. When the energy compresses the air molecules, that’s a peak (+1). A return to normal pressure is 0. But every action has an equal and opposite reaction, so the air molecules also spread out to a state of negative pressure. That’s a trough (-1). All of this together (plus and minus) makes up the amplitude/volume. There’s a helpful explanation here: hyperphysics.phy-astr.gsu.edu/hbase/Sound/tralon.html. Kind regards, Verena

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) 😀

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
